MIDWEST FASTENER CORP 52291 1/4"-20 x 2-5/16" Zinc Plated Steel Coarse Thread J-Bolt

Hardware for structural anchoring

The MIDWEST FASTENER 52291 is a zinc-plated steel J-bolt with a 1/4"-20 coarse thread and a 2-5/16" shank. It is designed for builders and maintenance crews who need a formed hook to anchor cables, pipes or light fixtures to concrete, wood or steel structures. The hot-dip coating resists corrosion in damp or outdoor environments. This fastener suits new construction and retrofit projects alike.

Fits a quarter-inch nut and washer

The coarse thread accepts any standard 1/4"-20 hex nut, allowing a single spanner size on site. No specialised driver or adhesive is required, so installation proceeds with basic hand tools. The open hook frees the installer from threading the bolt through a closed eye, speeding up alignment on overhead runs. It works with timber, masonry anchors or welded tabs.

Holds under steady tension

Under sustained load the zinc plating maintains its bond to the steel substrate, preventing red rust from creeping along the threads. The formed hook distributes force across the curve rather than concentrating it at a sharp bend. Coarse threads resist vibration loosening better than fine pitch when the assembly flexes daily. It is not intended for dynamic shock loads or critical overhead lifting.
