Features: Double scale wedge tapers gauges with stainless steel construction enables precise millimeter/inch measurements for narrow gaps and welding inspections. Features a 1-15mm ranges, 0.1mm accuracy, and clear graduations for reliable hole, slot, and diameter measurements in tight space. Suitable for welders, quality inspectors, and mechanical engineers requiring multifunction dimension verification in confined workspaces. Perfect for automotive maintenance, metal fabrication, and precisions machining applications demanding double unit dimension analysis. Stainless steel calipers combines sharpness edges safety awareness with corrosion resistant durability for workshop and field measurement tasks.
