Value Collection 241106PR Precision Dowel Pin 1/8x1-1/4 in

Product Description

The VALUE COLLECTION 241106PR is a precision dowel pin designed for accurate alignment and locating applications in machined assemblies. Manufactured from alloy steel to Grade 8 material specification, it measures 1/8 inch in diameter and 1-1/4 inches in overall length. The pin holds a Rockwell hardness of 50-58 HRC, delivering the surface toughness required for press-fit and slip-fit bores in tooling, fixtures, and mechanical components. A diameter tolerance of 0.0002 inches ensures consistent, repeatable fitment across high-precision assemblies. End configuration is one beveled end and one rounded end per ASME B18.8.2, the governing standard for unhardened ground machine and precision dowel pins.

This dowel pin is suited for use in machine shops, manufacturing facilities, and maintenance environments where tight-tolerance component alignment is required. Typical applications include fixture plates, die sets, jig assemblies, and precision machinery requiring reliable part-to-part registration. The double-shear breaking strength of 3,200 pounds makes it appropriate for moderate load-bearing alignment duties in both horizontal and vertical orientations. Machinists, tool and die makers, and maintenance mechanics are the primary installers of this type of fastener.

Key Features

• Alloy steel construction with Grade 8 material specification for high hardness and shear resistance
• 50-58 HRC Rockwell hardness for wear-resistant press-fit and slip-fit service
• Diameter tolerance of 0.0002 inches for consistent high-precision fitment
• One beveled end and one rounded end per ASME B18.8.2 standard
• Double-shear breaking strength of 3,200 pounds
• Compliant with ASME B18.8.2 fastener standard

Compatibility

Designed as a standard ASME B18.8.2 precision dowel pin for use in any application requiring a 1/8-inch diameter, 1-1/4-inch length alloy steel locating pin with one beveled and one rounded end.

Installation Notes

Installation is performed by machinists or tool and die makers using appropriate press equipment or a mallet with a pin driver. Bore diameter and surface finish should be verified against the pin tolerance before installation to achieve the intended fit class. Always depressurize or de-energize the assembly before inserting or removing dowel pins in live equipment. Do not modify the pin ends or shorten the pin, as doing so alters the dimensional compliance with ASME B18.8.2.
