50PCS Thread Checker Kit – SAE & Metric Bolt Thread Checker

Nut and bolt thread checker with 50 pcs male and female gauges - perfect for everyday mechanical work or home projects. ---DURABLE AND ACCURATE: The Thread Checker Red and Blue is made of aluminum alloy for accurate threading. In addition, this thread gauge SAE and metric is available in 27-inch sizes and 23 metric sizes, each with male and female sides for bolts and nuts, which will be great for you, especially if you have to deal with these two different standards in your fastener projects. ---REMOVABLE FUNCTION: All thread gauges are individually encapsulated in premium EVA foam. The best part about the Screw Size and Bolt Size Thread Checker is that you can easily remove any part you need to quickly identify nut and bolt sizes. No more gripping large, bulky and non-removable cable thread checkers or plate/metal on plate thread checkers to rotate the entire body for inspection, especially if you need to size equipment or some very tricky and narrow areas. Greatly improves work efficiency. --- Inch and metric are color-coded in two ways: to better distinguish between metric and inch sizes, we make inch and metric parts in different colors (blue for SAE, red for metric). 27 Standards Shown (Blue): 2-56 UNC, 4-40 UNC, 6-32 UNC, 8-32 UNC, 10-24 UNC, 10-32UNF, 12-24 UNC, 1/4-20 UNC, 1/4-28UNF, 5/16-18 UNC, 5/16-24 UNF, 3/8-16 UNC, 3/8-24 UNF, 7/16-14 UNC, 7/16-20 UNF, 1/2-13 UNC, 1/2-20 UNF, 9/16-12 UNC, 9/16-18 UNF, 5/8-11 UNC, 5/8-18 UNF, 3/4-10 UNC, 3/4-16 UNF, 7/8-9 UNC, 7/8-14 UNF, 1-8 UNC, 1-12 UNF. 23 Metrics Shown (Red): M2X0.4 Coarse, M2.5X0.45 Coarse, M3x0.5 Coarse, M4x0.7 Coarse, M5x0.8 Coarse, M6x1.0 Coarse, M7x1.0 Coarse, M8x1.0 Fine, M8x1.25 Coarse, M10x1.0 Fine, M10x1.25 Fine, M10x1.5 Coarse, M12x1.25 Fine, M12x1.5 Fine, M12x1.75 Coarse, M14x1.5 Fine, M14x2.0 Coarse, M16x1.5 Fine, M16x2.0 Coarse, M18x1.5 Fine, M18x2.5 Coarse, M20x1.5 Fine, M20x2.5 Coarse. ---Multiple Ways to Read and Match Sizes You can quickly identify thread sizes in three ways: laser-etched markings on thread checkers, printed size chart stickers, and screen-printed labels on foam trays.
