Thread-rolling screw with large countersunk head for securing floor panels to steel substructures



Self-tapping screws form a nut thread in cast blind holes, rim holes and drilled, lasered and punched sheet metal parts. Unlike thread cutting, self-tapping does not interrupt the material structure in the receiving thread. Instead, the material is displaced and strain-hardened.

Notice

The grooving tip is not suitable for mounting. Grooving tip length is 5XP (P = thread pitch, at diameter M8 P = 1.25 mm).
