Telescoping Gauge Set - 5/16 - 6in

The Telescoping Gauge Set - 5/16 to 6 inch Range by COMP CAMS is a precision measurement tool designed for mechanics, machinists, and engine builders who require accurate bore and hole sizing across a broad range of diameters. This set is an efficient choice for both professional shops and serious hobbyists working on engine blocks, cylinder heads, and precision machine work.

Telescoping gauges operate by expanding an internal contact arm to precisely match the inner diameter of a hole or bore, then locking in place and measuring against an external micrometer or caliper for exact dimension confirmation. The 5/16 to 6 inch range covered by this set's gauges eliminates measurement gaps and provides continuous coverage for the most common sizes encountered in automotive and machine work.

This set is ideal for engine builders verifying OEM specifications, machine shops performing quality control inspections, and technicians restoring classic vehicles. Its versatility and repeatability are essential to quality workmanship in demanding production and restoration environments.
