The NATIONAL MFG/SPECTRUM BRANDS HHI N130-674 is a fully threaded zinc bolt hook designed for gate hinge applications. Measuring 0.75 inches in diameter and 12 inches in length, this bolt hook passes through a gate post and is secured on each side with standard nuts and washers. It serves as a replacement component for National 292 Bolt Hook Strap Hinges and is also suitable for new installations using National 294 Hinge Straps. The full-thread design allows for incremental adjustment to correct gate sag over time. Each unit ships boxed loose and includes 2 washers and 2 nuts per hinge. Sold in a package quantity of 10.

This bolt hook is intended for residential and light commercial gate installations where a reliable, adjustable hinge pivot point is required.

Drill a clean through-hole in the post sized to accept the 0.75-inch bolt shank, insert the hook, and secure with the supplied nuts and washers on both sides. Tighten fasteners with standard wrenches; do not overtighten to the point of compressing or splitting wood post material.
