Trim Head Stainless Steel Screws

From £6.06 (inc VAT) £5.05 (ex VAT) per pack (100 pcs)

With their tiny (6mm diameter) heads, Silva's stainless-steel finishing trim screws provide a neat, professional finish. They are suitable for a wide variety of exterior applications where a discreet screw head is preferred.

The star drive head provides a very positive engagement with the screwdriver bit. Once you try star drive screws, you'll never use an ordinary screw again. They will outperform slotted, Philips, Pozi, and square drive screws in every respect. The deep six-point star-shaped recess enables the driver bit to lock-in, and because there is a greater area of contact, the bit grips the screw tighter, reducing installation torque. Combine this with a sharp cutting tip that bites into the wood, along with a serrated thread, and you have a seriously impressive screw that drives effortlessly into most wood types.

A Reliable Screw for Your Outdoor Projects

Whether you are a professional or a do-it-yourselfer, you need a screw that is fast and easy to install, and most importantly, is reliable. Silva's star drive stainless steel finishing trim screws drive effortlessly into most wood types and are guaranteed to reduce the installation time on any project significantly. By saving you time, they'll be saving you money!

Anyone who's ever driven a screw in knows how annoying cam-out is - when the bit slips out of the screw head as torque increases. It's not only frustrating, but it can also damage the screw head, preventing it from being driven in or out. The improved engagement of the star drive virtually eliminates cam-out and will pull wood components tightly together with ease.

A star drive bit is included free with each box. We recommend you buy a few spares, especially if you are working on a big project.

Why Stainless Steel?

Stainless steel offers the ultimate level of corrosion resistance. Unlike some steel fasteners, it won't react with stain-causing tannins present in some wood species like Western Red Cedar and Oak. Stainless steel is a softer metal than carbon steel, and it will flex to some extent; however, this is advantageous, particularly for decking. Exterior wood will swell and shrink by a small amount as moisture is absorbed in the winter months and released in the summer months. Stainless steel screws can flex without breaking to a certain degree as the wood expands and contracts.
