Hex nuts are the most versatile nuts, and can be used for a variety of applications

 
If you're in need of a fastener for a bolt, consider a zinc plated hex nut. These nuts are available in different strength grades. SAE, or the Society of Automotive Engineers, grades nuts for their strength. Grade 2 is the least expensive, followed by Grade 5 and Grade 8. These nut grades are identified by markings on the surface. Not all nuts have the same strength grade, and a plain finish steel nut can rust and corrode.

Hex nuts are available in brass, zinc plate. They are available with lock washers to secure them. Hex nuts are available in standard right-hand threads and have Unified inch coarse and fine series threads. Some sizes are left-hand threaded. These nuts are available in various sizes and grades. When purchasing hex nuts, be sure to know which size you need.

Hex nuts are the most versatile nuts, and can be used for a variety of applications. To avoid corrosion, use them with heat-treated and low-carbon bolts. The weight of a zinc-plated hex nut is an indication that it is made of a larger casting than others. It is also important to note that ASTM A194/A194M graded hex nuts meet the thread requirements of ANSI B1.1. They are commonly zinc-plated for increased strength and resistance to rust in normal atmospheric conditions.

Hex nuts are commonly used for fastening screws and bolts. The hexagonal shape of these nuts makes them easy to use and can be purchased in a variety of sizes. Hex nuts are often used in combination with jam nuts, which are used to secure two nuts together. Often, hex nuts are used in construction settings, but there are also many uses for jam nuts. The jam nut is used to fasten two nuts together. They lock together when tightened.
