Knipex Mole Grips
Knipex mole grips lock up hard on pipe, flat bar and awkward fixings when two hands are not enough and slipping jaws will only waste time.
When you need to clamp, hold or free off something that will not stay put, this is the kit you reach for. Knipex locking pliers are proper site gear for welding prep, seized fasteners and temporary holding jobs where ordinary pliers just let go. If you already rate Knipex Tools, this range is worth a look.
What Are Knipex Mole Grips Used For?
- Clamping rounded nuts, damaged bolt heads and stubborn fixings gives you a harder bite than standard pliers when there is nothing decent left to grip.
- Holding sheet metal, flat bar or brackets in place during tack welding or drilling saves chasing moving material across the bench or floor.
- Pinching off, securing or steadying pipework and fittings helps plumbers and fitters keep control while cutting, loosening or lining parts back up.
- Locking onto hot, oily or awkward parts in workshops, plant rooms and site cabins keeps your hand away from edges and surfaces you do not want to grab directly.
- Using Knipex grip pliers for temporary hold-and-release jobs on refurbs and repairs speeds up work where a clamp is too bulky and standard pliers will not stay shut.
Choosing the Right Knipex Mole Grips
Sorting the right one is simple. Match the jaw shape and size to what you actually grip most, not the odd job once a year.
1. Curved Jaws for General Grip
If you are mostly grabbing bolts, pipe and rounded sections, curved jaw Knipex vice grips are the sensible starting point. They bite better on mixed shapes and earn their keep on everyday repair and install work.
2. Straight Jaws for Flat Stock
If you do more metalwork, bracket work or welding prep, go for straight jaws. They sit cleaner on flat bar, sheet and folded sections, so the grip is more predictable and less likely to twist off line.
3. Pick the Length for Access
Shorter Knipex locking grip pliers are better in cupboards, plant rooms and crowded service voids. Longer ones give you more leverage and reach, which matters when a fixing is seized or buried behind other kit.
4. Check the Release and Adjustment
If you are opening and closing them all day, do not overlook the release lever and adjusting screw. A smooth quick release saves faffing, especially on repetitive clamping jobs or when wearing gloves.
Who Uses These on Site?
- Plumbers and heating engineers keep Knipex mole grips in the bag for seized valves, rounded compression nuts and holding back pipework while another fitting is tightened.
- Fabricators and welders swear by Knipex locking pliers for gripping plate, flat stock and brackets during set-up, especially when a quick temporary hold is all that is needed.
- Mechanics, plant fitters and maintenance teams use them for stubborn fasteners and greasy parts where ordinary pliers just skate off and waste your knuckles.
- General builders and site fixers reach for Knipex self grip pliers on repair work, snagging and awkward holding jobs where a small clamp would be slower and bulkier.
Choose the Right Knipex Mole Grips for the Job
Use this quick guide to sort the right jaw style and size for the work in front of you.
| Your Job | Knipex Mole Grips Category or Type | Key Features |
|---|---|---|
| Freeing rounded nuts and gripping pipe on repair work | Curved jaw locking pliers | Better bite on round sections, mixed shapes and worn fasteners |
| Holding brackets and flat bar for drilling or tack welding | Straight jaw grip pliers | Cleaner contact on flat material and less chance of twisting |
| Working in cupboards, service risers and tight plant spaces | Compact locking pliers | Shorter body, easier one handed placement and better access |
| Getting extra leverage on seized fixings or awkward assemblies | Longer locking grip pliers | More reach, more leverage and better control away from hot or sharp parts |
Common Buying and Usage Mistakes
- Buying the biggest pair by default sounds sensible, but oversized mole grips are clumsy in tight spots and harder to set properly on smaller fittings. Match the length to the access and the work.
- Using curved jaws on flat stock all day gives a less secure hold and can mark the material badly. If most of your work is on plate, brackets or sheet, straight jaws are the better shout.
- Over-tightening the adjuster to make up for poor jaw choice just chews fixings and makes the release awkward. Set the tool to clamp firmly, then switch jaw type if the grip still is not right.
- Treating locking pliers like a permanent clamp is where frustration starts. They are ideal for temporary holding and awkward grips, but for long bench clamping use a proper clamp instead.
- Ignoring wear, swarf and dirt in the mechanism makes the release stiff and the action rough. Keep the pivot clean and the moving parts lightly lubricated so they still lock and release cleanly.
Curved Jaw vs Straight Jaw vs Compact Locking Pliers
Curved Jaw
This is the all-rounder for site repairs and general gripping. It suits pipe, rounded fasteners and mixed shapes best, which is why it is usually the first pair in the van.
Straight Jaw
Better for flat bar, angle, sheet and welding set-up where you want square contact and less twisting. If you do fabrication or bracket work often, this style is usually the smarter buy.
Compact Locking Pliers
These come into their own in service cupboards, under sinks and around packed pipe runs. You lose some leverage, but gain the access that larger pliers simply cannot give you.
Maintenance and Care
Clean the Jaws After Dirty Work
Wipe off swarf, filler dust, oil and welding debris after use. Dirty jaws grip worse and can slip when you least need it.
Keep the Pivot Moving
A small drop of light oil on the pivot and release mechanism keeps the action smooth. If the release starts sticking, sort it early before it turns into a two-handed fight.
Store Them Dry
Do not leave them wet in the van or at the bottom of a bucket with other steel tools. Dry storage helps stop surface rust on the jaws and screw.
Check Jaw Wear and Alignment
If the jaws are badly worn, burred or no longer meeting properly, the grip will suffer. Dress off light burrs, but replace the tool if the hold is no longer trustworthy.

Knipex Mole Grips FAQs
What are mole grips used for?
They are used for locking onto parts so you can hold, clamp, twist or free them off without constantly squeezing the handles. On site that usually means rounded nuts, seized bolts, pipe, flat bar, brackets and welding set-up where normal pliers will not stay put.
What's the difference between mole grips and locking pliers?
In day to day trade use, there is not much in it. Mole grips is the name most lads use on site, while locking pliers is the more general product name. The key thing is jaw shape, size and release design, because that is what changes how well they suit your job.
Do Knipex mole grips have a quick release?
Yes, Knipex locking pliers are designed to lock firmly and release without a wrestling match. That matters when you are moving from one clamp point to the next or working with gloves on. You still need to set the adjuster properly though, because over-tightening any locking plier makes release harder than it needs to be.
What sizes do Knipex mole grips come in?
Knipex mole grips come in a range of lengths to suit different access and grip jobs. Smaller sizes are better for service work, cupboards and tighter spaces, while larger pairs give more reach and leverage for heavier fittings, fabrication and stubborn fixings.
Are Knipex locking pliers suitable for welding work?
Yes, they are a solid choice for welding prep and temporary holding. They are especially useful for keeping brackets, tabs and flat stock in place while you tack up. Just make sure you pick the right jaw style for the material and do not expect them to replace a dedicated clamp on heavier fabrication.
