KEY POINTS
•
Bi-metal fasteners have a hardened carbon steel drilling point (AISI
C1022) brazed to a stainless steel (AISI 304/ EN 1.4301 (A2)) body
and head.
•
The dome-head design contributes to a neat and professional look
while maintaining the structural integrity of the fastened components.
•
The compression disc is a key feature for weather resistance. The
EPDM material provides an effective seal against water and environmental elements, preventing water ingress and potential damage
to the fastened materials. The stainless steel compression disc
ensures durability and maintains the tight seal over time.
