DG Impact Torx Head Screws are a reliable, cam-out-resistant fixing solution designed for use with impact drivers on site or in the workshop. Available in 3.5 mm diameter across four lengths, they are suitable for timber joinery, general construction and boarding applications.
Specifications
| Property | Detail |
|---|---|
| Drive Type | Torx (star drive) |
| Diameter | 3.5 mm |
| Available Lengths | 20 mm, 25 mm, 30 mm, 40 mm |
| Head Type | Impact Torx countersunk |
| Compatible Driver | Standard Torx impact bit |
What it's used for
- Fixing timber joinery components including door linings, frames and architraves
- General construction fixing into softwood studwork, noggins and battens
- Securing subfloor and loft boarding where a clean, countersunk finish is required
- Workshop assembly of furniture and cabinet carcasses where positive driver engagement matters
Fitting and handling
Use a correctly rated Torx impact bit matched to the screw size to maintain positive engagement and avoid stripping the drive recess. Pre-drilling a pilot hole is recommended in hardwoods or close to the end grain of softwoods to prevent splitting. Store fixings in a dry environment to avoid surface oxidation between uses.
FAQ
What Torx bit size do I need for 3.5 mm Impact Torx screws?
A T20 Torx bit is the standard fit for 3.5 mm screws of this type. Using an impact-rated bit rather than a standard bit will prolong bit life and reduce the risk of cam-out under load.
Are these screws suitable for outdoor use?
These screws are intended for general timber and joinery applications. If fixing in an exposed or high-moisture environment, we would recommend checking the finish specification and considering a screws rated for exterior use. Contact Nottage Timber Merchants for guidance on the right fixing for your project.
Can I use these with a standard cordless drill rather than an impact driver?
Yes. The Torx drive works with any standard T20 bit in a cordless drill or screwdriver. The impact-compatible design simply means they perform reliably under the higher torque output of an impact driver without camming out.
Pair these fixings with our range of door linings and frames for a complete joinery solution. Nottage Timber Merchants supplies trade and retail customers across Bridgend and South Wales, with next-day delivery available to many local areas.
