The VALUE COLLECTION SS/4-6-9-12/ST is a four-piece square set designed for layout, inspection, and scribing work across metalworking, fabrication, and general trade applications. The set includes four squares with blade lengths of 4, 6, 9, and 12 inches and corresponding base lengths of 3, 4, 6-9/32, and 8-1/4 inches. Constructed from steel, these squares deliver the rigidity and durability required for shop-floor and field use. The set ships as a single package and is suited for machinists, fabricators, pipefitters, and maintenance technicians who need a range of square sizes on hand.
This set covers a practical range of blade lengths, making it useful for tasks that require checking right angles on small components as well as larger workpieces. The included sizes allow a single technician to carry one kit rather than sourcing individual squares. Typical applications include layout work on structural steel, verification of machined surfaces, and general squareness checks during equipment installation or repair. The set is appropriate for both shop and field use in industrial, HVAC, plumbing, and mechanical trades.
Designed as a general-purpose steel square set for layout and inspection use across metalworking, fabrication, and mechanical trade applications.
Squares are hand tools and do not require installation. Technicians should inspect each square for burrs or damage before use to ensure accurate readings. Store squares in a protective case or pouch when not in use to prevent edge damage that could affect measurement accuracy. Periodic verification against a known reference surface is recommended to confirm continued squareness.
