OMEX Machinist Steel Square — 12' (300 mm) A precision, solid industrial square designed to give reliable 90° reference for layout, setup and inspection. Precision ground and hardened steel construction delivers a durable, true right angle for machine shops, fabrication, maintenance and woodworking. Key benefits Confirm true 90° quickly and confidently — removes guesswork when checking parts, fixtures or assemblies. Durable, hardened steel construction resists wear so the reference remains reliable with normal use. Precision ground surfaces provide a flat, straight edge for accurate layout, scribing and inspection. Solid industrial build gives stable contact against surfaces for repeatable measurements and setups. Key attributes Brand: OMEX Type: Machinist steel square, solid industrial design Size: 12 inches / 300 mm Angle: 90° right angle, precision ground Material: Hardened steel Finish: Precisionground working faces for accurate contact How it solves common problems Eliminates uncertain fits: Use the OMEX square to verify squareness of milled faces, welded assemblies and machine setups so parts align correctly before final assembly. Speeds setup and inspection: A reliable reference angle reduces rework by catching misalignment early during layout or machine alignment. Extends service life: Hardened, precisionground steel resists nicks and wear that can degrade accuracy, keeping your measurements consistent. Typical applications Machining and metalworking: Check the squareness of vise jaws, fixture faces, machined parts, and tool setups on mills and drill presses. Quality control and inspection: Provide a quick, accurate 90° reference for go/nogo checks and firstarticle inspection. Woodworking and assembly: Square cabinets, frames and jigs during layout and assembly where a durable rightangle reference is required. Practical notes Use the square on a clean, flat surface and ensure mating faces are of chips, burrs or debris for accuracy. Store flat and protected from impacts to preserve the precisionground faces. Compatible with common inspection and layout tools as a reference for marking, scribing and checking alignment. OMEX precision 12' machinist square provides a straightforward, robust solution when a true 90° reference is required in and industrial settings.
