Product Description

Nut-Hex 5/16-18 Specifications

This hex nut is a fastener made from steel and is used to secure the end of a bolt in various lawn and garden equipment and machinery. It is a genuine OEM replacement part that comes in a standard size of 5/16 of an inch with 18 threads per inch. The hex nut has a hexagonal shape, which gives it greater grip and makes it easy to tighten using a wrench or a set of pliers. The nut also has a flange on one end, which locks the nut in place, prevents damage to the area where it is installed, and allows the load to be evenly distributed. It is important to replace your hex nut if it is loose, cracked, or corroded. If you have not yet removed the old hex nut from your equipment you will need a socket wrench to remove it. After that, you can easily install the new nut by threading it onto a bolt or screw and then tightening it with a wrench or pliers until it is tightly secured.
