Brad Nails 18G Straight
18G straight brad nails are fine-gauge fixings designed for detailed trim, moulding and panel work. Ideal for light second fix applications, they offer a strong enough hold for trims and beads while leaving a near-invisible finish that’s easy to prep and paint over.
What Are 18G Straight Brad Nails Used For?
These brads are perfect for finish carpentry where the appearance of the fixing matters just as much as holding strength. They’re typically used in delicate or decorative work, including cabinetry and fit-out jobs.
- Trim and Beading – Fix quadrant, scotia and small mouldings neatly with no cracking or splitting.
- Wall Panels and Cladding – Nail thin boards or MDF to frames without damaging the visible face.
- Lightweight Cabinet Assembly – Secure rear panels, trim rails or pelmets without bulky fixings.
- Window Linings and Stops – Hold detail trims flush against sashes or reveals with minimal touch-up needed.
Who Uses 18G Straight Brad Nails?
Used widely by carpenters, joiners and decorators, these brads are perfect for work where looks matter — especially in tight corners or for pre-painted materials.
- Finish Carpenters – Fit fine trims and decorative features during second fix.
- Joiners – Use in wardrobe builds, kitchen installs and lightweight assembly.
- Fit-Out Contractors – Ideal for panelling, boxing-in and tight-space finishing.
- Decorators – Install rails or trims ready for painting with minimal filler or sanding.
What Jobs Are 18G Straight Brad Nails Best At?
These nails shine when clean results matter — especially with soft timber, painted trims or lightweight sheet materials.
- Fixing Narrow Trims or Scotia – Tack fine edge trims flush to walls or boards without surface bruising.
- Securing MDF Beading or Moulding – Fire brads into pre-primed MDF without shattering edges.
- Pinning Decorative Boards or Slats – Hold vertical slats, v-groove panelling or tongue-and-groove neatly.
- Fitting Lightweight Door Stops – Place internal stops or rebated edge pieces with precision.
- Installing Pre-Finished Trim – Avoid visible holes when pinning painted or veneered trims onsite.
How to Choose the Best 18G Straight Nails
Use this checklist to get the best brads for your finish tool and the job ahead:
1. Nail Length
Common lengths range from 15mm to 50mm. Use shorter for trims and longer for cladding or frames.
2. Gauge & Shank
18G brads are finer than 16G — perfect for minimal filling. Use on softwoods, MDF, and cabinet material.
3. Finish Type
Galvanised = rust resistant. Stainless = best for damp or bathroom work. Bright steel = dry interiors only.
4. Head Profile
Small round heads allow clean sink-in and fast filling. Ensure you don’t overdrive in soft material.
5. Tool Fit
Check your brad nailer accepts 18G straight brads within your required length range before loading up.

FAQs
Are 18G brads strong enough for skirting?
Only for very light skirting or with adhesive. 16G is better for heavier trims. 18G is best for fine finishes and trim-only holds.
Can I use 18G brads on MDF?
Yes — but avoid driving too close to edges. Use short brads and go easy on depth to avoid surface blowout.
What’s the main advantage over 16G brads?
18G brads are less visible and require minimal filling. Perfect for final finish or decorative trim installation.
Will 18G brads split timber?
Not usually — they’re fine for softwoods and MDF. Still best to avoid edges or tight corners on fragile materials.
Can I reuse brads if I remove them?
No — brads bend or warp on removal. Always use fresh strips for clean, consistent results.
