Hex Bolt 1" x 7 1/2"-8 TPI 307A PX Grade A Black Oxide NOS Nut & Washers 176H

Hex bolts are one of the most common fasteners and can be used in a wide variety of applications. The 6 sided head makes them easy to install using a standard wrench or socket tool. Nuts and washers are not included, so will need to be purchased separately. Washers help to evenly distribute the load and should always be used under the bolt head and under the nut (just under the bolt head if installing into a threaded hole). Flat washers and finished/standard hex nuts work great for most applications, though if the bolt may be subject to excessive vibration, it is recommended that lock washers and lock nuts be used instead.

Hexagonal heads and machine threads used with a nut or in a tapped hole; also known as or machine bolts. Hex bolts are similar to hex cap screws.

What is the difference between a hex cap screw and a hex bolt? A hex cap screw has tighter tolerances on the body dimensions and features a chamfered end and a washer face under the bolt head. A hex cap screw is often called a finished hex bolt. Hex bolts have a flat end and lack the washer face under the head. Hex bolts may have an undersize body in longer lengths.
