Spax T-Star Plus Stainless Steel All-Purpose Screws

Overview

This is a Spax T-Star Plus all purpose screw in A2 stainless steel, sized 5mm diameter by 50mm length with a countersunk head and partial thread, sold 200 to a box. It is built for general outdoor and multi material use rather than one specific job.

The 4CUT point and corrugated thread profile are Spax's answer to pre-drilling: four cutting edges start the hole and the thread separates wood fibers instead of splitting them, so the listing states pre-drilling generally is not required, though that depends on the wood. The T-STAR (T20 style) drive with a guide pin is meant to keep the bit seated during overhead or one handed driving, but the bit itself is not included in the box.

• 5mm x 50mm, A2 stainless steel
• Countersunk head, partial thread
• T-STAR plus (T20) drive with guide pin
• Made in Germany, TUV certified

Who it's for

Fits outdoor building and repair work in wood, where a screw needs to sit flush and resist corrosion, and where the installer wants to avoid pre-drilling on most wood species. Not for anyone without a T20 driver bit already on hand, since none is included.

Pros and cons

Performance notes

A2 stainless steel gives the screw its outdoor corrosion resistance, while the multi cut tip mills into wood but is designed to stop biting once it reaches metal, useful when fastening wood to a metal bracket. Partial thread pulls the top piece tight against what is underneath rather than threading all the way to the head.
