Screw SPAX Flat countersunk head T-STAR plus, zinc, 30 mm length, Ø 4 mm, thread 25 mm, pack 200

SPAX Flat countersunk head screw T-STAR plus in zinc is a 30 mm wood screw designed for secure and reliable fastening in furniture assembly, carpentry and general wood applications. The screw has a 4 mm diameter with 25 mm threaded length and a flat countersunk head that allows a flush finish. The T-STAR plus drive ensures stable bit engagement and reduces cam-out for efficient installation. Supplied in a pack of 200 pieces, these screws are intended for universal indoor wood use and offer features that reduce splitting and the need for pre-drilling in many wood types.

Advantages

The screw's 4CUT tip and ground serrations enable screw-in without pre-drilling in many wood situations and actively reduce splitting by displacing fibres rather than cutting them. The T-STAR plus drive provides optimal force transmission and secure bit grip, lowering the risk of cam-out and making driving faster and more controlled. Blue zinc plating gives basic corrosion resistance suitable for interior use, and the flat countersunk MULTI head mills into wood and stops on metal to deliver a clean, flush surface.

How to use

Select an appropriately sized T-STAR plus bit and secure it in the driver. For many softwoods and engineered wood products the 4CUT tip and serrations allow driving without pre-drilling, but for hardwoods or when working close to edges, a pilot hole is recommended to avoid splitting. Position the countersunk head flush with the surface and drive the screw until the head is level with the material. Use a controlled torque setting on cordless drivers to avoid over-driving, and ensure the workpiece is clamped or supported during fastening.

Usage recommendations

Use these screws primarily for interior wooden applications. For exterior or high-corrosion environments, select a stainless or specially coated fastener. When assembling load-bearing structures or working with hardwoods, pre-drilling and appropriate fastening guidelines should be followed to ensure joint integrity.
