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

Notice

The thread-rolling tip is not suitable for mounting. Thread-rolling tip length is 5xP (P = thread pitch, at diameter M6 P = 1 mm and at diameter M8 P = 1.25 mm).
