【Aluminum Alloy Board & Stainless Steel Studs】The thread gauge tool is made of solid aluminum alloy and finished in bright anodized orange. The threaded holes pass right through the main aluminum plate, and the threaded studs are all made of stainless steel, without burrs and very smooth to the touch. Nuts, washers, bolts and machine screws are easily threaded for accurate measurement, so this standard and metric thread checker makes it easy to categorize your items.
【Metric & Standard, Centimeters & Inches】The bolt size and thread gauge tool quickly identifies 28 different sizes, allowing you to organize scattered piles of screws and bolts. Metric thread sizes: from M4x0.7 to M14x2.0, Standard thread sizes: from 6–32 fine to 1/2–20 fine. There are scales on both sides of the nut and bolt thread checker tool from 0-15 cm and 0-6 inches respectively, making it easy to quickly measure the screw length.
【Easy to Store and Carry】The bolt gauge's multiple hanging notches give you the option to mount it on a wall, cabinet door or near a workbench for quick and easy access. There are four rubber supports on the back to keep the board off the surface. The overall dimensions of the aluminum plate are approximately 15.6x4 inches and the thickness is 0.2 inches. The bolt measuring tool is compact enough to be held in one hand, and its sturdy design allows you to easily carry it to different work sites.
【High-Precision Machining & Clear Marking】The thread checker tool is machined with high precision to ensure every internal and external thread meets Go & No Go Class 2B ANSI standard specifications to help you take the guesswork out of screw and bolt identification. We use professional laser etching technology to create precise markings on our thread checker boards that will never fade or scratch and remain clear and easy to read even after years of use.
