Spi 13-674-7 Surface Gage 2 Spindle 4.875in

Product Description

The SPI 13-674-7 is a two-spindle surface gage used for precision layout, inspection, and scribing work on machine surfaces and surface plates. It features a 2-1/4 inch long by 1-5/8 inch wide base and an overall height of 7/8 inches, with two spindles each measuring 4-7/8 inches in length. The compact base provides stable contact on flat reference surfaces, and the dual-spindle configuration allows simultaneous setup or independent height adjustment. Machinists, tool-and-die workers, and quality-control technicians use this type of gage when transferring measurements or establishing reference lines on workpieces.

This surface gage is suited for use in machine shops, toolrooms, and inspection departments. It is appropriate for layout work on surface plates, checking parallelism, or scribing lines at a set height. The low-profile base and dual spindle design make it practical for workpieces that require two simultaneous contact points or scribing at two heights without resetting. It is typically used alongside a surface plate and height gage or dial indicator setup.

Key Features

• Two spindles for simultaneous or independent height adjustment
• Spindle length of 4-7/8 inches per spindle
• Compact base measuring 2-1/4 inches long by 1-5/8 inches wide
• Low overall height of 7/8 inches for stable surface contact
• Suited for layout scribing, inspection, and reference-line transfer tasks

Compatibility

Designed as a general-purpose surface gage for use with standard surface plates and inspection setups in machining and toolroom environments.

Installation Notes

Surface gages are set up and used by machinists and quality-control technicians on a clean, flat reference surface such as a granite or cast-iron surface plate. Ensure the reference surface is free of burrs, chips, and debris before placing the gage. Spindle positions should be adjusted and locked according to the measurement or scribing task before contacting the workpiece. Handle scribing points and spindle tips carefully to avoid personal injury.
