Precision Nut and Bolt Thread Checker :The Namoka Thread Checker undergoes ultra-precise machining to ensure that every bolt and thread meets the pass/fail criteria of ANSI Class 2B gauge standards, ensuring the dimensional accuracy of both internal and external threads.Easily and precisely measure hardware dimensions—no more guesswork or mismatches.
Wide Compatibility with 31 Thread Sizes: Accurately identifies 15 metric threads (M2 x 0.4 to M12 x 1.75) and 16 standard threads (2-56 UNC to 1/2-20 UNF). It includes smaller sizes (M2 x 0.4 min.), making it ideal for sizing household bolts and nuts, and is an essential tool for DIY enthusiasts, home repair technicians, mechanical maintenance workers, and automotive repair professionals.
Premium Durable Materials & Craftsmanship: Each stud is made of 304 stainless steel, while the main body is crafted from aluminum alloy. The scale markings are laser-engraved, and the surface undergoes anodizing treatment. All these features ensure our threaded stud inspection plate is rust-resistant, corrosion-resistant, scratch-proof, sturdy, aesthetically refined, and built to last.
The Refined Design Enhances Usability: With extended stud spacing (0.55" to 0.71"), it accommodates nuts/studs of more varied shapes, preventing adjacent fastener interference during identification. The 0.51" exposed stud height ensures deep engagement with nuts for precise matching.
Convenient Installation & Practical Design: Features two hanging holes plus four corner holes for flexible mounting (pegboard/wall) or stable flat-surface placement. The dual-sided rulers (15 cm / 6 in) enable quick bolt length measurement.
