Product Description
Precision Thread Plug Gauge BSW 1/4-20 Go and NoGo
Product Description
The BSW thread plug gauge is designed to verify the accuracy of internal BSW (British Standard Whitworth) screw threads. Developed by Joseph Whitworth, these threads feature a 55-degree thread angle. These precision gauges are essential for ensuring proper fit and interchangeability of parts, particularly in applications using the Whitworth thread standard.
Quick Details
- British Standard Whitworth (BSW) thread.
- Material: GCR15 bearing steel.
- Available in both right-hand (RH) and left-hand (LH) configurations.
- Wear-resistant and corrosion-resistant construction.
- Stable structure for easy operation.
- Supplied in a fitted protective case.

Applications
- Inspect internal BSW threads (nuts, threaded holes) for correct pitch diameter and form compliance.
- Verify BSW threads in legacy British-engineered equipment or military hardware.
- Check threaded components in vintage vehicles or machinery using Whitworth standards.
- Ensure proper sealing in pipe fittings with BSW threads (hydraulic systems).
- Assess wear/damage in existing BSW threads during overhaul or reassembly.
- Confirm compatibility between BSW-threaded parts from different manufacturers.
Precautions
- Use only for gauge inspection purposes - functional sharp parts may cause injury.
- Before use, inspect for rust, scratches, or burrs and clean with oil or cloth.
- Apply anti-rust lubricating oil during use and avoid impact.
- Store in a dry, temperature-stable environment after removing dust and chips.
- Perform regular maintenance checks.
