Spi 31-393-2 Stainless Steel Angle Gage 70 110 Degree

Product Description

The SPI 31-393-2 is a stainless steel angle gage used to measure and verify angular surfaces during layout, inspection, and machining operations. It features a 70-degree primary angle and a 110-degree complementary angle, giving the technician two reference surfaces in a single tool. The stainless steel construction resists corrosion and wear, making it suitable for shop-floor and bench use. At 0.02 pounds, it is a lightweight, hand-held precision tool suited for machinists, pipefitters, and fabricators who need repeatable angle references on the job.

This angle gage is used in metalworking, fabrication, and inspection applications where accurate angular reference is required. The 70-degree primary face is the working reference, while the 110-degree complementary face covers the supplementary angle of the same setup. It is appropriate for use in job shops, maintenance facilities, and manufacturing environments where layout and fit-up accuracy are critical to weld prep, part inspection, or machine setup.

Key Features

• 70-degree primary angle for direct angular reference during layout and inspection
• 110-degree complementary angle provides the supplementary measurement in the same tool
• Stainless steel construction resists rust and withstands shop-floor conditions
• Lightweight at 0.02 pounds for easy single-hand use
• Single-piece gage construction with no moving parts to wear or fall out of calibration

Compatibility

Designed as a general-purpose fixed angle gage for use in metalworking, fabrication, and precision inspection applications requiring 70-degree or 110-degree angular references.

Installation Notes

This tool is used by machinists, fabricators, and inspection personnel and requires no installation. Store the gage in a clean, dry location to protect the reference faces from nicks and corrosion. Handle with care to avoid dropping, which can alter the accuracy of the ground reference surfaces. Periodic verification against a certified angle block is recommended when the gage is used for critical dimensional inspection.
