Holo Krome 8058 3/8 x 3 Shoulder Screw

Description

This type of socketed screw, often called a "stripper bolt", is used for a wide range of punch and die operations. For swing arm or link, they provide concentricity between threads and shoulder to produce a uniformly accurate assembly. "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. Shoulder screws may be used as bearing pins. Diemakers and machine builders find practical economy in using standard Holo-Krome Shoulder Screws rather than making their own. Heads are made to a height admitting die clearance even in cramped designs. Over 73 stock sizes are available in diameters ranging from 1/4" to 3/4" and in shoulder lengths from 1" to 6". For swing arm or link, they provide perfect concentricity between threads and shoulder to produce a uniformly accurate assembly. A full line of metric and other non-standard sizes are available. Accurate sockets and precision Class 3 fit threads add up to holding power to withstand punishing shocks and stresses. The precision made possible by this process permits holding diameter tolerances to closer limits. Features: "Tru-Ground" Surfaces: Holo-Krome "Tru-Ground" process produces smooth, highly polished head and shoulder surfaces with unequalled concentricity between head and body. Uniform high quality is assured time and money saved.
