Appendix B

Gives general dimensions, including preferred lengths, for general purpose studs, and requirements for material, straightness and identification. Notes on recommended fitting practice also included. Limits and tolerances are specified for studs with UNF, UNC, B.S.F. and B.S.W. screw threads in diameters up to 1½ in and for studs with No. 2 and No. 4 B.A. screw threads.

Part One of this British Standard relates to screwed studs intended for general purposes and having threads with coarse or fine pitches in accordance with BS 1580, Unified screw threads (UNC or UNF); BS 84, Screw threads of Whitworth form (B.S.W. or B.S.F.); or threads in accordance with BS 93, B.A. screw threads.

The dimensional requirements of this standard apply both to ferrous and non-ferrous studs, but mechanical properties are given only in respect of steel studs.
