Value Collection ID/12 Inside Caliper 12 Inch Leg

Product Description

The VALUE COLLECTION ID/12 is a spring-joint inside caliper designed for precise internal measurement in machining, fabrication, and inspection applications. Built with a flat steel leg and a polished finish, this caliper handles inside diameter and bore measurements up to 12 inches (300mm). The spring-joint mechanism maintains consistent leg tension during measurement, while the quick nut adjustment allows for fine, controlled positioning without slipping. At 0.48 pounds, it is light enough for extended hand use. This tool is suited for machinists, tool-and-die workers, and quality control technicians working with manual measuring instruments.

The ID/12 is used when measuring inside diameters, slots, grooves, and bores where calipers with flat legs provide better contact and clearance than bow-leg designs. Typical applications include checking bearing bores, cylinder diameters, and machined pockets in both job-shop and production-floor environments. The 12-inch leg length makes it practical for measuring larger internal features that shorter inside calipers cannot reach.

Key Features

• Spring joint maintains consistent leg tension for repeatable measurements
• Quick nut adjustment enables fine, precise leg positioning
• Flat leg design improves contact in tight bores and slots
• Polished steel construction resists corrosion and wear
• Measures up to 12 inches (300mm) inside diameter
• Lightweight at 0.48 pounds for extended use comfort

Compatibility

Designed as a standard inside caliper for general-purpose manual measurement tasks in machining, inspection, and fabrication settings where a 12-inch leg spring-joint inside caliper is required.

Installation Notes

No installation is required for this hand tool. Before use, verify the caliper legs are clean and free of burrs that could affect measurement accuracy. When adjusting, use the quick nut to set leg spread and confirm the reading against a known reference standard before measuring production parts. Store with legs protected to prevent damage to the polished contact surfaces.
