Evolution A4 Stainless Steel WoodMaster Pozi Countersunk Wood Screws
Designed for universal fixing to wood, chipboard, MDF, plastics, and composites where a stainless steel version is required.
Head Style - Double countersunk with nibs
Shank Material - Stainless Steel
Material Grade - AISI 316 (A4) / EN 1.4401
Key Points
- Double countersunk head improves neck strength, reducing head shearing in high-torque applications.
- Nibs enable smooth self-countersinking in both timber and sheet material applications. The nibs cut the wood surface, trimming from the edge of the drilled hole, ensuring the screw is driven flush to the wood surface every time.
- Helically fluted milling thread clears drilling debris and reduces driving torque.
- High-quality aggressive thread form improves penetration and reduces driving torque.
