EXCLUSIVE 58-Piece
Thread Pitch Gauge (Metric/Imperial/US): This set goes beyond competitors with a dedicated 58-blade pitch gauge for measuring threads per inch and millimeter. Includes 24 Metric blades ( 0.25, 0.3, 0.35, 0.4, 0.45, 0.5, 0.6, 0.7, 0.75, 0.8, 0.9, 1.0, 1.25, 1.5, 1.75, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, 6.0 mm), 28 Imperia-Sized blades (4G, 4.5G, 5G, 6G, 7G, 8G, 9G, 10G, 11G, 12G, 13G, 14G, 16G, 18G, 19G, 20G, 22G, 24G, 25G, 26G, 28G, 30G, 32G, 36G, 40G, 48G, 60G, 62G), and 6 US blades (8, 10, 11, 14, 19, 28). Perfect for identifying unknown screw pitches, restoring threaded holes, and precision machining tasksa must-have for machinists and toolmakers.
Detachable & Flexible for Tight Spaces: Unlike bulky chain-style or fixed board checkers, our individual gauges pop out of the high-density foam case. This allows you to easily reach into confined spaceslike behind an engine block or inside machineryto test a bolt or nut directly. Simply thread the fastener onto the correct gauge for an instant, accurate size reading without disassembling half your project.
Triple-Marking System for Error-Free Reading: Speed is nothing without accuracy. We've made size identification effortless with three clear methods: 1) Laser-etched permanently on each durable aluminum gauge, 2) Printed clearly on the included reference chart, and 3) Screen-printed on the foam slot itself. The color-coded design (Blue=SAE, Red=Metric) eliminates squinting in dimly lit workshops, making this bolt size finder tool a joy to use.
Professional-Grade Construction & Complete Workshop Organizer: The 52 thread checkers are crafted from high-strength aluminum with a wear-resistant oxide coating, while the 58-blade pitch gauge is made from durable stainless steel. When you're done sorting or repairing, everything nests securely in the custom foam storage case. No more lost tools or jumbled drawersjust a perfectly organized workspace and the right tool for the job, every time. Ideal for professional mechanics, machinists, and serious DIYers.
