Mil. Spec. Hex Nuts

These nuts are manufactured and tested to strict U.S. military standards for material and construction.

Low-Strength Steel

Image of Product. Front orientation. Hex Nuts. Mil. Spec. Hex Nuts.

Rated Grade 2, Class 6, or lower, these nuts are about half as strong as medium-strength nuts. They are suitable for light duty fastening applications, such as securing access panels. Use them with screws that have a similar strength rating to avoid stripping threads during installation.

Cadmium Yellow-Chromate-Plated Steel— The plating creates a barrier against rust, so these nuts are suitable for most wet and outdoor environments. They also thread on smoothly without sticking.
