JR and JRL Screws for Pipe Clamps

The JR and JRL screw is designed for securing pipe clamps — for their reliable fixation and tightening. The fastener is a metal rod with double thread, the configuration of which differs depending on the version. The product is also used for driving into wood and wood-based materials or for installation into plastic wall plugs in concrete walls.

Design and application features

Depending on the version, the driving method differs:

• JR screws are fitted with an internal star-shaped recess for driving with a Torx key.
• JRL screws are fitted with a flange and a slot for driving with a flat-blade screwdriver.

Both versions use zinc-plated steel, with the zinc coating applied by electroplating. The material has increased corrosion resistance, so the product is suitable for use in high-humidity conditions.

This type of fastener is used for installing PPC and PPL pipe clamps — in construction and plumbing work.
