Dies

Dies cut and repair external threads on rod, bolts and studs. This category groups button dies in carbon and HSS, die nuts for chasing damaged threads, die holders like the Sutton 2 inch button die holder, and combination tap and die sets — with the depth sitting in the subcategories below.

It serves fitters and fabricators threading rod to suit, and maintenance crews rescuing bruised bolt threads without replacing the fastener.

Button die or die nut — which do I need?

A button die, split and held in a stocked holder, cuts a new thread from blank rod and allows fine size adjustment. A die nut is hexagonal and driven with a spanner — it's for cleaning up existing damaged threads, not cutting new ones.

WeldCo supplies threading dies to trades across Melbourne and Adelaide through the Tradestore.
