Shoulder Bolts

Shoulder Bolts are hex socket drive head bolt fasteners with long non threaded shank/shoulder between the head and the threaded end. The shoulder diameter is larger than the thread diameter. The purpose of this non threaded shoulder is to allow rotation of the attached parts of a mechanical assembly, engines and pulleys, etc. stripper bolts, hex socker shoulder bolts are other alias of hex head bolts. Stripper bolts comes with round plain, knurled, low profile or even hex head design. Shoulder bolt dimensions are defined in both metric and imperials sizes with unified national coarse pitch (UNC), fine pitch (UNF), fixed pitch (UN) and iso metric thread profile. These can be produced across all material categories and various astm specifications including f568 grade 8.8, 10.9 and 12.9, which are most common
