Metric Steel High Hex Nuts


These nuts are taller than standard hex nuts and provide a larger gripping area for installation with a wrench. They're zinc plated to resist corrosion in wet environments.

Metric Low-Strength Steel Spring-Stop Locknuts—Class 6

These locknuts, also known as Fuji locknuts, maintain their holding power with reuse longer than nylon-insert locknuts. They have a spring ring that creates tension as you tighten the nut, keeping them in place. Yet, their design makes them easy to install and remove. All stand up to high heat and vibration. Zinc plated, they resist rusting in wet or dry environments.

Metric Nylon-Insert Cap Locknuts

A nylon insert on these metric nuts prevents vibration from loosening them, and a domed head protects the threads at the end of the bolt from damage and debris. These nuts are reusable, but the nylon insert’s holding power decreases with each use. Also known as acorn nuts, they create a finished appearance and can reduce snagging on wires and insulation. Nuts meet DIN 986, an international standard for domed cap nut dimensions.
These nuts are made of strong and wear-resistant Class 6 steel. A zinc plating extends the life of the nut by protecting the inner steel from rust.
