  • Most of these BSW – Whitworth hex head bolts are, ‘rarer than chickens teeth,’ and cannot be replenished, hence, the price tags.

Bolt vs Screw

A screw screws into something, a bolt joins several parts together, applying compression both sides of materials joined. A screw is fully threaded from underneath the head and a bolt is partially threaded (has a part-plain shank)

 

British Standard Whitworth (BSW) is a thread form developed by Sir Joseph Whitworth in 1841. The thread form has rounded roots and crests, a thread angle of 55 degrees; the thread form is specified in BS 84: 1956
