Zhuocheng DIN7967 self locking nut pal nuts

Palnut Regular Lock Nuts secure bolts in applications where vibration or dynamic load might cause them to become loose.
These Palnut Regular Lock Nuts are a cost effective solution. They are inexpensive and do not require a torque wrench to install them, so installation is quick and easy. The installer turns the Lock Nut to finger tight then uses a spanner to tighten them a further third to half a turn. Once properly tightened, the hex face becomes slightly concave. This means they can be checked with a simple visual inspection which is less expensive than other Lock Nut systems.

Under M5 they can be used alone, for M6 and above they must be used in conjunction with a regular full nut.
