Timco A4 Stainless Steel Timber Screws - 6.7x100mm (25 Pack)

The Timco A4 Stainless Steel Timber Screws are designed as a superior alternative to traditional coach screws, primarily for timber-to-timber applications. Manufactured from A4 Austenitic Stainless Steel (316 grade), these screws deliver exceptional corrosion resistance, making them perfect for external use or in highly corrosive environments such as coastal areas or with reactive timbers like Green Oak.

These screws feature a hex head with integrated washer for flush fitting and enhanced load distribution. The helix shank helps remove debris during installation while improving clamping force, and the 50° deep single thread provides a secure fixing with high pull-out resistance.

For easier installation, the 25° sharp point with single slash reduces torque requirements and minimises the risk of timber splitting, even at low edge distances. The single lead thread ensures fast starts and optimised thread acceptance for efficient driving.
