Value Collection 551306PR Dowel Pin 4mm X 40mm Ss Grade 316

Product Description

The VALUE COLLECTION 551306PR is a standard pull out dowel pin machined from Grade 316 stainless steel with a bright, uncoated finish. Dowel pins of this type are used to precisely align mating components, fixtures, jigs, and assemblies in industrial and mechanical applications. At 4 mm in diameter and 40 mm in overall length, this pin meets DIN 7 EN ISO 2338 dimensional standards, ensuring interchangeability with tooling and components designed to that specification. The rounded end type aids in guided insertion during assembly. Grade 316 stainless steel provides strong resistance to corrosion and chemical exposure compared to standard 303 or 304 grades, making it appropriate for wet, marine, or chemically aggressive environments.

This dowel pin is suited for use in precision machining, toolmaking, fixture building, and mechanical assembly where tight positional tolerances are required. The DIN 7 EN ISO 2338 standard makes it compatible with metric-dimensioned bores and mating hardware used widely in manufacturing and industrial maintenance. It is commonly installed by machinists, tool and die makers, millwrights, and maintenance mechanics working on production equipment, dies, molds, or structural assemblies that require repeatable alignment between parts.

Key Features

• Meets DIN 7 EN ISO 2338 fastener standard for metric interchangeability
• Grade 316 stainless steel construction for enhanced corrosion resistance
• Bright, uncoated finish maintains close dimensional tolerances
• Rounded end type for guided, accurate insertion into bores
• 4 mm diameter x 40 mm overall length for compact alignment applications

Compatibility

Designed as a standard-dimensioned replacement or service pin for metric tooling, fixtures, jigs, and mechanical assemblies requiring a DIN 7 EN ISO 2338 compliant 4 mm pull out dowel pin.

Installation Notes

Installation is typically performed by machinists or millwrights using a press or mallet with a proper driver to avoid damage to the pin or bore. Ensure the receiving bore is clean, deburred, and dimensioned to the correct tolerance class per DIN 7 EN ISO 2338 before pressing the pin into place. Pulling or extracting the pin should be done with an appropriate puller tool to prevent bore damage. Do not force an oversized pin into an undersized bore.
