Value Collection IDP416-125-250-F09 Precision Dowel Pin

Product Description

The VALUE COLLECTION IDP416-125-250-F09 is a precision dowel pin machined from Grade 416 stainless steel with a passivated finish. It measures 1/8 inch in diameter and 1/4 inch in overall length. The beveled end type allows for guided, controlled insertion into precision-bored holes. Hardness is rated at 36-42 HRC, providing resistance to wear and deformation under load. The passivated surface treatment, performed to ASTM A380-88, removes free iron and surface contaminants to improve corrosion resistance. This pin is used by machinists, tool-and-die makers, and assembly technicians for locating and aligning mating components in precision assemblies.

This dowel pin is suited for light-duty precision alignment applications in manufacturing, tooling, and mechanical assembly environments. The Grade 416 stainless steel construction makes it appropriate for applications where mild corrosion resistance is required alongside good machinability. The tight diameter tolerance of 0.0000 to 0.0002 inches ensures accurate and repeatable component registration in production and maintenance settings. It is sold individually but carries a minimum order quantity of 50 units.

Key Features

• Grade 416 stainless steel construction with 36-42 HRC hardness for wear resistance
• Passivated finish per ASTM A380-88 for improved corrosion resistance
• Diameter tolerance of 0.0000 to 0.0002 inches for precision fit
• Beveled end type for guided insertion into close-tolerance bores
• Compact size: 1/8 inch diameter x 1/4 inch length for tight-space applications

Compatibility

Designed as an OEM-style precision locating pin for use in mechanical assemblies requiring close-tolerance stainless steel dowels in 1/8 inch diameter bores.

Installation Notes

Installation is typically performed by machinists or mechanical assembly technicians using a pin press or soft-faced mallet to avoid deforming the pin or bore. Always ensure the receiving hole is reamed to the correct tolerance before pressing the pin. Disable or de-energize any equipment before servicing assemblies that contain dowel pins. Do not force a pin into an undersized bore, as this can cause bore damage or pin fracture.
