Applications:
• Continuous grain flow resists chipping of ends. Precision heat treated for greater strength and surface hardness.
• Chamfered end provides easier insertion in hole. Surface finish to 4 microinch maximum.
• Widely used as plug gages in various production operations and as guide pins, stops, wrist pins, hinges and shafts. Also used as position locators on indexing machines,
as feeler gages in assembly work, as valves and valve plungers on hydraulic equipment, as fasteners for laminated sections and machine parts, and as roller bearings in casters and truck wheels.
Hardened dowel pin:
• Made from high grade stainless steel with material certificate.
• Heat treated for wear-resistant surface (HRC 60 +/-2).
• Controlled radius - resists mushrooming during assembly.
• True-round diameter - precision ground on centerless grinders to
roundness .00008 inch and 4 RMS microinch surface finish.
• From end to end, diameter is truly held to a tolerance of +/- .00006.
• Point chamfer accurately held - permits easier insertion and starting without marring exteriors polished surface
•Various materials, diameters, lengths, end configurations, heat treatment, and finishes are available. Feel free to contact us .
• Inch Series: ASME/ANSI B18.8.2
