Machinist Square 3" (95 mm X 75 mm)

A machinist square is the metalworker's equivalent of a woodworker's try square. The term square refers to the tool's primary use: measuring the accuracy of a right angle (90 degrees). To try a surface is to check its straightness or its correspondence to an adjoining surface—a fundamental task in precision metalworking, benchwork, and fabrication.

This 3" machinist square measures 95 mm x 75 mm and features a small notch cut into the inside corner. This notch prevents fine particles and debris from accumulating at the corner junction, which could otherwise lift the square off the workpiece and compromise the accuracy of the reading.

Features

• Checks and verifies 90-degree right angles on metal workpieces and surfaces
• Inside corner notch prevents particle buildup that could affect measurement accuracy
• Compact 3" size suited for benchwork and detail-oriented metalsmithing tasks
• Functions as a try square for checking surface straightness and adjoining surface correspondence

Specifications

Notes

• Keep the square clean and free of debris, particularly at the inside corner, to maintain accurate readings.
• Handle with care—dropping or impacting the square against hard surfaces may alter its calibration.
