Spi 13-157-3 Dial Thickness Gage 0-0.5 in Range

Product Description

The SPI 13-157-3 is a dial thickness gage designed to measure material thickness across a range of 0 to 0.5 inches (0 to 10 mm). The instrument features a 1.875-inch dial face for clear readability and a 0.5-inch throat depth that allows access to a variety of workpiece profiles. Graduation is 0.01 mm, providing precise incremental readings suited to sheet metal, gaskets, seals, and similar thin materials. This gage is used by HVAC technicians, plumbers, and mechanical tradespeople who need accurate thickness measurement during fabrication, inspection, or quality-verification tasks on the job or at the shop bench.

The SPI 13-157-3 is suited for measuring thin flat materials in residential and light commercial trade applications. Typical use cases include checking sheet metal thickness before cutting or forming, verifying gasket dimensions during equipment repair, and confirming material spec compliance on plumbing or HVAC components. The 0.5-inch throat depth accommodates standard sheet and strip stock encountered in everyday trade work.

Key Features

• Measurement range of 0 to 0.5 inches (0 to 10 mm) covers common sheet and strip stock thicknesses
• 0.01 mm graduation for fine, repeatable readings
• 1.875-inch dial diameter for easy reading in shop and field conditions
• 0.5-inch throat depth allows access to typical workpiece edges and profiles
• Compact form factor suits bench use and portable field inspection

Compatibility

Designed as a general-purpose dial thickness gage compatible with standard sheet metal, gasket stock, and thin flat materials commonly encountered in HVAC, plumbing, and mechanical trade applications.

Installation Notes

No power source is required for this mechanical dial gage. Before use, zero the gage on a known flat reference surface to confirm calibration. Keep the measuring faces clean and free of debris to ensure accurate contact readings. Handle the instrument carefully to avoid dropping, which can affect dial mechanism accuracy and calibration.
