A2 stainless steel with drill tip and thread made of hardened steel. Screwing on of steel and aluminium profiles in steel and aluminium without over-turning ≤ 2 mm

The sealing washer consists of an A2 stainless steel metal back with vulcanised seal made from high-quality EPDM

The thread-free part (undercut) below the screw head prevents the screw from over-tightening or stripping and thus ensures that splice plate screw connections in thin metal profiles are safe from working loose.

Suitable for component combinations tI/tII in accordance with approval ETA-10/0184
