Value Collection IDP416-250-3.000-F09 Dowel Pin Ss 416

Product Description

The VALUE COLLECTION IDP416-250-3.000-F09 is a precision dowel pin machined from Grade 416 stainless steel with a passivated finish. It measures 0.25 inches in diameter and 3 inches in overall length, with a beveled end type for guided insertion. The diameter tolerance is held to 0.0000 to 0.0002 inches, making it suitable for close-tolerance alignment and locating applications. Hardness is rated at 36-42 HRC per ASTM A380-88. This pin is used by machinists, toolmakers, and maintenance technicians who need reliable, corrosion-resistant alignment components in precision assemblies.

This dowel pin is suited for jigs, fixtures, molds, dies, and mechanical assemblies where accurate part alignment and repeatability are required. The Grade 416 stainless steel construction provides good corrosion resistance and machinability, making it a practical choice in environments where mild corrosion exposure is a concern. The passivated finish further improves surface cleanliness and corrosion resistance, which is especially relevant in food processing, pharmaceutical, and clean-room adjacent manufacturing settings. The beveled end eases alignment during assembly and reduces risk of galling during insertion.

Compatibility

Designed as a precision locating pin for use in jigs, fixtures, dies, molds, and general mechanical assemblies requiring a 0.25-inch diameter dowel pin with close-tolerance fit.

Installation Notes

Precision dowel pins are typically installed by machinists or maintenance technicians using an arbor press or light mallet to drive the pin into a reamed or precision-bored hole. Always ensure the receiving bore is clean, properly sized, and deburred before installation to maintain the intended fit class. Do not force the pin into an undersized hole, as this can damage the bore or deform the pin. Follow all applicable shop safety and machine guarding procedures when pressing pins into assemblies.
