80Pcs Thread Checker, Aluminium Nut and Bolt Gauge Set (70) 41 Metric & 39 Imperial Sizes, Aviation Aluminium, Triple Reading System, Covers Rare Custom Foam Storage Case

70-Piece Master Set: Covers 37 Imperial (2-56 to 1-12) and 33 Metric (M2x0.4 to M24x3.0) sizes. Features both male and female threads, offering complete compatibility for most common nuts, bolts, and washers. Precision Alloy & Rust-Proof: Machined from high-quality alloy for reliable accuracy. The colour-coded anodised finish (Red for Metric, Blue for Imperial) resists rust and keeps markings clearly legible in oily or humid workshops. Detachable for Tight Spaces: Unlike bulky fixed boards or wire-bound gauges, these individual checkers can be carried straight to the job. Easily identify threads in narrow gaps, engine bays, or recessed holes. Upgraded Sturdy Storage: Housed in a heavy-duty case with secure dual-locking latches. A custom-cut, high-density foam insert with screen-printed size labels keeps all pieces neatly organised and protected from accidental drops. Time-Saving Mechanic Gift: Instantly identify mixed fasteners by screwing them onto the matching gauge. A highly practical addition to any toolbox, making it a perfect gift for mechanics and DIY enthusiasts.
