## Long description

Pack of 1000 SPAX universal countersunk screws WIROX 4×16 mm T20 drive designed for general fastening tasks in wood and composite materials. Each screw features a WIROX corrosion-resistant finish, a 4 mm shank diameter and a 16 mm overall length, with a Torx T20 drive for positive bit engagement and reduced cam‑out. The countersunk head enables flush seating in timber and panels, while the thread profile provides secure pull‑in and reliable holding power for repeated installation scenarios.
Advantages
These SPAX screws combine a corrosion-resistant WIROX surface treatment with a universal thread geometry suited to a wide range of timber densities and composite boards. The Torx T20 drive improves torque transfer, allowing consistent drive depth and reducing the risk of stripping. Supplied in a bulk pack of 1000, the set supports larger jobs and repetitive assembly work, providing uniform dimensions and finish across the full quantity.
Suitable for
Structural and non-structural timber fastening
Furniture assembly and interior fittings

High-volume industrial or site installation tasks

How to use
Select an appropriate Torx T20 bit and, if required for precision, pre-drill a pilot hole according to material density and the 4 mm screw diameter. Position the countersunk head flush with the surface or slightly below for concealed finishes. Drive the screw at a steady speed, applying consistent pressure until the head seats evenly; avoid over-torquing to prevent material splitting or recess damage. For repeated installations, confirm bit condition and replace worn bits to maintain reliable engagement.
Usage recommendations
For exterior or moisture‑exposed applications, verify compatibility of the WIROX coating with local environmental conditions; consider additional corrosion protection where required. Use appropriate pilot holes in hardwoods and dense composites and apply consistent driving technique to achieve uniform countersinking and secure joints.
