Thread Pitch Gauge 4PCS Metric Imperial US - Durable Screw Gauge Set

In this review the 4PCS Metric & Imperial & US Screw Gauge from ChgImposs is evaluated for shop and field use; it is best for machinists and fabricators who need a compact set to identify thread pitch and tool angles. The single biggest reason to buy is its combination of both 55 degree and 60 degree profile blades that cover Metric, Imperial and selected US sizes in one locked, stainless steel package, making quick checks on a lathe or during inspection much faster than switching individual gauges.

Key Features

• Dual angle blades: Contains 55 degree and 60 degree profiles so users can check both Whitworth and metric/US V-angles when setting up thread cutting tools on a lathe.
• Comprehensive size range: Includes a wide spread of Metric, Imperial and US sizes so most common workshop threads can be identified without extra gauges.
• Locking device: The lock up device keeps blades secure for safe handling and prevents accidental shifting while comparing thread profiles.
• Stainless steel construction: Blades are made of stainless steel with a wire-drawn finish that resists rust and maintains readable markings.
• Portable multi-set: Four screw gauge sets in the package provide spare or separate kits for different benches or toolboxes.

Who It's For

This gauge set is aimed at hobby machinists, workshop technicians and inspectors who need a compact, all-in-one tool to quickly determine thread pitch and tool angle. It is particularly useful when cutting threads on a metal lathe because the V-groove blades allow users to check the cutter angle against the gauge.

Those who require precision metrology for certification or high-tolerance production may want to look elsewhere or use this set as a quick reference alongside calibrated instruments, since some users report mixed results on fine readability and repeatable precision.

Pros & Cons

Pros

• Stainless steel blades with a locking device offer durable, rust-resistant construction and safe handling.
• Includes both 55 and 60 degree profiles to cover Whitworth and metric/US threads in one tool.
• Broad Metric, Imperial and US size lists allow identification of many common thread pitches without extra tools.

Cons

• The blades and markings are small, which can make readability difficult for some users in low light or without magnification.
• Accuracy reports are mixed among customers, so it is best used as a quick reference rather than a primary calibration instrument.

Specifications

Our Verdict

The ChgImposs 4PCS thread pitch gauge set is a practical, value-packed tool for machinists and technicians who need a portable way to check thread pitch and tool angle. It provides broad size coverage and durable stainless steel construction, making it a good workshop reference; however, anyone who needs lab-grade precision should pair it with calibrated measuring tools.

Frequently Asked Questions

Can this gauge check both Whitworth and metric threads?
Yes. The set includes 55 degree blades for Whitworth and 60 degree blades for metric and US profiles so both can be checked.

Is the set rust resistant?
The blades are stainless steel with a wire-drawn finish to resist rust and wear during normal workshop use.

Is this suitable for final inspection measurements?
It is best used as a quick reference for identifying pitch and setting up tools; for final inspection use calibrated metrology instruments.
