6mm x 30mm A4 316 Stainless Steel Wood Screws – TX25 Torx, Part Threaded, Self Countersinking

Designed for demanding outdoor and marine applications, these premium quality 6mm x 30mm wood screws are manufactured from marine grade A4 316 stainless steel for maximum corrosion resistance and long-term performance. Featuring a part threaded shank, precision cutting tip, and self countersinking ribs under the countersunk head, these screws deliver fast, clean installation with superior holding power in hardwoods and softwoods alike.

The TX25 Torx drive provides excellent bit engagement and high torque transfer, reducing cam-out and making installation quicker and easier compared to traditional screw drives. Similar in performance and design to leading structural wood screws such as SPAX®, these screws are engineered for professional results in construction, landscaping, decking, timber framing, and marine environments.

The advanced cutting tip helps reduce splitting and minimises the need for pre-drilling, while the ribs beneath the countersunk head allow the screw to self countersink neatly into timber for a flush finish.

Fully ETA Approved to ETA 11/0283 and UKTA Approved to BBA UKTA 22/6473, these screws meet rigorous European and UK technical standards for structural timber applications, giving you confidence in strength, reliability, and compliance.

A4 316 stainless steel is the ideal choice for coastal, marine, and high-moisture environments and is strongly recommended for use with high tannin timbers such as green oak, oak, cedar, larch, and red cedar where lower grades of stainless steel may corrode or react.
