Spi 35-860-6 Plug Thread Gage Handle M33 to M39

Product Description

The SPI 35-860-6 is an aluminum plug thread gage handle designed for use with plug thread gages covering thread sizes M33 to M39. The handle measures 5-1/2 inches and provides the grip and leverage needed to properly seat and rotate a plug gage through a threaded bore. Built to ANSI standards and supplied with a traceability certification, this handle is intended for use in precision inspection environments by machinists, quality control technicians, and toolroom professionals who need reliable, repeatable thread verification on medium-to-large metric fastener applications.

This handle is used in manufacturing, production, and inspection settings where metric threaded bores in the M33 to M39 range require GO/NO-GO gage verification. It is suited for both shop-floor inspection stations and toolroom setups. The aluminum construction keeps the handle lightweight while providing the rigidity required for consistent gage handling. A traceability certification is included, making it suitable for quality systems that require documented calibration chain records.

Key Features

• Fits plug thread gages in the M33 to M39 thread size range
• 5-1/2 inch handle size for controlled grip and rotation during inspection
• Aluminum construction — lightweight and corrosion resistant
• Manufactured to ANSI standards for dimensional conformance
• Traceability certification included for quality management system compliance

Compatibility

Designed for use with plug thread gages covering M33 to M39 plug thread sizes. Confirm gage shank diameter is appropriate for this handle size before use.

Installation Notes

Installation of this handle onto a plug gage should be performed by a qualified inspector or toolroom technician. Ensure the gage shank is fully seated and secured in the handle before use. Do not force a gage through a threaded bore — apply steady, even hand pressure to avoid damaging the gage or the part being inspected. Store gages and handles in a controlled environment to maintain calibration integrity.
