150PSI NPT BSPT Low Pressure screw Pipe Fittings For Lock Nut
150PSI NPT BSPT LOW PRESSURE THREADED PIPE FITTINGS FOR LOCK NUT
CLass 150 Hex. lock nuts feature a deforming elastic or metal material that fortifies the secured threaded position to resist torque
and shock. Lock nuts with nylon inserts are a popular solution for many applications; however, they are limited to applications
exposed to temperatures under 250. Lock nuts are most commonly available in ASTM A563 Grades A and DH and
ASTM A194 Grade 2H. They are manufactured with a standard hex or a heavy hex pattern.
Locking Nuts are commonly used with any male fastener with the same thread diameter and pitch,
used to mate a stack or single part together.
