Spi 13-632-5 Square Set 3 Piece Hardened Spring Steel

Product Description

The SPI 13-632-5 is a 3-piece square set designed for precision layout, inspection, and verification work in trade and industrial settings. The set includes squares with base lengths of 2 inches, 2-1/2 inches, and 3 inches, paired with blade lengths of 2 inches, 3 inches, and 4 inches respectively. Constructed from hardened spring steel, each square is built to maintain parallelism and straightness under repeated use. This set is suited for machinists, pipefitters, sheet metal workers, and other trades requiring accurate 90-degree reference during layout or quality checks. The full set weighs 6 pounds.

This square set is used in fabrication shops, machine shops, and field service environments where consistent right-angle references are needed across multiple material thicknesses or part sizes. The three included sizes allow a technician to select the most appropriate blade length for the workpiece at hand, reducing the need for multiple individual squares. Applications include checking squareness of assemblies, scribing layout lines, and inspecting machined surfaces.

Key Features

• 3-piece set with base lengths of 2 inches, 2-1/2 inches, and 3 inches
• Blade lengths of 2 inches, 3 inches, and 4 inches
• Hardened spring steel construction for durability and wear resistance
• Manufactured to parallelism and straightness tolerances
• Compact sizing suits both bench and field inspection tasks

Compatibility

Designed as a general-purpose precision square set suitable for layout and inspection applications across fabrication, machining, and mechanical trade environments.

Installation Notes

No installation is required for this tooling set. Store squares in a protective case or pouch when not in use to prevent edge damage that could affect accuracy. Periodically verify squareness against a known reference surface. Handle with care to avoid drops that may compromise the hardened steel geometry.
