Bi-Metal self-drilling screw austenitic stainless steel

Wing-Tip Self-Drilling Screws - CSK - For Timber to Heavy Section Steel - Bi-Metal

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.

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.
