Hardware Factory Store Hole Gauge Set 5/16″-6″ Carbon Steel Double

Description

Product Overview

The Hardware Factory Store hole gauge set includes six gauges covering 5/16″‑6″ (8mm‑150mm) ranges. Each gauge is forged from high‑grade carbon steel and chrome‑plated for corrosion resistance and long‑term wear resistance. The double‑acting, spring‑loaded mechanism provides constant tension, allowing the gauge to center automatically in the hole for fast, repeatable measurements. Overall dimensions are compact at 7.7 x 6.9 x 0.8 inches, weighing just 10.23 ounces, making storage and transport effortless.

Usage

Designed for precision measurement in factories, educational labs, and repair shops, this gauge set quickly determines the exact size of holes and slots. Expand the gauge inside the target hole, lock it, then read the size with a micrometer or caliper. Its ergonomic handle reduces hand fatigue, making it suitable for prolonged use by technicians, teachers, and hobbyists alike.
