Screw Hook

A screw hook is a round steel rod with a coarse-pitch thread cut on one end. The other end has a radial or rectangular bend.

The fastener is made of structural steel, sometimes stainless steel. In the first case, zinc plating is applied for corrosion protection.

Product features

Depending on the hook shape, screw hooks are divided into three types:

• C-shaped (half ring);
• O-shaped (ring);
• L-shaped (screw spike).

The diameter of the wire or rod used as the blank for the screw ranges from 2 to 12 mm, and the overall length of the product is 20 to 400 mm.

Application and installation features

Steel zinc-plated screws with a bent head are designed to be driven into a wooden surface or particle board. Paired with a wall plug, screw hooks are used for mounting into dense, hard substrates — concrete, brick, natural stone. Screw hooks are used to secure various suspended fixtures to walls or ceilings: pictures, light fixtures, frames, mirrors, kitchen cabinets, boilers, radiators. The rod diameter and hook type are selected depending on the weight of the fixture.

Installation of the screw is carried out as follows:

• if the substrate is wood, the product is screwed into a pre-drilled hole or without drilling (taking into account the screw diameter and the hardness of the wood species);
• a concrete or brick wall is drilled, a plastic wall plug is installed, and the screw is then screwed into it.
