What are finish nails?
The term “finish nails” covers a range of nail types, including brad nails, bullet head nails and casing nails. Finishing nails are the industry standard for internal joinery and second-fix applications. This is why they are sometimes referred to as second fix nails.
Engineered with a low-profile, reduced head, these fixings sink below the timber surface to leave minimal holes for a clean finish. They provide neatness but offer far superior holding power for heavy skirting boards and architraves.
Our trade stock includes straight and angled collated finish nails to match your specific nail guns. These steel wire nails (sometimes called pins) deliver the precise mechanical strength required by professional carpenters on demanding site work.
Types of finishing nails by gauge
These premium fixings are engineered for internal joinery, shopfitting installations, and precise high-end timber trimming. Collated finish nails range between 14-gauge and 18-gauge in size.
15-gauge
These are thicker, heavy-duty 15-gauge nails (pins) designed to offer maximum structural holding capability on structural internal trims.
15G Angled DA
These nails feature a steep angle to fit easily into tight corners. The heavy gauge steel wire provides excellent structural holding for heavy door casings and substantial skirting boards. 15G angled DA nails run smoothly through high-performance cordless and pneumatic finish nailers, ensuring dependable results on busy commercial sites. Choose from various lengths to suit your specific job requirements. Why not add a box to your basket today?
15G Hardened steel
Engineered from high-carbon steel, these tough products pierce dense hardwoods and masonry sub-bases without bending. They solve the common issue of fastener deflection in tough construction setups. These 15G hardened steel finishing nails are perfect for securing structural grounds or exterior trim where standard pins fail. The protective coatings prevent surface staining, keeping your carpentry looking clean. Every strip is built to withstand high driving impacts.
16G finish nails
These are the ultimate all-rounder gauge for standard second-fix installations across domestic and commercial projects.
16G Angled
Our angled 16G finish nails offer great clearance when pinning detailed crown mouldings or corner architraves. The slant allows precise placement in restricted spaces without marking the timber surface. We stock 16g angled nails compatible with brands like Tacwise to ensure flawless firing without tool jams. These products deliver the neat finish needed to pass strict client inspections. They are perfect for shopfitters needing rapid production on-site.
16G straight
These straight second fix nails are the industry standard for daily internal trim work. They leave a tiny entry hole that requires minimal filler before painting. These versatile finish nailer nails perform perfectly in straight-magazine tools across all major site platforms. We supply durable 16G straight galvanised and stainless steel finish nail options to resist corrosion in damp environments.
18-gauge finish nailer nails
Specifically known as brad nails, these are still a type of finishing nail. For our extensive selection, view our 18G brad nails page.
Other gauges
Although not sold on our site, some manufacturers also have 14-gauge and 17-gauge nails for sale.
Note: 23-gauge pins are not considered finish nails. They are headless pins used in pin nailers for delicate mouldings and fine joinery.
Standard lengths of collated finish nails
Choosing the correct wire gauge and fastener length ensures clean countersinking and prevents the timber from splitting on site. Here is a list of the standard finishing nail lengths used in the UK building industry:
- 15mm to 20mm – best for thin backing boards, decorative cabinet trims, and lightweight fine carpentry tasks
- 25mm – perfect for scribing pieces, small internal trims, and replacing fine panel pins
- 32mm to 38mm – the standard choice for window beads, architraves, and secure window board installations
- 50mm – ideal for driving through skirting boards or external cladding into hidden structural timber frames
- 64mm – built for thick door casings, heavy structural trim, and deep timber-to-timber anchoring
These premium second fix nails are fully compatible with leading finish nailers, including DeWalt and gas-powered Paslode platforms.
Benefits of second fix nails
Here are seven of the main benefits to expect:
- Clean concealed finish – engineered with small heads, these second fix nails countersink cleanly away from sight to provide a discrete countersunk finish
- Fast nailer compatibility – precision-manufactured strips ensure flawless nailer performance, keeping your second-fix tools firing smoothly without any costly downtime or timber jams
- Invisible glue nail fixing – these fasteners provide a concealed glue-joint pinning method, clamping detailed joints firmly together while the woodworking adhesive cures permanently
- Reduced timber splitting – the thin wire diameter ensures minimised grain splitting, protecting expensive pre-finished architraves and detailed window trims from cracking open
- Smooth penetration action – a sharp diamond point guarantees clean surface penetration, driving the wire straight into the wood with minimal force required
- Strong holding performance – these rigid steel nails deliver maximum mechanical grip, keeping heavy decorative timber fixtures anchored securely to the structural grounds behind
- Versatile wood applications – fastening varied timber profiles perfectly, they are the go-to choice for cabinetry assembly, panelling, and general internal renovations
Material options
Choosing the right metal coating ensures your second-fix timber projects stay securely anchored and stain-free over time.
Galvanised steel nails
These carbon steel wire products feature a protective zinc coating to resist moisture from the interior. They are perfect for daily internal carpentry use, including fixing architraves, door linings, and decorative mouldings in dry, climate-controlled domestic rooms.
Stainless steel nails
Offering maximum rust protection, these premium marine-grade collated finish nails are vital for damp areas. Stainless steel nails prevent black timber staining in external cedar cladding, kitchen installations, bathroom trim work, and high-exposure coastal environments.
Hard steel concrete nails
Engineered from high-carbon hardened wire, these tough pins pierce sub-bases effortlessly. Use these finish nailer nails for driving timber grounds directly into brickwork or cured blockwork.
