KEY POINTS
•
Reduced diameter drilling point ensures highest possible
withdrawal resistance in thin gauge steel substrates.
•
Super hard (>55 HRC), super sharp drilling points ensure fastest
possible drilling times and reduce “walking” of point on substrate
surface.
•
Reduced-diameter TEK® 5 self-drilling point improves
withdrawal resistance (pull-out) in heavy-gauge steel substrates.
•
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.
