Heavy Hex Nuts

Heavy Hex Nuts

Heavy hex nuts are wider, taller, and thicker than regular hex nuts to provide additional strength and increased lifespan. Their increased size provides larger bearing surfaces for tools and thread engagement.

Machine Screw Hex Nuts

Machine Screw Hex Nuts

Machine screw hex nuts fasten onto machine threaded fasteners in low-to-medium load applications. They are generally used for male fasteners that are less than 3/4 inch in diameter with uniform threads throughout their length.

Panel Hex Nuts

Panel Hex Nuts

Panel hex nuts are thinner and much shorter than regular hex nuts. They mate with male-threaded components that insert through flat surfaces and secure them into place.

Jam Hex Nuts

Jam Hex Nuts

Jam nuts tighten against the main fastening nut to prevent unwanted rotation. They are generally half the height of regular hex nuts and sometimes thinner for the same inner diameter.

Acme Hex Nuts

Acme Hex Nuts

Acme hex nuts are designed to mate with acme-styled threads to provide a strong, durable fastening solution. The acme thread design is larger and tougher than conventional threads, making it ideal for high-load applications.

Hex Nut Assortments

Hex Nut Assortments
Hex nut assortments contain matching nuts and washers in a variety of sizes. They are commonly used in manufacturing due to the repeated use of the same fasteners.
