Mitutoyo 510-131 Mechanical Outside Micrometer 1 in

Product Description

The MITUTOYO 510-131 is a mechanical outside micrometer designed for precise external dimensional measurement in machining, fabrication, and quality-control applications. It covers a 1 inch measurement range with a graduation of 0.0005 inches and an accuracy of 0.000120 inches (3.00 micrometers). The measuring faces are solid carbide for long-term wear resistance. The spindle does not rotate during measurement, which reduces friction and helps protect the workpiece surface. This tool is suited for machinists, toolroom technicians, metrology professionals, and trade workers who need reliable, repeatable linear measurement in a bench or field setting.

The 510-131 is used wherever precise outside diameter, thickness, or length measurements are required on metal, plastic, or composite workpieces. It is appropriate for both production floor and quality-inspection use in light manufacturing, machine shops, and maintenance environments. The satin chrome finish reduces glare and improves readability under shop lighting. It ships with a fitted plastic case for protected storage and transport.

Key Features

• 1 inch measurement range with 0.0005 inch graduation for fine linear resolution
• Accuracy of 0.000120 inches (3.00 micrometers) for reliable precision measurement
• Solid carbide measuring faces resist wear during repeated use
• Non-rotating spindle design reduces friction and protects delicate workpiece surfaces
• Satin chrome finish minimizes glare and resists corrosion
• Includes a fitted plastic case for storage and transport

Compatibility

Designed as a standard mechanical outside micrometer suitable for general outside-dimension measurement tasks in machining, fabrication, and inspection applications.

Installation Notes

Outside micrometers require no installation but should be calibrated against a known standard or gauge block before use. Store the tool in its fitted case and avoid exposing it to shock, extreme temperatures, or moisture. Clean measuring faces with a lint-free cloth before and after use. Calibration and care should follow the manufacturer documentation and applicable metrology standards for the shop environment.
