Dog-point data:
SHCHH & SHCHHS studs are available with a dog-point end to assist the attachment of mating nuts, which is especially useful in high speed production assembly using motorised nut drivers. Dog-points may be specified on all SCH, STCH and SHCH style studs as a special order, using the following part number structure:SHCHS 1032-8 DPWhere SHCHS = type, 1032 = thread, 8 = length and DP = dog-point.
