Half-Loop Hook Screw

The half-loop hook screw is a fastener made of high-strength round wire. On one side, the straight section of the shank carries a coarse single-start thread ending in a point; on the other, it is bent into a hook or partial loop. The product is designed for screwing into wood or polymer materials. It can also be used as a hanger for storing tools, fixtures, or lightweight equipment. The hook screw is driven in by hand or with a screwdriver or a length of rebar used as a lever.

The material is carbon steel, either plain or with a corrosion-resistant coating. The coating is applied by various methods: galvanic zinc plating, brass plating (combined use of zinc and copper), or coating with durable paints. The fastener’s thread is resistant to mechanical stress, providing high pull-out resistance of the screw from the base material.

Materials:

• Carbon steel
• Coated steel: galvanic zinc plating, brass plating, painting

Dimensions of steel hook screws: screw diameter from 2.15 to 6.0 mm, length from 20 to 100 mm, hook diameter from 10 to 60 mm.
