BSW / BSF / Whitworth (Whits) Thread Gauges

BSW Thread Gauge (British Standard Whitworth) is designed to inspect internal or external coarse thread profiles used in mechanical engineering, the petrochemical industry, and vintage vehicle maintenance components.

BSF Thread Gauges are often used to check British Standard Fine screw threads having a Whitworth form with a 55-degree thread angle. These thread gauges are essential in manufacturing and quality control to ensure proper fit with BSF bolts, engine and gearbox parts used in general mechanical engineering, the automotive industry, electrical engineering, and structural steelwork.

• Gauges manufactured to relevant BS 84, ANSI B1.2, and BS 919 Thread standards with Std/Customized Thread Pitch, Class, Tolerances, and Fittings.
• Manufactured in hardened, precision hand-lapped OHNS Steel material to provide superior accuracy, wear resistance, and optimum finish.
• Manufacturing Range: Dia. 1/16″ to Dia. 12″.
• Subzero treated at -80°C for Dimensional Stability.
• Calibrated at 20°C under Standards Room conditions.
• Gauges are delivered in plastic case, providing anti-corrosion effect and impact resistance with Calibration Certificate (NABL/NPL Accredited).
