Application

Hex nuts are a six‑sided nut and are the most commonly shaped nut today. They are used with anchor shackles, bolts, screws, and other externally threaded components. Hex nuts, in conjunction with these other fasteners, are used to connect both metal and wood components to prevent tension and movement.

Use a hex nut with a screw or hex head bolt to fasten two or more wood or metal parts. Hex nuts are often used in construction for framing or to create a bolted joint. Nylon nuts are nonconductive and offer corrosion resistance and lasting hold at a low cost. A jam nut can be used to lock a standard nut in place when it is not tightened against another surface

Hex Nut Bolt Grade C nuts are used for machines, equipment, or structures with rough surfaces and low precision requirements; Grade A and B nuts are used for machines, equipment, or structures with relatively smooth surfaces and high precision requirements

Frequently Asked Questions

What is the difference between a standard hex nut and a heavy hex nut? A standard hex nut, also referred to as a finished hex nut, has a smaller width across the flats and corners compared to a heavy hex nut, and a heavy hex nut is slightly thicker than a standard hex nut of the same nominal size.

The 2H hex nut is a specially designed medium carbon steel fastener falling under the ASTM A194 standards, and should only be used in applications where the advantages are fully realized. The 2H hex nut bears a clear mark on the fastener face, indicating the grade (2H).

The jam nut essentially acts as the “other object”, as the two nuts are tightened against each other. They can also be used to secure an item on a fastener without applying force to that object. This is achieved by first tightening one of the nuts onto the item.

Nylon insert lock nuts—also known as nylon nuts and stop nuts—are a prevailing torque, locking nut that resists loosening caused by vibration and normal use. Unlike free-spinning hex nuts, lock nuts make use of a deforming elastic or metal material to stay in position against torque and shock

Hex Flange Nuts are hex nuts with a wide flanged portion near one end that acts as an integrated non-spinning washer. Flange nuts are used to spread the load placed on the nut over a wider surface area to prevent damage to the installation material

Hexagonal nuts are generally made from steel that has been specially cut with the help of a steel cutting machine. The entire process is relatively quick, and thousands of nuts can be produced within a matter of minutes.brass, copper, stainless steel, titanium, aluminum is also can make hex nut
