These nuts are suitable for fastening most machinery and equipment.

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 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.

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

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

Known for their strength, these steel cap nuts have a black-oxide finish to resist corrosion in dry environments.

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

Use these thumb nuts in low-clearance applications or jam one against another nut to hold it in place.

Knurls provide a slip-resistant surface for controlled adjustment.

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.

Adapt threaded rods from inch to metric. These adapters connect two male-threaded fasteners, so you can change the gender of a mating part or increase or decrease its thread size. The hex-shaped body fits into the head of a standard wrench.

Connect two differently sized male-threaded parts, such as threaded rods, and tighten with a standard wrench.
