Value Collection SF043030 Dowel Pin 1/4x7/8 in Alloy Steel Gr8

Product Description

The VALUE COLLECTION SF043030 is a precision dowel pin used to align, locate, and retain mating components in assemblies requiring tight positional tolerances. Machined from Grade 8 alloy steel with a hardness of 50-58 HRC, this pin delivers the strength and wear resistance demanded by industrial and mechanical applications. It measures 1/4 inch in diameter and 7/8 inch in overall length. One end is beveled and the other is rounded, allowing controlled press-fit or slip-fit installation into drilled and reamed holes. Breaking strength is rated at 12,800 units in double shear. Manufactured to ASME B18.8.2 standards. Machinists, toolmakers, and assembly technicians are the primary installers.

This dowel pin suits applications in jigs, fixtures, dies, molds, and precision machine assemblies where accurate part alignment is critical. The 1/4 inch diameter and 7/8 inch length make it appropriate for light-to-medium duty fastening and locating tasks in both production and maintenance environments. Its Grade 8 alloy steel construction handles applications where standard carbon steel pins would wear or deform under load. Sold individually per package with a minimum order quantity of 100 units.

Key Features

• Grade 8 alloy steel construction with 50-58 HRC hardness for high wear resistance
• One beveled end and one rounded end for guided press-fit or slip-fit installation
• Breaking strength of 12,800 in double shear for reliable load-bearing performance
• Diameter tolerance of 0.0002 inches for precision fit in reamed holes
• Manufactured to ASME B18.8.2 fastener standard
• Compact 1/4 x 7/8 inch size suits space-constrained assemblies

Compatibility

Designed as an OEM-style precision locating pin for use in fixtures, dies, molds, and mechanical assemblies requiring ASME B18.8.2 compliant dowel pins with a 1/4 inch diameter.

Installation Notes

Precision dowel pins are installed by machinists and toolmakers using a drill press or arbor press with properly reamed holes sized to the specified diameter tolerance. Ensure the receiving holes are deburred and clean before pressing the pin. A light film of machine oil on the pin body eases insertion and reduces the risk of galling the bore. Never strike the pin directly with a hammer without a proper driver to avoid deforming the end geometry or misaligning the assembly.
