Class 8 nuts are comparable in strength to Class 8.8 bolts and are suitable for fastening most machinery and equipment.

About half the strength of medium-strength steel nuts, these nuts are for light duty fastening applications.

These nuts tighten when turned to the left; once fastened, they resist loosening from counterclockwise motion. Made of Grade 2 and Class 04 steel, these nuts can be used for fastening panels and other light duty fastening applications.

These nuts have good chemical resistance and may be mildly magnetic.

Also known as small-pattern hex nuts, these are about 20% narrower than standard hex nuts for use in tight spaces where standard hex nuts won't fit.

About half the strength of medium-strength steel extra-wide hex nuts, use these nuts for light duty fastening applications, such as securing access panels.

About half the strength of medium-strength steel flange locknuts, these are for light duty fastening applications, such as securing access panels.

These flange locknuts are comparable in strength to Grade 8 bolts.

About half the strength of medium-strength steel flange nuts, use these metric nuts in light duty fastening applications, such as securing access panels.

The nut head rotates while the flange remains stationary to prevent scratching the material surface as you tighten the nut.

Includes inch thread sizes. These Grade 8 steel locknuts are 25% stronger than our medium-strength steel nylon-insert locknuts.

These Grade 8 locknuts are about three times stronger than low-strength steel distorted-thread locknuts.

Comparable in strength to Grade 8 bolts, these locknuts are about 25% stronger than medium-strength steel locknuts.

These locknuts have a curved washer that acts as a spring for easy installation and mild vibration resistance. The smooth rim makes them less likely to scratch materials when tightened than locknuts with a tooth lock washer.

Threads at the top of these locknuts expand to grip the bolt on all sides for a stronger hold than distorted thread locknuts.

For light duty applications, choose these metric-sized coupling nuts.

A flange distributes the load over a large area and reduces stress where the nut meets the material surface.

These nuts can be tightened with a wrench once positioned by hand.

These nuts have a black-oxide finish for mild corrosion resistance in dry environments.

Need to join two female-threaded parts, such as coupling nuts, with dissimilar inch thread sizes? Attach them to these adapters and tighten the exterior hex nut for a secure connection.

Twist these adapters onto female metric threads to change pitch or switch thread sizes.

Increase or decrease metric thread size from one male-threaded part to another. Commonly used to connect two differently sized threaded rods, they have a hex-shaped body, so you can tighten them with a standard wrench.
