A jam nut is a type of low profile nut, usually about half as tall as a regular hex nut. It is most commonly used as sort of a locking nut, where it is "jammed" up against a regular nut to lock it into place. It is also used in situations where a standard nut is too large to fit.
These jam nuts are TRUE TITANIUM(TM), specifically Grade 5 (6Al-4V) Titanium, and are 44% lighter than stainless steel. TRUE TITANIUM(TM) jam nuts will remain corrosion free in the natural environment, making them the perfect forget it and forget it'? material for any fastener used where corrosion and/or strength are an issue.
