Value Collection -34895-1 Dowel Pin 5/16x1-1/4 Alloy Steel Gr8

Product Description

The VALUE COLLECTION -34895-1 is a standard pull out dowel pin machined from alloy steel to Material Grade 8 specifications. Measuring 5/16 inch in diameter and 1-1/4 inches in overall length, it delivers a diameter tolerance of 0.0002 inches for precise, repeatable alignment in mechanical assemblies. The pin features one beveled end and one rounded end, conforming to ASME B18.8.2, and achieves a Rockwell hardness of 50-58 HRC for resistance to deformation under load. Machinists, tool-and-die technicians, and maintenance professionals install this pin in fixtures, jigs, and machine components where accurate part positioning and positive pull-out capability are required.

This dowel pin is suited for use in industrial machinery, tooling fixtures, press-fit alignment applications, and precision mechanical assemblies across manufacturing and maintenance environments. The pull-out design allows removal without damage to the mating component, making it appropriate for assemblies that require periodic disassembly and re-registration. It is sold in a package quantity of 25 with a minimum order quantity of 1.

Key Features

• ASME B18.8.2 conformance ensures dimensional consistency and interchangeability
• 50-58 HRC hardness provides high shear strength and wear resistance
• 0.0002-inch diameter tolerance for tight, repeatable alignment fits
• One beveled end and one rounded end for controlled press-fit installation and pull-out removal
• Double shear breaking strength measurement standard
• Alloy steel construction, Grade 8, rated for demanding load applications

Compatibility

Designed as a standard ASME B18.8.2 pull out dowel pin for use in precision tooling, fixtures, jigs, and mechanical assemblies requiring a 5/16-inch nominal diameter alignment pin.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using an arbor press or appropriate driving tool sized for the pin diameter. Ensure the receiving hole is reamed to the correct tolerance before installation to avoid galling or binding. For pull-out removal, use a pin extractor or slide hammer rated for the pin size. Do not drive or remove the pin with impact tools that may deform the precision-ground diameter.
