Holo Krome 8058 3/8 x 3 Shoulder Screw

Description

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