## Long description

Pack of 1000 SPAX universal screws T20 half-round head WIROX 4 mm x 30 mm designed for general fastening tasks in wood and composite materials. These screws feature a T20 drive and a half-round head profile that provides a low-profile finish while allowing secure bit engagement. The WIROX coating offers corrosion resistance suitable for indoor and some sheltered outdoor applications. The consistent thread geometry ensures reliable bite and pull-out resistance across a range of timber and panel substrates.
Advantages
The combination of a T20 drive and precision thread reduces cam-out and speeds up installation with powered drivers. The half-round head gives a neat visible finish and distributes clamping force over a larger surface compared to countersunk types. WIROX surface treatment increases resistance to rust and wear without significantly altering screw dimensions. Supplied in a bulk pack of 1000 pieces, the set supports larger projects and reduces the need for frequent restocking.
Suitable for
 General woodworking and carpentry fastening
 Assembly of composite boards and panels
 Interior trim and molding installation
 DIY projects and small construction jobs

How to use
Select an appropriate T20 bit in good condition and use a drill-driver or impact driver with adjustable torque. For hardwoods or dense composite materials, consider pre-drilling a pilot hole to reduce splitting; for softer woods the screw may be driven directly. Drive the screw until the half-round head rests on the surface with firm clamp, avoiding over-torquing which can strip the drive or damage the material. For repetitive work, use a magnetic bit holder or bit extension to improve handling and speed.
Usage recommendations
Store the screws in a dry environment to preserve the WIROX coating. For prolonged outdoor exposure or direct contact with chemically treated timber, verify that the WIROX finish meets the required corrosion class; where higher corrosion resistance is needed, select fasteners specified for exterior use. Wear appropriate eye protection when driving screws and follow standard safety practices for power tools.
