Spi MS220708047 Screw Pitch Gage Whitworth Thread

Product Description

The SPI MS220708047 is a screw pitch gage manufactured from steel and designed to measure Whitworth screw thread profiles. Screw pitch gages allow technicians and tradespeople to quickly identify thread pitch by matching blade profiles to threaded fasteners, fittings, or tapped holes. The MS220708047 is built for Whitworth thread forms, a standard commonly encountered in legacy plumbing fittings, British Standard Pipe connections, and older mechanical assemblies. The steel construction provides durability and resistance to wear during repeated use in shop or field environments.

This gage is suited for plumbing, pipefitting, and general mechanical trades where Whitworth or BSP thread identification is required. It is used during maintenance, repair, or fabrication work when confirming thread pitch before selecting replacement fasteners or fittings. The tool is equally useful in shop settings for incoming inspection and on job sites where older threaded components must be matched accurately.

Key Features

• Identifies Whitworth screw thread profiles for accurate fastener and fitting matching
• Steel construction for durability in repeated shop and field use
• Compact gage format for quick thread pitch verification
• Applicable to legacy plumbing fittings and British Standard Pipe thread systems

Compatibility

Designed for use with Whitworth screw thread forms, including applications involving older threaded fasteners, fittings, and components manufactured to British Standard specifications.

Installation Notes

This is a hand measuring tool and does not require installation. Store in a clean, dry location to prevent corrosion of the steel blades. When identifying thread pitch, fan through the blade set and match profiles carefully under adequate lighting to ensure an accurate reading. Handle blades with care to avoid nicking or bending the profiled edges.
