Zoro Select MPB760 Carriage Bolt Pack
This pack contains five new carriage bolts made from medium carbon steel with a chrome-plated finish. Each fastener uses a Grade 5 rating and a right-hand UNC thread profile. The square neck design prevents rotation during tightening. They suit general fastening tasks that require this specific diameter and length.
Who These Bolts Fit
Builders needing a 7/16-14 thread size and a 1 3/4 inch length will find the correct dimensions here. The Grade 5 tensile strength of 120,000 psi meets standard structural requirements. Projects requiring a different diameter, thread pitch, length, or a higher grade such as Grade 8 should look at other options. Applications needing stainless steel or a different head style are not served by this pack.
Critical Specification: 7/16-14 UNC Thread
The defining specification is the 7/16-14 UNC coarse thread, which determines nut and tap compatibility. A 29/64 inch drill size matches the shank for proper clearance. The head measures 0.907 inch in diameter with a 0.219 inch height. The square neck width is 0.431 inch and height is 0.219 inch. Verify these figures against your hardware before ordering.

Questions about this item
What size drill bit do I need to pre-drill for the 7/16-14 carriage bolt?
Use a 29/64 in drill bit to create the correct clearance hole for the 7/16 in diameter shank before installation.
Will these Grade 5 bolts work with the Grade 2 hex nuts I already have?
Yes, the manufacturer specifies these bolts are for use with Grade 2 nuts, so your existing hardware is compatible.
How can I confirm the bolt head is seated properly after tightening?
The round head should sit flush with a height of 0.219 in and the square neck of 0.219 in height by 0.431 in width should be fully embedded to prevent rotation.
