Tacwise 1069 Type 91 / 18 mm Stainless Steel Narrow Crown Staples with Divergent Points (Pack of 1,000)

What it is

These are precision-cut, narrow crown staples in a Type 91/18mm format, made from stainless steel with divergent points. The pack contains 1,000 staples and is designed for fixing through tougher materials or when a deeper staple drive is required. On the page you’ll find these staples described as equivalent to Rapid 606, Arrow C4 and Novus C staples in terms of size and function.

Why you’d choose them

If you’re working across the grain or with wood that tends to split, the divergent points and narrow crown help maintain grip without splitting the wood. The stainless steel construction offers corrosion resistance, suggesting longevity in both indoor and outdoor-ish environments, such as panelling, cladding and garden structures where moisture exposure is a consideration. It’s a pragmatic option when you need a robust fastener that’s compatible with common 91/18mm staple sizes.

Strengths and limitations

On the plus side, these staples provide holding power for wood-to-wood applications and are well-suited for floors, panelling, partitions, door frames, fencing and garden buildings, as described in the product notes. They’re useful when a longer reach is needed and when you want to resist corrosion over time. A potential limitation is that, like all stainless steel staples, performance depends on the stapler you’re using, compatibility is stated with Tacwise 191 series and some other brands, but you should always verify that your tool accepts 91/18mm staples before purchasing.

Who they’re for

They're aimed at tradespeople or keen DIYers tackling medium to heavy-duty woodworking tasks: flooring installations, paneling, framing, or garden constructions where a cavity or deep penetration is required and where moisture resistance matters.

When they make sense

Consider these staples if you prioritise a secure hold across the grain and need staples of 18 mm length. They’re a sensible choice when you want a durable, corrosion-resistant option that pairs with compatible Tacwise and other tackers able to feed 91/18mm staples.

What to check before buying

• Confirm your stapler’s compatibility with 91/18mm staples and divergent-point variants.
• Check whether you need stainless steel for corrosion resistance in your project’s environment.
• Ensure the staple size aligns with the material thickness and the depth you require.

How this compares to other approaches

Compared with shorter or wider-crown staples, these 18 mm narrow crown staples with divergent points offer a balance between grip strength and minimising splitting when fixing across the grain. If you prioritise pace and lower material stress, other options might suit lighter tasks, for stubborn woods or outdoor-ish builds, this stainless steel, deeper-drive solution can be preferable.

Practical use case

Imagine fitting internal panelling where boards run across the grain. The narrow crown helps keep the surface tidy, while the divergent point boosts entry and holding power through tougher sections. You’ll likely notice fewer splits and a more secure fit in thicker boards compared with standard staples.

FAQ (based on available information)

• Q: Are these compatible with all Tacwise staplers? A: They’re compatible with Tacwise 191 12V, 191 20V, 191EL and Duo 35 staplers, and can be used with Stanley, Rapid, Arrow and similar tackers that take 91/18mm staples, but you should always check compatibility with your tool before purchasing.
• Q: Do they resist corrosion? A: They’re made from stainless steel and marketed with corrosion resistance, which is advantageous for longer outdoor or damp environments.
• Q: Do they prevent wood splitting? A: The divergent points and narrow crown are designed to hold across the grain with reduced splitting risk, though results depend on wood type and project conditions.

Final decision

Is it worth it? Worth considering if you need a durable, corrosion-resistant 91/18mm staple for across-the-grain fixes and deeper penetration, especially when working with tougher woods or panels. It’s a sensible option for: projects where holding power and longevity matter, and where your stapler supports this size. It may not be the best choice if your task is light-duty or your tool isn’t compatible with 91/18mm staples.
