Starrett 56394 Combination Square Set 6 Inches 2 Piece

Product Description

The STARRETT 56394 is a 2-piece combination square set built for layout, measurement, and inspection work in the trades. The set includes a 6-inch steel blade and a forged steel square head. The blade is graduated in the 16R style, offering four graduation increments: 1/32, 1/64, 1/100, and 1/50 inch. This combination square is used by machinists, pipefitters, electricians, carpenters, and general tradespeople who need a reliable, compact layout tool for scribing, checking 90-degree angles, and measuring depth or height off a surface.

This set is suited for both shop and field use. The 6-inch blade length makes it practical for close-quarter layout work on conduit, pipe, structural steel, or millwork. The forged steel square head locks onto the blade and can be repositioned along its length, allowing the tool to function as a try square, miter square, depth gauge, or scribe. It is a standard trade-shop tool appropriate for residential and light commercial applications alike.

Installation Notes

No power source or electrical shutoff is required for this hand tool. Before use, verify that the head lock is fully tightened to prevent blade movement during measurement. Inspect the blade edge and head face for burrs or damage that could affect reading accuracy. Calibration checks against a known reference surface are recommended when precision layout work is required.
