Bolt & Nut Size Gauge — Identify Thread Sizes Without the Guesswork

🔩 Bolt & Nut Size Gauge — Identify Thread Sizes Without the Guesswork

⚡ Find the Right Size Faster

Check common bolt and nut sizes directly on the gauge instead of repeatedly comparing loose hardware. Clearly marked threaded posts and matching holes make it easier to identify compatible sizes during repairs, maintenance and workshop projects.

📐 Metric & Standard Sizes on One Board

The layout combines metric and standard thread references in one organized tool, helping you handle a wider range of everyday hardware. Laser-etched markings keep each position easy to read while the separated layout makes size selection straightforward.

📏 Measure Length While You Check Threads

Built-in centimeter and inch scales along the edges let you check bolt length while identifying thread size, reducing the need to reach for a separate ruler during common workshop tasks.

🛠️ Durable Materials for Everyday Workshop Use

The gauge uses an Aluminum 6061 body with SUS304 threaded reference bolts, combining a rigid board with clearly organized measuring points. Anti-slip pads help stabilize the gauge on a work surface, while the hanging hole makes storage simple.

📦 Compact, Organized & Easy to Keep Nearby

At approximately 16.5" × 4", the slim board can be stored on a workbench or hung near your hardware area, keeping common thread references visible and ready whenever you need them.
