About this item
- Unmatched Corrosion Protection: Featuring a premium black Ruspert ceramic coating that withstands over 1000 hours of salt spray testing with no red rust – far outperforming standard zinc plating. Ideal for outdoor, coastal, marine, or harsh environments where moisture, salt, and weathering cause ordinary screws to fail prematurely.
- Self-Lubricating Design: The advanced Ruspert coating acts as a built-in lubricant, significantly reducing insertion torque for smoother, faster driving with less effort and tool wear.
- Optimum Thread Performance: Serrated V-threads cut a precise thread into the base material for maximum grip across all masonry types, while allowing easy adjustment or removal without damage.
- Professional Finish: Flat countersunk head with five locking ribs ensures a flush, secure fit – perfect for door and window frame installations.
- Non-Expansion & Removable: Eliminates substrate stress and provides a reusable, one-piece fixing system.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
