Frequently Asked Questions

How to select the right hex bolt size for a project?

To select the right hex bolt size, consider the diameter (measured across the shank) and length (from the underside of the head to the tip). The diameter should match the hole size in the materials being joined, with a snug fit to prevent wobbling. The length should be sufficient to pass through all materials and engage fully with a nut (typically 1-1.5 times the diameter of threads beyond the nut). Also, consider the thread type (coarse or fine) based on the application—coarse threads are stronger in wood, while fine threads provide better holding in metal.

Ryan Taylor

These hex bolts are my go-to for all construction jobs, from framing to installing fixtures. The Grade 5 steel provides enough strength for most residential projects, and the zinc coating prevents rust in damp basements. I appreciate the variety of sizes in the bulk pack, which covers everything from 1/4" to 3/4" diameters. The hexagonal heads fit standard wrenches and sockets, making installation quick, and the coarse threads grip wood and metal equally well. For a reliable, all-purpose fastener, these hex bolts deliver consistent performance at a reasonable price.
