Value Collection 615-6326 Screw Pitch Gage 1-12 Tpi 16 Leaf

Product Description

The VALUE COLLECTION 615-6326 is a 16-leaf screw pitch gage used to identify and verify thread pitch on fasteners and threaded components. Each leaf is stamped with a specific threads-per-inch (TPI) value, allowing a technician to fan through the set and match the leaf to the workpiece for a quick, reliable reading. The gage covers a range of 1 to 12 TPI and is built around a 29-degree thread angle, making it suited for identifying unified and standard coarse-pitch thread forms. Machinists, maintenance technicians, and trade professionals working with threaded fittings, pipe, and hardware use this type of gage during inspection, repair, and fabrication work.

This screw pitch gage is a standard hand tool used in machine shops, maintenance facilities, and field service applications wherever threaded fastener identification is required. The 1 to 12 TPI range covers coarser thread pitches common in larger fasteners, pipe threads, and heavy equipment hardware. At 0.0225 pounds, the tool is compact and lightweight enough to carry in a technician's pouch or toolbox. It is appropriate for use by HVAC technicians, pipefitters, millwrights, and general maintenance personnel who routinely encounter a wide variety of threaded components.

Key Features

• 16 individual leaves, each stamped with a distinct TPI value for fast pitch identification
• Covers 1 to 12 TPI range for coarse and large-pitch thread verification
• 29-degree thread angle suits standard unified thread form profiles
• Compact form factor at 0.0225 pounds for easy portability
• Fan-style leaf design allows single-hand operation during fastener matching

Compatibility

Designed for general-purpose thread pitch identification on standard fasteners, fittings, and threaded components with a 29-degree thread angle and pitches falling within the 1 to 12 TPI range.

Installation Notes

No installation is required for this hand measurement tool. To use, fan the leaves and place each against the threaded workpiece until the leaf seats flush with no gaps along the thread flanks. Always clean threads of debris before measuring to ensure an accurate match. No special tools or certifications are required for operation.
