Jam Nuts

In stock

Jam Nuts, aslo know as Thin Hex Nuts, are a low profile type of nut. Typically they are half as tall as a standard nut. It is commonly used as a type of locknut, where it is 'jammed' up against a standard nut to lock the two in place or where a standard nut will not fit. These lightweight nylon versions offer a vibration, chemical and corrosion resistant option to metal variants.
