What is a BSP screw?
Information
Point 1: There are three types of [BSP].
BSP screws (name: British Standard Pipe) - Applications: Mainly used in the UK and other former Commonwealth countries - Types: BSPT/BSPP/BSPF ⇒ Therefore, if only BSP is used, it is impossible to select the screw type.
BSPT=BSP.Tr. BSPP=BSP.Pl. BSPF=BSP.F.
Point 2) BSP standard is compatible with each ISO standard screw, so tools can be shared.
| BS Standard | ISO Standards |
|---|---|
| BSPT | R (male)/Rc (female) |
| BSPP | Rp/PS (female) |
| BSPF | G/PF (male and female) |
Tools such as taps and dies can be shared due to interchangeability as described above. Gauges cannot be shared due to different standards, and a gauge specifically designed for BSP is required.
