Starrett 435ME-300 Engineers Combination Square Set

The Starrett 435ME-300 Engineers Combination Square Set is a precision measuring and marking tool designed for metalworking, engineering and general fabrication tasks. This professional-grade 300mm (11¾ inch) combination set features a hardened steel blade with photo-engraved graduations, ensuring long-lasting accuracy and clarity even in demanding workshop environments.

The set includes three interchangeable heads – a square head, centre head and reversible protractor head – all mounted on a single graduated blade with a reversible lock bolt for secure positioning. Both the square head and protractor head incorporate spirit levels for checking horizontal and vertical alignment, whilst the protractor features a direct reading double 180-degree scale for accurate angle measurement. The cast iron heads have a durable black wrinkle finish that resists wear and corrosion.

Ideal for precision layout work, quality control inspection and workshop fabrication, this combination square set provides versatile measurement capabilities in a single compact tool. The blade offers dual graduations on each side – 1/2mm and 32nds on one side, with mm and 64ths on the reverse – making it suitable for both metric and imperial working. A scriber is included for accurate marking out on metal surfaces.
