Value Collection 536028PR Precision Dowel Pin 4x16mm Grade 8

Product Description

The VALUE COLLECTION 536028PR is a precision dowel pin designed for accurate locating and alignment of mating components in mechanical assemblies. Manufactured from alloy steel to Material Grade 8, this pin meets DIN 6325 and ISO 8734 standards, making it a reliable choice for high-tolerance applications. The pin measures 4 mm in diameter and 16 mm in overall length, with a bright, uncoated finish and rounded end geometry. It is suited for use in jigs, fixtures, dies, molds, and precision machine components where repeatable positioning is critical. Machinists, toolmakers, and maintenance technicians working in industrial and manufacturing environments are the primary installers.

This dowel pin is used in applications requiring tight positional tolerances between assembled parts. Its DIN 6325 and ISO 8734 compliance makes it interchangeable with other pins produced to these standards across tooling, fixture, and machine-frame assemblies. The rounded end type allows for guided insertion into reamed or ground holes during assembly and disassembly cycles. It is appropriate for use in both light-duty and heavy-duty mechanical assemblies where component alignment must be maintained under load or vibration.

Key Features

• Alloy steel construction to Material Grade 8 for high strength and hardness
• Conforms to DIN 6325 and ISO 8734 fastener standards for broad interchangeability
• 4 mm diameter and 16 mm overall length for precise dimensional fitment
• Rounded end type for easier alignment during insertion into precision-bored holes
• Bright, uncoated finish suitable for controlled indoor environments

Compatibility

Designed as a standard DIN 6325 and ISO 8734 compliant precision dowel pin suitable for use in any mechanical assembly requiring a 4 mm diameter locating pin in this length class.

Installation Notes

Precision dowel pins are typically installed by machinists or toolmakers using a press fit into reamed or ground holes held to H7 or m6 tolerance as specified by the applicable standard. Power down and de-energize all associated machinery before servicing or replacing dowel pins in live assemblies. A hydraulic or arbor press is the recommended installation tool; driving pins with a hammer risks galling the bore or damaging the pin. Consult the relevant engineering drawing or tolerance standard before selecting hole fit class for the application.
