Nut Setters & Adaptors
Nut setters and adaptors make light work of driving hex fixings, roofing screws and socketed fasteners without rounding heads or wasting time on site.
If you're fixing cladding, bolting brackets, running coach screws or flying through roofing screws, these are the bits you keep close. Good nut setters and adaptors hold properly, release cleanly and put up with impact driver abuse. You will also find Power Tool Accessories and Drill Bits for matching the rest of your setup before you buy.
What Are Nut Setters and Adaptors Used For?
- Driving hex head screws into sheet metal, roofing panels and cladding goes quicker with nut setters because they grip the fixing properly and stop the driver slipping off under load.
- Fixing Unistrut, brackets, trunking supports and light steelwork is easier with the right adaptor when you need to swap between screwdriver bits and socketed fixings without emptying half the pouch.
- Working on fencing, timber framing and exterior jobs, nut setters help drive coach screws and hex fasteners square so you do not chew the head and end up fighting it back out.
- Using impact driver accessories on first fix and maintenance work, adaptors let you run sockets from compact drivers where a full ratchet or impact wrench would be overkill.
- Keeping mixed fixings moving on snagging and install jobs, bit holders and adaptors save time when you are jumping between drill bits, screwdriving accessories and socket work.
Choosing the Right Nut Setters and Adaptors
Match the holder and socket end to the fixing you actually use most. Wrong size or wrong rating is where the grief starts.
1. Match the Hex Size Properly
If you are driving common roofing and cladding screws, check the hex head size before ordering and do not guess. A loose fit rounds heads, slips under pressure and costs you more time than the right nut setter ever will.
2. Impact Rated or Standard
If the kit is going anywhere near an impact driver, buy impact rated nut setters and adaptors. Standard pieces might be fine in a drill for light work, but site use with repeated hammer action soon finds the weak ones.
3. Length Matters More Than People Think
Short nut setters are fine for open access and faster control. If you are working around profile sheeting, deep channels or awkward brackets, go longer so the chuck is not rubbing against the job all day.
4. Adaptors for Swapping Jobs Fast
If you jump between sockets, bits and pilot drilling, a solid quick change adaptor earns its keep. It is a simple way to keep one driver moving instead of carrying separate tools for every fixing type.
Who Uses These on Site?
- Roofers and cladders use nut setters every day for driving self drilling hex screws into sheet, trim and flashings where a poor fit will slip and mark the finish.
- Sparkies reach for adaptors when fitting tray, trunking brackets and channel supports because they let them swap from pilot hole to hex fixing without changing half the kit.
- Dryliners and fixers use them for metal framing, angle beads and bracket work where speed matters and repeated fastening soon shows up weak bit holders.
- Maintenance teams keep a set in the van for plant covers, gate hardware, HVAC fixings and general repair work where compact access matters more than dragging out larger impact sockets.
- Chippies and fencing crews use nut setters and adaptors for coach screws, structural fixings and external timber work where they need straight drive, decent reach and no mucking about.
The Basics: Understanding Nut Setters and Adaptors
These are simple bits of kit, but getting the type right saves rounded heads, broken holders and wasted time. Here is what matters on site.
1. Nut Setters Grip Hex Heads
A nut setter is made to drive hex head screws and small hex fasteners squarely. Instead of trying to fudge it with the wrong socket or a loose bit, it holds the fixing properly so you can drive faster with less cam out.
2. Adaptors Let One Tool Do More
An adaptor changes the connection at the end of your drill or impact driver, so you can run sockets, bit holders or other screwdriving accessories from the same tool. That means fewer swaps, less kit on your belt and quicker fixing.
3. Impact Rating Changes Durability
Impact rated gear is built to take the repeated hammering from impact drivers. For regular site work, especially metal fixings and long screws, that rating matters because it is what stops adaptors twisting, cracking or wearing out too soon.
Accessories That Keep Nut Setters and Adaptors Useful
A few simple add ons make these far more practical on real jobs, especially when fixings and materials keep changing.
1. Quick Change Bit Holders
Get a decent quick change holder if you are swapping between screw bits and hex drivers all day. It saves dragging bits out by hand and stops the usual faff when you are up steps or hanging off a tower.
2. Impact Sockets
If you are using adaptors to run sockets from an impact driver, proper impact sockets are the safe bet. Standard chrome sockets are not built for that abuse and can split or wear fast on stubborn fixings.
3. Spare Nut Setter Sizes
Keep the common sizes doubled up in the van because they are the ones that go missing first. It is a cheap fix for avoiding a wasted trip when one disappears into insulation, mud or roof sheets.
4. Pilot and Clearance Drilling Bits
When the job needs drilling before fixing, pair these with the right bits for the material. HSS Drill Bits suit metal work, Masonry Drill Bits cover block and brick, and Holesaws & Accessories help when the fixing job turns into a cut out as well.
Choose the Right Nut Setters and Adaptors for the Job
Use this quick guide to sort the type that suits the fixing and the tool in your hand.
| Your Job | Nut Setter or Adaptor Type | Key Features |
|---|---|---|
| Driving roofing and cladding screws all day | Impact rated magnetic nut setter | Correct hex size, strong magnet or secure retention, built for repeated impact use |
| Fitting brackets, channel and general site fixings | Standard or impact nut setter set | Range of common sizes, quick access in the case, short enough for control in tight spots |
| Using sockets from a compact impact driver | Hex to square drive adaptor | Impact rated build, secure fit to socket, good for lighter fastening where a wrench is overkill |
| Swapping constantly between screws and hex heads | Quick change adaptor with bit holder | Fast bit release, less downtime, cleaner changes on steps, towers or awkward access work |
| Reaching fixings past sheet profiles or deep channels | Long reach nut setter | Extra access, better clearance from the chuck, easier alignment on recessed or awkward fixings |
Common Buying and Usage Mistakes
- Buying the wrong hex size is the classic one. The result is slipped drives and rounded fixing heads, so always match the nut setter to the fastener you actually use.
- Using standard adaptors with an impact driver soon wrecks cheap gear. If the driver is impacting all day, use impact rated adaptors and sockets or expect breakages.
- Picking only short setters for every job sounds fine until the chuck keeps fouling the work. Keep a longer option for cladding sheets, channel and recessed fixings.
- Running worn nut setters for too long chews fixings and slows the whole job down. Once the fit gets sloppy, replace them before they cost you more in damaged heads.
- Using a socket adaptor as a substitute for a proper impact wrench on heavy seized bolts is asking too much. These are ideal for lighter fastening and install work, not every high torque job on site.
Magnetic Nut Setters vs Non Magnetic Nut Setters vs Socket Adaptors
Magnetic Nut Setters
Best when you are driving lots of small hex head screws overhead, across roofing sheets or into awkward positions. The magnet helps hold the fixing in place so starts are quicker and dropped screws are less of a pain.
Non Magnetic Nut Setters
A solid choice where you want simple drive engagement without relying on a magnet that can fill with swarf or site dirt. They suit repetitive fastening where access is clean and you are already presenting the fixing square.
Socket Adaptors
These are for turning your drill or impact driver into a compact socket driver. Handy for brackets, plant covers and light mechanical fixings, but not the first pick for heavy torque work where a proper wrench and impact sockets make more sense.
Which One Should You Buy
If the work is mainly hex head screws, buy nut setters in the sizes you use most. If the job changes constantly and includes socket work, add adaptors as well. Most site lads end up carrying both because it saves time.
Maintenance and Care
Clear Out Metal Swarf and Dust
After metal fixing work, wipe the setters and adaptors down and clear out any swarf. Built up filings stop proper engagement and wear the inside faces faster than most people realise.
Check for Twisting and Cracks
Give impact used adaptors a quick look before the next job. If the shank is twisting or the drive end is cracked, bin it. A failed adaptor under load can damage the fixing and the tool chuck.
Replace Worn Sizes Early
The common sizes wear first because they do most of the graft. Once the fit goes loose on the fixing head, replace that size rather than forcing a few more days out of it.
Store Them Properly
Keep sets in their case or a dedicated organiser instead of loose in the van. It stops rust from damp site gear, stops sizes going missing and saves rummaging when you need one fast.
Use the Right Tool for the Load
Do not ask a small adaptor to handle seized or oversized fixings it was never meant for. Using the right driver and the right accessory is the best way to make them last.

Nut Setters and Adaptors FAQs
What are nut setters and adaptors used for?
They are used for driving hex head screws, small hex fasteners and socketed fixings with a drill or impact driver. On site that usually means roofing screws, cladding fixings, brackets, channel supports and general install work where speed matters.
How do I choose the right nut setters and adaptors?
Start with the fixing head size you actually use, then check whether the tool is a standard drill or an impact driver. After that, pick the length for access and buy impact rated versions if they are going to take daily site abuse.
Are nut setters and adaptors suitable for impact drivers?
Yes, but only if they are rated for impact use. That is the honest answer. Plenty of standard adaptors will fit, but repeated hammer action can twist or crack them, so for proper site work an impact rated set is the safer buy.
How do I choose durable nut setters and adaptors for site work?
Look for impact rated construction, a clean accurate fit on the fixing head and solid retention that does not let go under vibration. The durable ones are the ones that stay square on the fixing and do not start twisting after a week in the van.
Can I buy nut setters and adaptors online from ITS?
Yes. You can buy nut setters and adaptors online from ITS with the key sizes and types in stock in our own warehouse. That means less waiting around and next day delivery when the job cannot sit still.
Do I need magnetic nut setters?
If you are starting lots of hex screws one handed, overhead or into awkward sheet work, magnetic nut setters are well worth it. For cleaner bench work or straightforward access, non magnetic versions are often all you need.
