Sterling Combination Square Rule 600mm Metric
Many have combination squares, they are usually second-hand or heirlooms that have been passed down in the family. In many instances, the rules are corroded and treatments to remove the rust leave them shiny and more difficult to read. Sterling Tool Works is now offering Premium replacement rules that are precision made in the USA. The rules are chemically etched, etchings blackened, tempered and satin chrome plated for an excellent resolution that is easy on the eyes.
A 600mm rule can be extremely useful for larger tasks in the shop and are a TREMENDOUS value at this price. Give your vintage Combination Square an upgrade with a new rule! Available in Metric graduations; .5mm, 1mm.
Note: We cannot guarantee that the rules will fit ALL vintage square heads, I have tested with several different makers and vintages that I have on hand and all have worked. The critical dimensions to verify if these will work are:
Thickness = Sterling Rules are .088" Thick
Width Edge to Groove = .46"
Groove width = .093"
