Value Collection 536034PR Precision Dowel Pin 4x30mm Grade 8

Product Description

The VALUE COLLECTION 536034PR is a precision dowel pin engineered for accurate alignment and location of mating components in mechanical assemblies. Manufactured from alloy steel to Grade 8 specifications, this pin measures 4 mm in diameter and 30 mm in overall length with rounded ends for smooth insertion. It carries a bright, uncoated finish and conforms to DIN 6325 and ISO 8734 fastener standards, ensuring dimensional consistency for use in tooling, fixtures, jigs, and precision machine components. Installation is performed by maintenance machinists, toolmakers, and mechanical assemblers working in manufacturing and industrial maintenance environments.

This dowel pin is suited for applications requiring tight tolerances and repeatable part location. Typical installations include press-fit or slip-fit configurations in tool-and-die work, fixture plates, mold assemblies, and precision machinery. The Grade 8 alloy steel construction provides the hardness and shear strength needed for high-load, close-tolerance alignment tasks. Rounded ends reduce the risk of burring during insertion and allow the pin to guide smoothly into bored holes. This SKU is sold individually, with a minimum order quantity of 100 pieces.

Key Features

• Conforms to DIN 6325 and ISO 8734 fastener standards for internationally recognized dimensional accuracy
• Grade 8 alloy steel construction for high hardness and shear strength in demanding alignment applications
• Rounded end type promotes clean, burr-free insertion into precision-bored holes
• Bright, uncoated finish maintains tight diameter tolerances without coating buildup
• 4 mm diameter by 30 mm length suits a wide range of standard tooling and fixture configurations

Compatibility

Designed as a standard-dimension replacement or new-installation precision dowel pin for any mechanical assembly or fixture application requiring DIN 6325 or ISO 8734 compliant 4 mm x 30 mm pins.

Installation Notes

Precision dowel pins are typically installed by machinists or tool-and-die technicians using an arbor press or mallet, depending on the fit class of the bored hole. Ensure the receiving hole is reamed to the appropriate tolerance for the intended press-fit or slip-fit application before installation. De-energize and lock out all machinery before servicing any assembly containing dowel pins. Do not force a pin into an undersized hole, as this can cause hole damage or pin shear.
