Value Collection 551300PR Dowel Pin 4mm X 32mm SS316

Product Description

The VALUE COLLECTION 551300PR is a standard pull out dowel pin manufactured from Grade 316 stainless steel with a bright, uncoated finish. Designed to DIN 7 EN ISO 2338 standards, this pin measures 4 mm in diameter and 32 mm in overall length with a rounded end type. Grade 316 stainless steel provides strong corrosion resistance, making this pin suitable for demanding environments where moisture, chemicals, or salt exposure are concerns. Licensed machinists, toolmakers, and maintenance technicians install these pins to maintain precise alignment between mating components such as fixtures, dies, jigs, and machine assemblies.

This dowel pin is used in general industrial, manufacturing, and maintenance applications where consistent part alignment and repeatable positioning are required. The DIN 7 EN ISO 2338 dimensional standard ensures compatibility with standard reamed hole tolerances. Typical applications include fixture plates, machine bases, press tooling, and mechanical assemblies where pull-out access from one side is the installation method. The rounded end eases insertion into close-tolerance holes without scoring bore walls.

Key Features

• Conforms to DIN 7 EN ISO 2338 dimensional standard for close-tolerance fit in reamed holes
• Grade 316 stainless steel construction for superior corrosion resistance in wet or chemical environments
• Bright, uncoated finish maintains precise dimensional tolerances without added coating thickness
• Rounded end type aids alignment during installation and reduces bore damage risk
• Standard pull out design allows removal from one side of the assembly

Compatibility

Designed for use in standard reamed holes conforming to DIN 7 EN ISO 2338 tolerances for 4 mm diameter dowel pins in industrial fixtures, machine components, and tooling assemblies.

Installation Notes

Dowel pins of this type are installed by qualified machinists or maintenance technicians using a press or mallet with a proper driver — never struck directly on the pin face. The receiving hole should be finish-reamed to the tolerance class specified by DIN 7 EN ISO 2338 before installation. Inspect hole and pin for debris or burrs before pressing to avoid galling. Ensure the assembly is secured and depressurized before removing or replacing alignment pins in active machinery.
