## Description

Jam nuts are low-profile nuts that are half as tall as a standard hex nut. It's often used as a type of locknut where it is jammed up against a standard nut to lock the two in place. Perfect for general applications, you can also use it where a standard nut would not fit. Stainless steel fasteners for superior corrosion resistance.

• Thinner version of a standard full hex nut
• Use as a primary nut along with a heavy or finished hex nut
• Used when a nut needs to be locked in place without clamping
