Metric Thread Plug Gauges - Go/No-Go 6H Tolerance M4-M12 Fine Thread Inspections
Precision 6H Tolerance Class: Compliant for accurate verification of metric fine threads (pitch: 0.25 mm- 3.5 mm) in automotive, aerospace, and machinery components.
Full Metric Range: Includes M4, M5, M6, M8, M10, M12 fine-thread gauges (e.g., M12×1.25) for external (screw plug) and internal (ring gauge) thread inspections.
Durable Tungsten Carbide Construction: Resists wear and corrosion, ensuring long-term accuracy even in high-volume production lines.
Double-Ended Go/No-Go Design: Combines "Go" (acceptance) and "No-Go" (rejection) ends on a single tool for rapid quality checks.
Mirror-Polished Surface: Smooth insertion reduces friction and prevents false readings caused by surface roughness.
The Metric Thread Plug Gauges set is engineered for precision thread inspection in manufacturing and quality control. Each gauge adheres to the 6H tolerance class, rigorously verifying thread pitch, major/minor diameters, and flank angles for critical components like engine bolts, hydraulic fittings, and CNC-machined parts.
Crafted from ultra-hard tungsten carbide, these gauges withstand repetitive use without deformation, making them ideal for inspecting stainless steel, aluminum, and alloy fasteners. The "Go" end ensures threads meet minimum acceptance criteria, while the "No-Go" end flags oversized or out-of-spec threads instantly.
Ergonomic Design: Knurled handles for secure grip.
Cost-Efficient Quality Control: Minimizes defective batches and reduces rework costs.
Thread Sizes:
Fine Threads: M4×0.5, M5×0.5, M6×0.75, M8×1.0, M10×1.25, M12×1.25
Coarse Threads: Optional (contact for customization)
Material: Tungsten Carbide with Anti-Corrosion Coating
