Product Features
SS304 Stainless Steel Material: Resists rain and moisture, does not rust easily, and will not stain timber. It ensures stable and durable performance during long‑term outdoor use.
T25 Torx Recess: Provides tight bit engagement and high torque transmission, reducing the risk of cam‑out during installation and enabling efficient operation with power tools.
Wide Large Countersunk Head: Offers a large load‑bearing area, sinks fully into the board after tightening for a flush surface, and minimises the risk of compressing or cracking the wood.
Nib Point with Cutting Edges: Features built‑in chip grooves, allowing pre‑drilling to be omitted in hardwoods, effectively preventing splitting and making driving easier.
12G Coarse‑Thread Shank: Delivers strong thread grip and excellent pull‑out performance, ensuring long‑term resistance to loosening.
Multiple Length Options: Available in gradient lengths from 65‑90mm, accommodating various combinations of board thicknesses and joist dimensions.
