About This

• 【Optimised Spacing】 We’ve upgraded this 10.63x7.88-inch thread checker to keep it portable while fine-tuning the spacing between each bolt. This prevents overcrowding or collisions, ensuring that even larger nuts can spin freely on the bolts.
• 【Time Saver】 Our bolt measuring tool quickly identifies 44 different sizes, covering 22 metric sizes (from M2 x 0.4 to M20 x 2.5) and 22 standard sizes (from 2-56 Coarse to 3/4-16 Fine). It even includes those often-ignored smaller sizes, so you won’t need to make multiple trips to the hardware store just for one bolt.
• 【No Sticking】 We test every thread checker standard and metric to ensure nuts won’t get stuck halfway, giving you smooth, frustration-free operation every time.
• 【Built to Last】 Crafted from 0.24-inch thick aluminum alloy and precision-machined with CNC, this nut and bolt thread checker is anodized for corrosion resistance. It’s lightweight yet tough enough to handle heavy-duty use.
• 【Laser Etching】 The thread gauge sae and metric features laser-etched markings that are accurate, easy to read, and built to last. Plus, it comes with a handy built-in dual-scale ruler (20 cm/8 inches) to make measuring bolt lengths a breeze.
• 【Portable】 With pre-drilled mounting holes, you can hang this bolt size finder on the wall to save space. The rubber pads on the back keep it stable and slip-free while you work.
