SPAX universal countersunk head wood screws T10 WIROX 3 mm x 20 mm, 1000 pcs

SPAX universal countersunk head wood screws T10 WIROX 3 mm x 20 mm come in a pack of 1000 and are designed for general woodworking, joinery and DIY applications where a flush, countersunk finish is required. The screws feature a WIROX corrosion-resistant surface and a T10 drive for secure bit engagement. With a 3 mm shank diameter and 20 mm length, these fasteners provide reliable hold in a variety of soft and hard wood types while minimising the risk of splitting when used with appropriate pilot holes or pre-drilling techniques.

Advantages

These SPAX wood screws combine a countersunk head profile for a neat, flush finish with a corrosion-resistant WIROX coating that improves durability in indoor and covered outdoor environments. The T10 drive recess offers good torque transfer and reduced cam-out, while the universal thread geometry and optimised point make insertion easier and reduce the need for excessive force. The consistent dimensions and high pack quantity support efficient project work and reduce interruptions for restocking.

How to use

Select a matching T10 bit for your drill or screwdriver. For best results in hardwood or near edges, drill an appropriate pilot hole first to reduce splitting; in many softwoods the screw can be driven directly, but a pilot or countersink may still be beneficial. Position the countersunk head flush with the wood surface by driving until the head sits level, taking care not to over-torque which can strip the recess or damage the substrate. For repeated or power-driven insertion, use a depth stop or clutch setting to maintain consistent embedment.

Usage recommendations

Store screws in a dry environment to preserve the WIROX finish. For exterior or permanently exposed applications, evaluate corrosion requirements and consider alternative corrosion classes or stainless steel fasteners. When fastening near edges or end grain, use appropriate pilot holes and avoid excessive torque to prevent splitting.
