Starrett 51143 Hermaphrodite Caliper 6 Inch Leg

Product Description

The STARRETT 51143 is a hermaphrodite caliper with a 6-inch leg, designed for layout and scribing work in metalworking and fabrication. One leg is a standard caliper leg while the other terminates in a scriber point, allowing the tool to locate center points, scribe lines parallel to an edge, or transfer measurements from a reference surface. The firm joint maintains the set position under working load, and the knurled nut allows for precise leg adjustment. The tool is constructed from steel with a polished finish. It is a hand-measurement tool used by machinists, pipefitters, and fabricators on the bench or in the field.

This caliper is suited for layout tasks in machine shops, fabrication shops, and industrial maintenance environments. Common applications include scribing a line at a consistent offset from a workpiece edge, stepping off measurements, and locating shaft centers. The 8-inch maximum measurement capacity and round leg profile make it practical for both flat-stock and curved-surface work. It is a standard bench tool found in trade and industrial settings wherever precision hand layout is required.

Key Features

• Firm joint design holds set position under working load without slipping
• Knurled nut adjustment for controlled, repeatable leg spacing
• 6-inch leg length with 8-inch maximum measurement capacity
• Round leg profile suitable for flat stock and curved surfaces
• Steel construction with polished finish for corrosion resistance and durability
• Hermaphrodite configuration for scribing, center-finding, and edge-offset layout

Compatibility

Designed as a standard hermaphrodite caliper for general layout and scribing applications in metalworking, fabrication, and industrial maintenance. No specific system or equipment compatibility is required for this hand tool.

Installation Notes

This is a hand layout tool and does not require installation. Before use, inspect the scriber point and caliper leg for damage that could affect measurement accuracy. Adjust leg spacing using the knurled nut and verify the set measurement against a rule before scribing. Store in a dry location to protect the polished steel finish from corrosion.
