Value Collection 34911 Pull Out Dowel Pin 1/2x3/4 in Alloy Steel

Product Description

The VALUE COLLECTION 34911 is a standard pull out dowel pin designed for precision alignment and locating applications in machined assemblies. Manufactured from Grade 8 alloy steel, this pin measures 1/2 inch in diameter and 0.7500 inches in overall length. It features one beveled end and one rounded end, with a hardness rating of 50-58 HRC for reliable resistance to wear and deformation under load. The tight diameter tolerance of 0.0002 inches ensures consistent, repeatable fit in close-tolerance bored holes. Machinists, tool and die technicians, and maintenance mechanics install these pins in fixtures, jigs, and production tooling where precise component registration is required.

This pin is suited for use in industrial machining, fixture building, and general metalworking applications where a removable, precision locating pin is needed. The pull out style allows for easier extraction from blind holes compared to standard press-fit dowel pins. The ASME B18.8.2 standard governs its dimensional and performance requirements, making it a recognized specification part for manufacturing and maintenance environments. Sold in packages of 10, it is practical for both initial builds and replacement stock.

Key Features

• Grade 8 alloy steel construction with 50-58 HRC hardness for wear resistance
• Diameter tolerance of 0.0002 inches for precision fit in close-tolerance bored holes
• One beveled end and one rounded end for guided insertion and pull out extraction
• Meets ASME B18.8.2 fastener standard for dimensional compliance
• Double shear breaking strength measurement for structural reliability
• Package quantity of 10 for stocking and replacement use

Compatibility

Designed as an OEM-style precision locating pin compatible with standard 1/2 inch diameter bored holes in machined fixtures, jigs, dies, and tooling assemblies conforming to ASME B18.8.2 dimensional requirements.

Installation Notes

Installation is typically performed by machinists or maintenance mechanics using standard press or hand-insertion tools appropriate for the fit class of the bored hole. Ensure the mating hole is clean, deburred, and dimensionally verified before installation. For pull out applications, a threaded puller or slide hammer may be required for safe extraction without damaging the hole or surrounding material. Always de-energize and lock out any equipment before servicing assemblies containing locating pins.
