Spi 31-386-6 Stainless Steel Angle Gage 35 145 Degree

Product Description

The SPI 31-386-6 is a stainless steel angle gage used to measure and verify precise angular dimensions in fabrication, machining, and layout work. It features a 35-degree primary angle and a 145-degree complementary angle, giving technicians two reference surfaces in a single compact tool. The stainless steel construction resists corrosion and wear, making it suitable for shop floor use. At 0.01 pounds, the gage is lightweight and easy to handle for repetitive measurement tasks. Machinists, pipefitters, and fabricators rely on angle gages like this one to confirm setups and check part geometry before and after cutting operations.

This angle gage is appropriate for use in precision measurement applications across metalworking, pipe fabrication, and general manufacturing environments. It is well suited for confirming angle setups on milling machines, surface plates, and welding fixtures. The dual-angle format allows the user to reference either the acute or obtuse face depending on the measurement scenario, reducing the need for multiple individual gages.

Key Features

• 35-degree primary angle for standard angular reference
• 145-degree complementary angle on the opposing face
• Stainless steel construction for corrosion resistance and durability
• Lightweight at 0.01 pounds for easy single-hand use
• Compact form factor suitable for layout and inspection tasks

Compatibility

Designed as a general-purpose angle reference gage for use in precision measurement and layout applications across metalworking and fabrication trades.

Installation Notes

Angle gages are passive reference tools and do not require installation. Handle with clean, dry hands or lint-free gloves to prevent surface contamination that could affect measurement accuracy. Store away from impact and moisture when not in use to preserve the reference surfaces.
