Industrial 304 Stainless Steel Durability: Crafted from rust-proof 304 stainless steel, this gauge card withstands corrosion, impacts, and daily workshop abuse. Its military-grade construction ensures lifelong precision even in harsh environments.
Instant 3-in-1 Thread Measurement: Accurately measure bolt/screw diameter (SAE/Metric), pitch (Imperial/Metric), and length in seconds—no digital tools needed. Laser-etched slots eliminate guesswork for perfect fastener matching.
High-Contrast Laser Etching for Low-Light Readability: Deeply engraved markings resist fading and grease stains. Read sizes effortlessly in dim garages or bright job sites—saves 15+ minutes per repair vs calipers.
Universal Compatibility: #0 to M18 & 1/4"-3/4": Covers all common standards: machine screws (#0-14), SAE bolts (1/4"-3/4"), and metric threads (M3-M18). Essential for automotive, HVAC, machinery, and precision engineering.
Credit Card Portability for On-The-Go Pros: Slim as a wallet (3.9"x2", ), it slides into tool belts, pockets, or caliper cases. Always ready for emergency field repairs or shop use.
