Sealey MGM1 Multi Gauge Metric

The Sealey MGM1 Multi Gauge Metric is a stainless steel multifunction measuring tool designed for rapid thread identification and component measurement on site. This compact gauge enables tradespeople to quickly identify bolt sizes, select the correct drill bit or tap, and verify component dimensions without returning to the workshop.

Manufactured from durable stainless steel, this metric gauge provides thread pitch identification from 0.5mm to 3mm and covers bolt screw diameters from M3 to M20. The integrated tap and drill recommendation guide helps you select the correct tooling for threading operations, whilst the wire gauge function verifies conductor diameters from 0.8mm to 2.5mm.

The tool functions as a set square with pre-marked angles at 15°, 30°, 45°, 60° and 90°, and incorporates a 0-180° protractor for measuring angles. Additional measurement capabilities include a ruler calibrated for bolt lengths up to 7cm and slots for checking washer thickness. This versatility makes the MGM1 ideal for engineers, mechanics and maintenance professionals working with metric fasteners and components.
