Böllhoff Releases HITSERT® Screwlock – an Efficient Combination of Two Fasteners

A new fastener for the aerospace industry.

The HITSERT® Screwlock combines the advantages of an aluminium HITSERT® 2 and a stainless steel HELICOIL® Screwlock thread insert for screwed connections with high requirements.

These two elements match perfectly to provide considerable benefits for screwed connections with high requirements. Locking of the screw is achieved with a polygonal-shaped thread of the HELICOIL® Screwlock. These threads have a locking effect on the flanks of the screw or bolt to be screwed in. The result is an elastically resilient frictional locking mechanism with the bolt or screw resisting self-loosening and unscrewing.
