Question 1

What is the VOLTLOK® Dual-Entry Earthing Nut?

Accepted Answer

A precision-machined brass earthing nut with a full 360° serrated interface, four A2 stainless steel grub screws and a dual-entry conductor design — replacing the drilled hole, crimp lug, banjo washer and ring terminal used in traditional SWA earthing.

VOLTLOK® is available in M20 and M25 thread sizes. Both use the same installation method and same compliance standards.
