Instant Nut and Bolt Thread Identifier
Quickly verify thread pitches and diameters. Features 26 precision-machined gauges neatly compiled on a flexible high-strength steel loop for quick and seamless hardware sorting.
Vibrant Metric & Imperial Dual Coding
The layout is cleanly divided by bright mechanical finishes. Deep blue anodized components indicate imperial inch sizes, whereas rich red parts house standard metric measurements. High-contrast laser-etched markings display sizes prominently on both sides.
Precision Anodized Aluminum Gauges
Each dual-sided test cylinder is CNC-formed out of lightweight, rust-resistant anodized aluminum. Fitted with accurately machined external threads (male studs) on one side and matching internal threads (female ports) on the other to facilitate instant test fits.
Engineered for Various Fields
Ideal for mechanics, carpenters, maintenance technicians, and DIY garage hobbyists. Keep it within reach to secure fasteners on various hardware equipment.
Car Maintenance
Identify automotive bolts quickly when performing under-the-hood or chassis repairs.
Bicycle Repair
Sort through fine-threaded frame components, brake hardware, and stem bolts.
Machinery Sorting
Verify machine thread pitches before mounting heavy apparatus or mounting structures.
Home Appliance Fixes
Quickly determine standard dimensions of fixing hardware on domestic cooling systems and brackets.

Frequently Asked Questions
⚙️ How do I test bolts and nuts using this gauge loop?
To verify a bolt, thread it into the female-threaded sleeve end of the corresponding gauge size. To verify a nut, screw it onto the male-threaded post until it seats flush. A smooth fit verifies the size.
⚙️ Are the individual sizes removable from the main wire loop?
All 26 gauges are held on a continuous stainless steel cable assembly to prevent loss. This keeps the set organized and easy to carry inside toolboxes or hang on pegboards.
⚙️ How do I tell the metric sizes apart from the imperial sizes?
The tool uses a color-coded layout. Metric sizes are anodized in vibrant red, while imperial sizes are anodized in deep blue. Every size identifier is laser-engraved with white indicators.
