Starrett 50293 Surface Gage 2 Spindle Hardened Steel

Product Description

The STARRETT 50293 is a two-spindle surface gage used for precision layout, scribing, and inspection work in machine shops, fabrication environments, and industrial maintenance settings. The unit features a 9.5-inch spindle length and a hardened steel construction that resists wear under repeated shop-floor use. The base measures 3 inches long by 2.5625 inches wide, providing a stable footprint on surface plates, machine tables, and flat reference surfaces. This type of tool is typically handled by machinists, tool-and-die makers, and skilled maintenance technicians who require repeatable height transfer and part inspection capability.

The 50293 is suited for use on surface plates and flat machine surfaces in both production and job-shop environments. It supports scribing layout lines, checking runout, and transferring height measurements during part setup and inspection. The two-spindle configuration allows for flexible positioning of the scriber or indicator attachment. This surface gage is appropriate for light industrial and precision mechanical work where consistent contact and stable base positioning are required.

Key Features

• Two-spindle configuration for flexible scriber or indicator positioning
• 9.5-inch spindle length for extended reach on tall workpieces
• Hardened steel construction for wear resistance and long service life
• Base dimensions of 3 inches long by 2.5625 inches wide for stable surface contact
• Compact base profile suitable for standard surface plates and machine tables

Compatibility

Designed as an OEM-style surface gage for use on standard surface plates and flat reference surfaces in precision layout and inspection applications.

Installation Notes

Surface gages are set up by machinists or precision measurement technicians and require no permanent installation. Ensure the reference surface or surface plate is clean and free of burrs or debris before placing the base. Adjust spindle position and lock securely before scribing or transferring measurements. Do not use on non-flat or inclined surfaces where base stability cannot be confirmed.
