Starrett 52610 Telescoping Gage 5/16 to 1/2 in

Product Description

The STARRETT 52610 is a telescoping gage designed for measuring inside diameters, bores, and slots in precision mechanical and trade work. It features a spring-loaded plunger that locks at the measured dimension, allowing the tech to transfer the reading to a micrometer or caliper for a precise measurement. The gage covers a range of 5/16 to 1/2 inch and has an overall length of 3-1/8 inches with a 2-3/8 inch handle. The satin chrome finish reduces glare and resists corrosion in shop environments. Machinists, millwrights, HVAC technicians, and plumbers use telescoping gages when checking bore wear, valve seats, and fitting clearances.

The STARRETT 52610 is suited for residential and light commercial service work where internal diameter measurements are required. It is commonly used when inspecting pump housings, bearing bores, pipe fittings, and valve bodies. The compact 3-1/8 inch overall length allows access to confined spaces. It is a hand tool intended for technicians who already own a micrometer or caliper capable of reading the transferred measurement.

Key Features

• Measurement range of 5/16 to 1/2 inch covers common bore and fitting sizes
• Spring-loaded, lockable plunger transfers measurement accurately to an outside micrometer or caliper
• Satin chrome finish resists corrosion and minimizes reflective glare during use
• 2-3/8 inch handle length provides controlled grip in tight access areas
• Compact 3-1/8 inch overall length suits confined bore inspection locations
• Lightweight at 0.063 pounds for single-hand operation

Compatibility

Designed as a standard telescoping gage for use with any outside micrometer or caliper capable of reading in the 5/16 to 1/2 inch range.

Installation Notes

No installation is required for this hand measurement tool. Before use, ensure the bore or surface to be measured is clean and free of debris that could affect the gage reading. Lock the plunger only after the gage has fully seated and sprung to the bore wall, then carefully withdraw without disturbing the locked position before transferring to the measuring instrument. Handle the gage with care to avoid dropping, which can damage the spring mechanism or affect calibration.
