10PCS Thread Plug Gauge Set, 2B Precision Go/No-Go, High-Carbon Chromium Steel, H28 Hardness, Sandblasted, UNC/UNF, Size Marked, American Standard Inspection Tools with Storage Boxes

Product DescriptionThis 10-piece American-standard thread plug gauge set is engineered to provide precise and consistent thread inspection for industrial, electronic, and machinery applications. Each gauge is meticulously crafted from high-carbon chromium bearing steel using a sandblasting process for impressive durability, resisting deformation and wear over time. With a hardness of H28, these gauges maintain optimal accuracy even with repeated usage, making them ideal for robust quality control.The double-ended (Go/No-Go) design, with precision rated at 2B, ensures thorough inspection of both the maximum and minimum thread diameters, empowering technicians and engineers to detect tolerance deviations efficiently. Each piece is clearly size-engraved and marked with distinctive colors for rapid identification. Compact and lightweight, every gauge in the set comes with its own protective box for organized storage and easy portability. Covering an array of common UNC and UNF sizes, this set supports diverse industrial maintenance and inspection needs, providing reliable measurement assistant for consistent product quality.ApplicationIt is suitable for thread inspection in small-sized power tools, electronic products, electronic board circuits, and precision machinery manufacturing.SpecificationsColor: BlackStyle: ModernMaterial: High-carbon Chromium Bearing SteelProcess: SandblastingType: Thread Gauge(GO and NO GO)Scope of Application: American Standard Threaded BoreHardness: H28Accuracy: 2BNumber of Items: 10Gross Weight: 4kg/8.82 lbs Net Weight: 3.8kg/8.38 lbsPackage Size: 17*9.5*8.5cm/6.69*3.74*3.35inPackage Included1 x1/2 - 13UNC-2B1 x7/16 - 14UNC-2B1 x3/8 - 16UNC-2B1 x5/16 - 18UNC-2B1 x1/4 - 20UNC-2B1 x1/4 - 28UNF-2B1 x No10 - 32UNF-2B1 x No8 - 32UNC-2B1 x No6 - 32UNC-2B1 x No4 - 40UNC-2B10x Storage Boxes Notes1.
