Value Collection OD/6 Outside Caliper 6 Inch Spring Joint

Product Description

The VALUE COLLECTION OD/6 is a spring-joint outside caliper designed for direct measurement of outside dimensions on round stock, tubing, and machined parts. The tool features a flat leg profile with a quick nut adjustment, allowing the technician to set and lock a measurement position with one hand. The legs are manufactured from steel with a polished finish for corrosion resistance and smooth jaw contact. Maximum measurement capacity is 6 inches (150 mm). At 0.22 pounds, the caliper is light enough for continuous use during layout and inspection work without hand fatigue.

This outside caliper suits machinists, toolmakers, pipefitters, and maintenance technicians who need a simple, reliable transfer-measurement tool. It is well suited to manual layout work, inspection of turned parts, checking pipe and bar stock diameters, and any application where a direct-reading transfer caliper is preferred over a digital instrument. The spring joint maintains consistent jaw tension across the measurement range, reducing slip during transfer to a steel rule or micrometer.

Key Features

• Spring joint design maintains consistent jaw tension without manual pre-loading
• Quick nut adjustment for fast, repeatable measurement locking
• Flat leg profile for accurate contact on curved and flat outside surfaces
• Polished steel construction resists corrosion and provides smooth jaw action
• 6 inch (150 mm) maximum measurement capacity
• Lightweight at 0.22 pounds for extended use during layout and inspection

Compatibility

Designed as a general-purpose outside caliper for use in machine shop, pipe fitting, and maintenance applications where transfer measurement of outside dimensions is required.

Installation Notes

No installation is required for this hand tool. Before use, verify the caliper legs close fully to zero without gap and that the quick nut holds adjustment without drift. When transferring a measurement to a rule or micrometer, keep the caliper perpendicular to the reference surface to avoid parallax error. Periodically clean and lightly oil the spring joint to maintain consistent tension.
