Description

BS 1580-1 specifies limits of sizes, and tolerances, for single-start, clearance-fit unified screw threads, in inch units, with nominal diameters in and above, having the ISO basic profile as specified in BS ISO 68-2:1998.

BS 1580-1specifies the following unified thread series as follows:

a) standard variable pitch series:

  • a coarse thread series (UNC) from 1/4 in to 4 in nominal diameter
  • a fine thread series (UNF) from 1/4 in to 1 1/2 in nominal diameter
  • an extra fine thread series (UNEF) from 1/4 in to 1 1/16 in nominal diameter

b) standard constant pitch series:

  • a 4-threads per inch series (4 UN) from 2 5/8 in to 6 in nominal diameter
  • a 6-threads per inch series (6 UN) from 1 7/16 in to 6 in nominal diameter
  • an 8-threads per inch series (8 UN) from 1 1/16 in to 6 in nominal diameter
  • a 12-threads per inch series (12 UN) from 5/8 in to 6 in nominal diameter
  • a 16-threads per inch series (16 UN) from 7/16 in to 6 in nominal diameter
  • a 20-threads per inch series (20 UN) from 5/16 in to 3 in nominal diameter
  • a 28-threads per inch series (28 UN) from 5/16 in to 1 1/2 in nominal diameter
  • a 32-threads per inch series (32 UN) from 7/16 in to 1 in nominal diameter

c) a special thread series (UNS) with diameter/pitch combinations other than those specified for the standard series.

BS 1580-1  is intended for use with BS 919-1 and BS 919-4 which specify the corresponding screw gauges.
