Overview
This part of BS 919 specifies requirements for the following gauges intended for checking screw threads in the regular series, such as BS Whit., BS Fine, B.A., BSC and BS Conduit:
a) Screw gauges for general and reference use
b) Plain plug gauges and plain calliper gauges for the crests of threads
c) Setting plugs for adjustable screw ring and thread calliper gauges, GO and NOT GO.
This standard may be applied also to gauges for any screw threads of Whitworth form. It is intended for use with BS 84, which specifies the corresponding screw threads
This revision of BS 919 includes only the material relating to gauges for screw threads of Whitworth and BA forms.
BS 919-2:2007 contains:
- Normative references
- Terms and definitions and symbols
- Design
- Disposition of gauge tolerance zones
- Gauges for internal screw threads
- Gauges for external screw threads and their setting plugs
- Marking
This Part of BS 919 supersedes BS 919-2:1971, which is withdrawn.
