Value Collection 551297PR Dowel Pin 4mm X 30mm Ss Grade 316

Product Description

The VALUE COLLECTION 551297PR is a standard pull out dowel pin machined from Grade 316 stainless steel with a bright, uncoated finish. Measuring 4 mm in diameter and 30 mm in overall length, this pin is designed to align and locate mating components with close-tolerance repeatability. The rounded end type eases insertion and reduces the risk of bore damage during assembly. Grade 316 stainless steel provides strong corrosion resistance, making this pin suitable for applications exposed to moisture, mild chemicals, or outdoor environments. It meets DIN 7 EN ISO 2338 standards, ensuring dimensional consistency across mating parts and interchangeability with other conforming components.

This dowel pin is used in precision assembly applications across manufacturing, tooling, fixturing, and machine building. The DIN 7 EN ISO 2338 standard makes it a common choice for jigs, dies, and mechanical subassemblies where accurate part registration is critical. Grade 316 stainless construction suits food processing equipment, marine hardware, and similar environments where carbon steel or lower alloy grades would be inadequate. Machinists, toolmakers, and maintenance technicians are the typical installers. Sold individually, with a minimum order quantity of 10 units.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance compared to Grade 304
• Meets DIN 7 EN ISO 2338 standard for consistent dimensional tolerances and interchangeability
• Rounded end type for easier insertion and reduced bore edge damage
• Bright, uncoated finish maintains close dimensional tolerances without coating buildup
• 4 mm diameter x 30 mm overall length — compact profile for tight assembly envelopes

Compatibility

Designed for use in any application requiring DIN 7 EN ISO 2338 compliant standard pull out dowel pins with a 4 mm diameter bore and 30 mm engagement length.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a press, mallet, or pull-out extraction tool appropriate for the bore fit class. Ensure the receiving bore is clean, deburred, and dimensioned to the correct tolerance class per DIN 7 EN ISO 2338 before pressing the pin. Do not hammer directly on the pin face without a proper driver to avoid deforming the rounded end or damaging the bore. Pins should be inspected for surface defects or dimensional nonconformance before installation in precision assemblies.
