Hot Dip Galvanised Palnut Regular Lock Nuts offer corrosion resistance up 1,000 hours of salt spray. This makes them suitable for outdoor use like electricity pylons. Because the galvanisation adds a layer to the surface of the Lock Nut they are made slightly oversize so they still spin freely on to the bolt.
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.
