✨ This industrial thread gauge instantly sorts and verifies metric and standard inch bolts, nuts and screw threads, eliminating messy hardware sorting and mismatched fastener headaches for mechanics, builders and DIY users. 

Core Premium Industrial Features

🏗️ Heavy-Duty 6061 Aluminum Alloy Main Body

Thick solid 6061 aluminum frame delivers rigid warp-resistant stability, built to endure constant drops, workshop abrasion and years of daily heavy-duty checking cycles. The precision machined frame maintains perfect hole alignment without deformation even after thousands of measurements. Embedded SUS304 stainless steel threaded pegs match strict ANSI Class 2B Go & No-Go thread standards for ultra-accurate sizing readings every time.

📏 Dual System 34-Hole Full Size Coverage

Split layout clearly separates Metric and Imperial (Standard) sizing, covering coarse and fine thread pitches for all the most widely used fastener specs from M4 up to M16 and 6-32 up to 5/8 inch. Each hole is engineered to test both outer bolt diameter and internal nut threading in one quick fit test, cutting sorting time drastically. The compact 28-hole model includes the most popular frequently used sizes for portable, space-restricted tool bags.

🔍 Permanent Laser-Etched Size Markings

Sharp deep laser engraved labels never fade, wear or rub off with grease, oil and constant handling, unlike cheap printed plastic gauges. Every hole is clearly stamped with exact thread specs (such as M5×0.8, 1/4-20 Coarse) for instant visual recognition with zero guesswork.

🛡️ Anti-Slip & User-Friendly Build Details

Four built-in silicone anti-slip foot pads stop sliding across workbenches during checking. A long hanging slot lets you mount the gauge permanently on pegboards, tool walls or storage racks to keep it always accessible and organized. The smooth machined edges prevent scrapes on hands or hardware finishes during rapid sorting sessions.

⚡ Massively Boost Workshop Workflow

Swap slow trial-and-error nut-bolt matching for one-second fit checks. Sort jumbled mixed hardware piles neatly in minutes, eliminate costly assembly mistakes from mismatched threads, and speed up equipment repair, vehicle service, cabinet build and construction prep work significantly. Perfect for professional auto shops, fabrication garages, handymen and serious home DIY projects.

❤️Wide Application Fields

Essential measuring hardware for auto repair garages, metal fabrication shops, construction crews, furniture assembly, farm machinery maintenance, marine equipment upkeep, and residential DIY woodworking & appliance repair tasks.
