Gazzar Posted December 12, 2017 Share Posted December 12, 2017 A friend has very kindly offered to draw up the blueprints for series light weight rear half shafts, so I can get some made up in heavy duty 4340 steel. Can anyone confirm that the thread of the axle retainer bolt is 1/4 BSF? It's the one thing we forgot to measure. Thanks, G. Quote Link to comment Share on other sites More sharing options...
steve b Posted December 12, 2017 Share Posted December 12, 2017 Are you referring to the spin on halfshaft retainer plate with holes to align with the drive member ? 1/4" UNF I think , although I don't have one here to check .. cheers Steve b Quote Link to comment Share on other sites More sharing options...
Gazzar Posted December 12, 2017 Author Share Posted December 12, 2017 Precisely! Absent a thread measuring set, how would I determine the thread? Quote Link to comment Share on other sites More sharing options...
steve b Posted December 12, 2017 Share Posted December 12, 2017 1/4" BSF 26 threads per inch and 1/4" UNF 28 TPI . I assume the drive member bolts are 9/16" AF which is UNF which would suggest UNF for other axle threads ? cheers Steve b Quote Link to comment Share on other sites More sharing options...
Gazzar Posted January 6, 2018 Author Share Posted January 6, 2018 Finally found a bolt with the same thread. Half inch has 14 threads, so 1/4 unf it is. Thank you. G. Quote Link to comment Share on other sites More sharing options...
