Also known as jam nuts, these are about half the height of standard hex nuts. Use in low-clearance applications or jam one against a standard hex nut to hold it in place. They're about 25% stronger than medium-strength steel thin hex nuts.

Zinc yellow-chromate-plated steel nuts are more corrosion resistant in wet environments than zinc-plated steel nuts.

Also known as jam nuts, these are about half the height of standard hex nuts. Use them in low-clearance applications or jam one against another nut to hold it in place. About half the strength of medium-strength steel thin nuts, use them for light duty fastening applications, such as securing access panels. Some of these screws meet ISO and DIN dimensional standards.

Nuts with fine and extra-fine thread spacing are less likely to loosen from vibration than nuts with coarse thread spacing.

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

Nuts that meet ISO 4035 (formerly DIN 439B) adhere to international standards for dimensions and material composition to ensure compatibility with other products and tools. Although the DIN 439B standards are no longer active, they are commonly referenced globally.
