This type of socketed screw, often called a “stripper bolt”, is used for a wide range of punch and die operations.
HOLO-KROME’s shoulder screws are commonly used as fulcrums or pivots in machine designs that involve links, levers or other oscillating parts.
Diemakers and machine builders find practical economy in using standard HOLO-KROME Shoulder Screws rather than making their own. Uniform high quality is assured – time and money saved. Over 73 stock sizes are available in diameters ranging from ¼” to ¾” and in shoulder lengths from 1” to 6”. A full line of metric and other non-standard sizes are available.
Shoulder screws may be used as bearing pins. For swing arm or link, they provide perfect concentricity between threads and shoulder to produce a uniformly accurate assembly.
SIGNIFICANT FEATURES:
- • “Tru-Ground” Surfaces: HOLO-KROME “Tru-Ground” process produces smooth, highly polished head and shoulder surfaces with unequalled concentricity between head and body. The precision made possible by this process permits holding diameter tolerances to closer limits. Heads are made to a height admitting die clearance even in cramped designs. “Tru-Ground” surfaces impose maximum resistance through fiction.
- • Made of Heat-Treated Alloy Steel: Use of alloy steel heat-treated to exactly uniform hardness, gives these screws the correct balance of strength and toughness. Accurate sockets and precision Class 3 fit threads add up to holding power to withstand punishing shocks and stresses.
