Value Collection 536031PR Precision Dowel Pin 4x22mm Grade 8

Product Description

The VALUE COLLECTION 536031PR is a precision dowel pin manufactured from alloy steel to Grade 8 specifications. It measures 4 mm in diameter and 22 mm in overall length with a rounded end type and a bright, uncoated finish. Produced to DIN 6325 and ISO 8734 standards, this pin is designed for tight-tolerance alignment and locating applications in machined assemblies. Machinists, tool-and-die makers, and maintenance technicians install these pins where precise hole-to-hole registration is required and positional accuracy cannot be compromised.

This dowel pin is suited for use in metal fabrication, fixture building, die sets, jigs, and general precision assembly work. Its standardized diameter and length make it a direct fit wherever DIN 6325 or ISO 8734 compliant pins are specified. The Grade 8 alloy steel construction provides the hardness and shear strength needed in repetitive-load and high-cycle applications across both production and maintenance environments.

Key Features

• Conforms to DIN 6325 and ISO 8734 fastener standards for interchangeability in precision assemblies
• Grade 8 alloy steel construction for high hardness and shear resistance
• Bright uncoated finish maintains dimensional accuracy without coating buildup
• Rounded end type eases insertion into close-tolerance bored holes
• 4 mm diameter x 22 mm length for compact, precise locating applications

Compatibility

Designed as a standard-compliant replacement or replenishment pin for any application specifying a DIN 6325 or ISO 8734 precision dowel pin at 4 mm diameter and 22 mm length.

Installation Notes

Precision dowel pins are typically pressed or driven into reamed holes by machinists or maintenance technicians using an arbor press or dead-blow mallet. Always ream receiving holes to the appropriate tolerance class before installation to achieve the intended fit. Power down and lock out any machinery before removing or installing locating pins in active fixtures or dies. Do not force pins into undersized holes, as this can compromise bore geometry and reduce holding accuracy.
