Product Description

Leader-Fastener® DIN 439 Hex Nut are thin hexagonal jam nuts with a thickness of 0.5 x diameter. A hex jam nut is a low-profile type of hex nut, typically about half as thick as a regular hex nut. It is often used as a lock nut, where it is threaded up against a standard nut locking it in place. Also in circumstances where a standard nut is too thick for an application, a hex jam nut can be a very useful alternative. Metric DIN 439 thin hex jam nuts are available unchamfered (Type A) and chamfered (Type B). These nuts are offered in in both right hand and left hand thread and in steel, brass as well as stainless steel A2 and A4.
