Value Collection 536027PR Precision Dowel Pin 4x18mm Grade 8

Product Description

The VALUE COLLECTION 536027PR is a precision dowel pin manufactured from alloy steel to Grade 8 specifications. It measures 4 mm in diameter and 18 mm in overall length, with rounded ends and a bright uncoated finish. Conforming to DIN 6325 and ISO 8734 standards, this pin is designed for tight-tolerance locating and alignment applications in machined assemblies. Machinists, tool and die makers, and maintenance technicians install these pins where accurate, repeatable part positioning is required. The bright finish indicates no supplemental coating, keeping dimensional tolerances consistent straight from the manufacturer.

Precision dowel pins of this size and grade are used in jigs, fixtures, molds, dies, and general mechanical assemblies where two or more components must be held in precise alignment. The 4 mm diameter and 18 mm length make this pin suitable for compact assemblies in light industrial and machine shop environments. These pins are commonly installed in press-fit or slip-fit bores depending on the designed hole tolerance. This SKU is sold as a single pin with a minimum order quantity of 100 units.

Key Features

• Meets DIN 6325 and ISO 8734 precision dowel pin standards
• Grade 8 alloy steel construction for high strength and hardness
• Bright uncoated finish maintains close dimensional tolerances
• Rounded ends facilitate accurate alignment during installation
• 4 mm diameter x 18 mm length for compact fixture and die applications

Compatibility

Designed as a standard DIN 6325 and ISO 8734 precision dowel pin for use in machined bores requiring tight positional tolerances in jigs, fixtures, molds, and mechanical assemblies.

Installation Notes

Precision dowel pins are typically installed by machinists or toolmakers using an arbor press or mallet, depending on the designed bore fit. Inspect bore diameter and surface finish before installation to ensure proper fit class. Never drive a dowel pin into an undersized or misaligned bore, as this can damage the bore or shear the pin. Always consult applicable engineering drawings for required fit tolerances and press-in force guidelines.
