Starrett 50528 Vernier Caliper 0-24 in Steel

Product Description

The STARRETT 50528 is a heavy-duty vernier caliper designed for precision outside and inside measurement across a full 0 to 24 inch range. Built from steel with a satin chrome finish, it delivers an accuracy of 0.0005 inches and reads in 0.001 inch graduations, making it a reliable instrument for dimensional inspection, layout work, and quality control in trade and industrial settings. The caliper features a fine adjustment mechanism for controlled slide movement and double set screws for positive locking. Jaw depth measures 2.3125 inches. A protective case is included for storage and transport.

The STARRETT 50528 suits applications where large-diameter or long-dimension verification is required. It is commonly used by machinists, pipefitters, millwrights, and mechanical contractors working on shafts, flanges, housings, and structural components that exceed the range of standard 6 or 12 inch calipers. The 24 inch capacity makes it appropriate for industrial fabrication, HVAC ductwork dimensioning, and mechanical equipment inspection tasks where a shorter caliper cannot reach.

Key Features

Compatibility

Designed as a standalone precision measuring instrument; compatible with standard vernier caliper workflows requiring a 24 inch capacity range in steel construction.

Installation Notes

Vernier calipers require no installation. Technicians should zero the caliper before use and confirm the sliding jaw moves freely without play. Keep the measuring faces clean and free of burrs or debris before taking readings. Store the caliper in the included case when not in use to protect the measuring surfaces and maintain calibration integrity.
