SS316 Torx Double Countersunk Double Thread Square Cone Point Screw 14-7x50-150 A4

Product Features
316/A4 Stainless Steel for Strong Corrosion Protection: Contains molybdenum, offering resistance to seawater, salt spray, and humid environments. Its anti‑rust performance surpasses that of 304 stainless steel, ensuring long‑term outdoor use without significant corrosion.
Torx Recess for High Torque and No Cam‑out: Distributes force evenly across multiple contact points, preventing bit stripping or slipping even during long‑screw installation. Compatible with power tools and durable for repeated driving and removal.
Double Countersunk Head Prevents Surface Damage: The dual‑layer conical countersink allows the screw head to embed fully into the material, avoiding edge chipping on wood surfaces and delivering a smooth, aesthetically pleasing finish.
Double Thread for Gap‑Free Joining: The front thread anchors the base wood, while the rear plain shank pulls the top board tight, effectively eliminating joint gaps and preventing loosening or warping of the panels.
Square Cutting Point for Easy Driving: The four‑edged tip cuts through wood fibres autonomously, allowing pre‑drilling to be omitted in hardwoods and preservative‑treated timber, reducing the risk of splitting.
Full Length Range for Thick Wood Applications: Available in multiple lengths from 50 to 150mm, meeting the requirements of heavy‑duty connections such as timber joists, thick wooden beams, and decking boards.
