Value Collection 34887 Pull Out Dowel Pin 1/4x3/4 Alloy Steel Gr8

Product Description

The VALUE COLLECTION 34887 is a standard pull out dowel pin machined from alloy steel to Grade 8 specifications and certified to ASME B18.8.2. The pin measures 0.25 inches in diameter and 0.75 inches in overall length, with one beveled end and one rounded end for controlled installation and extraction. Hardness is rated at 50-58 HRC, supporting resistance to shear loads in precision alignment applications. Breaking strength is rated at 12,800 pounds in double shear. This pin is installed by machinists, tool and die technicians, and maintenance mechanics working on jigs, fixtures, dies, and production tooling.

Standard pull out dowel pins are used in applications where components must be repeatedly disassembled and realigned without loss of positional accuracy. The beveled lead end eases entry into the mating hole, while the opposite rounded end accepts a puller or punch for extraction. Typical installations include fixture plates, mold bases, machine housings, and press tooling in industrial and manufacturing environments. The 0.25-inch diameter and 0.75-inch length suit compact assemblies with tight stack-up requirements.

Key Features

• Conforms to ASME B18.8.2 fastener standard
• Packaged in quantities of 25 per unit

Compatibility

Designed as an OEM-style replacement or direct-fit component for standard 0.25-inch reamed dowel pin holes in fixtures, dies, mold bases, and precision machine assemblies conforming to ASME B18.8.2.

Installation Notes

Pull out dowel pins are installed by machinists or maintenance mechanics using a press or mallet into reamed holes sized to the pin diameter tolerance. Always de-energize and lock out machinery before servicing any assembly containing dowel pins. Use a proper dowel puller or slide hammer against the rounded end for extraction to avoid damage to the mating bore. Consult applicable facility standards and engineering drawings for hole depth and interference fit requirements.
