Stainless Steel Hex Thin Jam Nuts

These nuts are half the height of standard hex nuts, and have closely spaced threads to prevent loosening from vibration. They are not compatible with coarse threads. Use them to fasten most machinery and equipment.

Also known as jam nuts, they can be used in place of standard nuts when height clearances are tight, or threaded together to form a locknut. When fastening threaded rod, you can use two nuts to create a point for tightening the rod into place with a wrench. These nuts have less tensile strength than a standard hex nut when used alone.

All meet ISO or DIN standards for dimensions and material composition to ensure compatibility with other products and tools. DIN 936 and DIN 439B standards are no longer active, but they are commonly referenced globally.

Steel nuts without a plating are best for dry environments, since exposure to moisture and chemicals will cause them to rust.

Zinc- and zinc yellow-chromate plated steel nuts resist corrosion in wet environments.
