Long-lasting corrosion resistance - with 304 stainless steel and black oxidised finish
304 stainless steel resists corrosion and rust; the black oxidised surface adds a protective layer and reduces surface damage. Burr-free machining improves contact between head and material.
Suitable for outdoor or humid environments, reducing the need for frequent replacement. Keeps connections solid where moisture or mild corrosion is a concern.
Neat, flush finish – thanks to flat countersunk head
Flat countersunk heads are shaped to sit level with the receiving surface once installed, eliminating raised protrusions. Countersinking distributes head contact across the material.
Creates tidy, snag-free surfaces ideal for furniture and visible panels. Reduces the chance of catches or interference with moving parts.
Secure installation and even clamping – with Phillips cross groove and full threading
Cross-shaped Phillips groove gives screwdriver blades a larger contact area for torque transmission, while full threads ensure uniform engagement along the fastener. Clear, deep threads improve bite and reduce stripping risk.
Simplifies repetitive assembly and lowers the risk of damaged heads during installation. Produces consistent clamp force for reliable joins.
