These locknuts have excellent resistance to chemicals and salt water. They're about half the height of standard nylon-insert locknuts. Use them in low-clearance applications or jam one against a hex nut to hold it in place. The nylon insert grips the bolt to resist loosening without damaging threads. They're reusable, but their holding power lessens with each use. They may be mildly magnetic.

About two-thirds the height of standard flex-top locknuts, use these in low-clearance applications or jam one against a hex nut to hold it in place. Threads at the top of the nut expand to grip the bolt on all sides for a stronger hold than distorted-thread locknuts. The strength of the bolt should match the strength of the nut to prevent damaging threads. These locknuts have equivalent strength to Grade 8 steel locknuts.

Plain steel locknuts are uncoated and ready for painting.

Cadmium-plated locknuts are corrosion resistant in wet environments. The plating adds lubricity so they thread on smoothly.

These 18-8 stainless steel locknuts have good chemical resistance and may be mildly magnetic. They're about two-thirds the height of standard flex-top locknuts. Use them in low-clearance applications or jam one against a hex nut to hold it in place. Threads at the top of the nut expand to grip the bolt on all sides for a stronger hold than distorted-thread locknuts. The strength of the bolt should match the strength of the nut to prevent damaging threads.

Insert a rod or pin into the holes for increased torque while tightening. Use these thumb nuts in low-clearance applications or jam one against another nut to hold it in place. The knurls provide a slip-resistant grip for controlled adjustment. A black-oxide finish provides mild corrosion resistance in dry environments.

These thumb nuts have good chemical resistance and may be mildly magnetic. The flange distributes the load over a large area and reduces stress where the nut meets the material surface. A knurled head provides a slip-resistant grip for controlled adjustment.

Passivated stainless steel nuts provide added protection against oxidation and corrosion.
