Value Collection 251214PR Oversized Dowel Pin 5/16x1 in Alloy Steel

Product Description

The VALUE COLLECTION 251214PR is a military specification oversized dowel pin manufactured from alloy steel for use in precision alignment and fastening applications. This pin measures 5/16 inch in diameter and 1 inch in overall length, with a diameter tolerance of 0.0010 inch to ensure accurate fit in close-tolerance bores. It features one beveled end and one rounded end. Hardness is rated at 50-58 HRC, and the pin carries a double-shear breaking strength of 20,000 pounds. It meets ASME B18.8.2 fastener standards and is suited for demanding mechanical assembly work performed by machinists, maintenance technicians, and industrial tradespeople.

This dowel pin is intended for use in precision alignment of mating components such as fixtures, dies, tooling plates, and machinery housings where oversized fit is required to compensate for bore wear or to achieve an interference fit. The military specification designation indicates it meets tighter dimensional and hardness controls than standard commercial dowel pins. It is appropriate for both original assembly and repair applications in industrial, defense, and heavy equipment environments.

Key Features

• 5/16 inch diameter by 1 inch overall length

Compatibility

Designed as an oversized replacement or assembly pin for applications requiring ASME B18.8.2 military specification dowel pins with a 5/16 inch nominal diameter and 1 inch length in alloy steel.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a press or mallet with a suitable drift. Ensure the receiving bore is clean and properly sized for an oversized pin before pressing. Do not hammer directly on the pin surface in a way that could damage the end geometry or alter the bore. Follow applicable facility safety and lockout/tagout procedures before servicing any machinery that requires pin removal or installation.
