Product Description

 

· Designed to attach the steel plate or aluminium
· High Anti -Corrosion Resistance for extended life cycles
· Material SUS A2-304 with case-hardened sharp point

Bi-Metal self-drilling screw austenitic stainless steel

A self-drilling, bi-metal screw capable of tapping threads into the sturdiest of substrates while also achieving maximum rust protection. 

The utilization of the hardened, SS410/SS420/carbon steel tip and lead threads eliminate the need for pre-drilling and give way to fast, easy application. This allows builders to use only one tool instead of two, subsequently driving down installation time, labor costs, and tool maintenance costs.

Fastens sheet metal fast: used extensively for side-lap stitching on exposed fastener metal panel roofs.

Assembled with EPDM (Ethylene, Propylene and proportion of Diene) bonded washer for safe sealing of every screw

Environmental protection ruspert coating, which has a 1000-1500 hours' salt spray test time and multi-color matching, it provides a better barrier to prevent the corrosion.
