Zoro Select Carriage Bolts Chrome 7/16-14

These Zoro Select carriage bolts come in a pack of five with a chrome-plated finish. They are made from Grade 5 medium carbon steel for general fastening tasks. The square neck design prevents rotation during installation in wood or metal. They suit DIYers and tradespeople needing a corrosion-resistant inch-series bolt.

Grade 5 Tensile Strength 120000 psi

The critical specification is the Grade 5 rating with a tensile strength of 120000 psi. This defines the load the bolt can handle before failure. The coarse UNC thread pitch of 14 threads per inch matches standard nuts. Verify that your application requires Grade 5 strength rather than a lower or higher grade.

Pack of Five One-Inch Length

The pack contains five bolts each measuring one inch in length with a 7/16 inch diameter. The round head diameter is .907 in and the square width is .431 in. They fit a 29/64 in drill hole and meet ASME B 18.5 standards. Buyers needing longer lengths, larger diameters, or bulk quantities will need a different product.

Questions about this item

What does the 120,000 psi tensile strength mean once the bolt is installed?

It indicates the bolt can withstand high clamping loads in structural joints before stretching or breaking, suitable for Grade 5 applications.

How does the UNC coarse thread affect fit with mating hardware?

The 7/16-14 UNC thread matches standard coarse nuts and tapped holes, allowing faster assembly and better resistance to stripping in softer materials.

What clearance and drill size are needed for the square neck and shank?

Drill a 29/64 in hole for the shank; the 0.431 in square neck seats into the same hole to prevent rotation during tightening.
