Value Collection IDP416-156-625-F09 Precision Dowel Pin

Product Description

The VALUE COLLECTION IDP416-156-625-F09 is a precision dowel pin machined from Grade 416 stainless steel with a passivated finish. It measures 5/32 inches in diameter and 5/8 inches in overall length, with a diameter tolerance held to 0.0000 to 0.0002 inches for tight, repeatable alignment. Hardness is rated at 36-42 HRC, providing solid resistance to wear and deformation under load. The beveled end aids in seating and reduces the risk of cross-alignment during assembly. Machinists, toolmakers, and maintenance technicians use this pin in precision fixtures, jigs, and mechanical assemblies where accurate component registration is critical.

This dowel pin is suited for applications requiring corrosion resistance combined with precise dimensional control. The Grade 416 stainless steel and ASTM A380-88 passivation treatment make it appropriate for use in food processing equipment, medical device fixtures, marine hardware, and general industrial tooling where both hygiene and dimensional accuracy matter. The beveled end style allows for straightforward hand-press or light press-fit installation into standard dowel-pin holes in metal and hardened components.

Key Features

• Grade 416 stainless steel construction with passivated finish per ASTM A380-88 for corrosion resistance
• Diameter tolerance of 0.0000 to 0.0002 inches for precision alignment fits
• Hardness of 36-42 HRC for wear resistance under repeated assembly and disassembly cycles
• Beveled end type for ease of entry and accurate seating in dowel holes
• Compact size — 5/32 inches diameter by 5/8 inches length — suitable for tight-clearance fixtures

Compatibility

Designed as a standard precision dowel pin replacement for use in jigs, fixtures, dies, and mechanical assemblies requiring a 5/32-inch diameter pin hole and 5/8-inch engagement length.

Installation Notes

Installation is typically performed by machinists or toolmakers using a hand press or arbor press — never drive precision dowel pins with a hammer, as this risks damaging the pin's diameter tolerance or the receiving bore. Ensure the mating hole is cleaned, deburred, and dimensioned to accept a press fit before installation. Power down and de-energize any equipment before servicing fixtures or assemblies containing these pins. Follow applicable shop safety standards and fastener torque guidelines for the surrounding assembly.
