Spi 31-385-8 Stainless Steel Angle Gage 30 150 Degree

Product Description

The SPI 31-385-8 is a stainless steel angle gage used to set, check, and transfer precise angular measurements during layout and machining operations. It features a 30-degree primary angle and a 150-degree complementary angle, giving the technician two reference surfaces in a single compact tool. Constructed from stainless steel, the gage resists corrosion and maintains dimensional stability in shop environments. It is a hand-held reference tool typically used by machinists, tool and die makers, and precision fabricators who need repeatable angle verification without a protractor or angle block setup.

The 31-385-8 is suited for metalworking and fabrication shops where fixed-angle references are required for part inspection, fixture setup, or layout work. The dual-angle design allows the user to reference either the 30-degree or 150-degree face depending on the workpiece geometry. Its compact, lightweight form makes it practical for bench work and in-process checks on milling machines, surface plates, and layout tables.

Key Features

• 30-degree primary angle for direct layout and inspection reference
• 150-degree complementary angle provides a second reference surface on the same tool
• Stainless steel construction resists corrosion and wear in production shop conditions
• Lightweight at 0.01 pounds for easy one-handed use during layout operations
• Single-piece design with no moving parts reduces calibration concerns

Compatibility

Designed as a general-purpose fixed-angle gage for use in metalworking, machining, and precision fabrication applications where a 30-degree or 150-degree angle reference is required.

Installation Notes

No installation is required for this hand tool. Before use, inspect the reference faces for burrs, nicks, or debris that could affect measurement accuracy. Clean the contact surfaces and the workpiece with a lint-free cloth before taking a reference. Store the gage in a protective case or dedicated tool drawer to prevent surface damage.
