Spi CMS170309011 Vernier Caliper 0-6 in Stainless Steel

Product Description

The SPI CMS170309011 is a stainless steel vernier caliper designed for precise dimensional measurement in trade and industrial applications. It covers a measurement range of 0 to 6 inches (0 to 150 mm) with an accuracy of 0.001 inches and an inch graduation of 0.001 inches (0.02 mm metric graduation). The 1.57-inch jaw depth accommodates a range of workpiece geometries. This tool ships calibrated with NIST traceability certification included, making it ready for use in quality-controlled environments. A fine adjustment mechanism allows controlled, repeatable positioning of the sliding jaw for accurate readings.

This vernier caliper is suited for use in machine shops, HVAC fabrication, plumbing rough-in, and field measurement tasks where precise inside, outside, depth, and step dimensions are required. The stainless steel construction resists corrosion in damp or shop environments. It is an appropriate tool for licensed tradespeople, inspectors, and shop technicians who need calibrated measurement documentation. Each unit includes a protective case for storage and transport.

Installation Notes

No installation is required for this hand tool. Before use, verify the caliper reads zero with the jaws fully closed and confirm the NIST calibration certificate is within your facility's recalibration interval. Handle the stainless steel measuring faces carefully to avoid nicks or burrs that can affect accuracy. Store in the included case when not in use to protect the measuring surfaces.
