Starrett 53124 Vernier Caliper 0-4.75 in Stainless Steel

Product Description

The STARRETT 53124 is a stainless steel vernier caliper designed for precise inside and outside linear measurements in professional trade and light industrial settings. It reads from 0 to 4-3/4 inches with an accuracy of 0.005 inches (0.20 mm), making it a reliable hand tool for technicians who need repeatable dimensional measurements on pipe fittings, housings, ports, and mechanical components. The 1-3/8 inch jaw depth provides reach for stepped or recessed features. A thumb lock secures the sliding jaw once the measurement is set, preventing jaw movement during reading. The bright finish stainless steel construction resists corrosion in field and shop environments.

The STARRETT 53124 is suited for HVAC, plumbing, and mechanical service work where dimensional verification is part of the job. Typical applications include checking pipe OD and ID clearances, measuring component housings, and verifying fit of replacement parts before installation. The 1/4 inch nib size and sliding jaw adjustment make it straightforward to position on irregular surfaces. This caliper is a single-scale vernier instrument — no digital display or dial — which suits users who prefer a tool with no battery dependency and no electronics to protect in the field.

Installation Notes

No installation is required. Before use, verify the jaws close fully to zero and confirm the vernier scale reads 0.000 inches with jaws closed. Keep the beam and jaw faces clean and free of debris for accurate readings. Store in a protective case when not in use to prevent jaw damage and scale wear.
