National Mfg N130-583 Zinc Bolt Hook 5/8x12 in Gate Hinge

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N130-583 is a full-threaded zinc bolt hook designed for gate hinge applications. Measuring 5/8 inch in diameter and 12 inches in length, it bolts through a post and is firmly secured on each side using standard-size nuts and washers. Two washers and two nuts are included per hinge. The fully threaded shank allows positional adjustment along the bolt length, enabling correction of gate sag without replacing the entire hinge assembly. Licensed contractors and experienced installers handling gate hardware will find this a direct-fit solution for both replacement and new installation work.

This bolt hook is intended for use as a replacement component with National 292 Bolt Hook Strap Hinges or for new installations using National 294 Hinge Straps only. It is suited for residential and light commercial gate applications where a threaded, through-post mounting style is required. The zinc finish provides basic corrosion resistance appropriate for exterior use. Hardware is supplied boxed loose, and the package quantity is 10 units.

Installation Notes

Installation is typically performed by general contractors, fence installers, or experienced maintenance personnel. The bolt passes fully through the gate post and is secured with nuts and washers on each side — ensure the post material is structurally sound and of adequate thickness before drilling. Use appropriately sized hardware tools to snug nuts firmly without over-torquing the zinc-plated hook. Inspect washers and nuts for proper seating before completing the installation.
