Self-tapping screw CH78E hex head with underhead locking serrations

Serrated hex head self-tapping screw CH78E

Serrated hex head self-tapping screw CH78 | CELO

Product overview

The CELO serrated self-tapping screw CH78E is specifically designed for demanding environments where constant movement or vibration compromises the stability of the joint. Its integrated underhead locking serrations slightly bite into the metal surface upon completion of tightening, acting as a safety brake that locks the screw and prevents loss of mechanical tension over time.

Manufactured from carbon steel with a protective zinc-plated coating, the screw features a type C point and a full self-tapping thread according to the ISO 1478 standard to ensure a firm grip on steel sheets, aluminum, and light alloys.
