Value Collection IDP416-187-1.250-F09 Precision Dowel Pin

Product Description

The VALUE COLLECTION IDP416-187-1.250-F09 is a precision dowel pin machined from Grade 416 stainless steel and finished with a passivated surface treatment per ASTM A380-88. It measures 3/16 inches in diameter with an overall length of 1.25 inches. The pin features a beveled end type for guided insertion and holds a hardness rating of 36-42 HRC, making it suitable for demanding alignment and locating applications. Machinists, toolmakers, and maintenance technicians install this pin wherever tight positional tolerances are required in assemblies, jigs, fixtures, and precision mechanical components.

This dowel pin is used in industrial and manufacturing environments where repeatable, accurate part alignment is critical. Typical applications include fixture building, mold and die work, machine tool assemblies, and precision component registration. The passivated finish improves corrosion resistance, making it appropriate for environments where mild chemical exposure or moisture is a concern. The Grade 416 stainless construction provides a balance of machinability and surface hardness suitable for moderate-load locating duties in both production and maintenance settings.

Key Features

• Grade 416 stainless steel construction with passivated finish per ASTM A380-88
• Hardness rated at 36-42 HRC for reliable locating under load
• Diameter tolerance of 0.0000 to 0.0002 inches for precision fit
• Beveled end type for easier alignment and guided insertion
• Compact 3/16 x 1.25 inch size suits tight-clearance assemblies

Compatibility

Designed as an OEM-style precision locating pin for use in jigs, fixtures, molds, dies, and mechanical assemblies requiring a 3/16 inch diameter dowel with a 1.25 inch overall length and a passivated stainless steel finish.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a press or mallet with a suitable driver. The mating hole should be reamed to the appropriate tolerance before pressing the pin to avoid galling or distortion. Ensure the assembly is de-energized and secured before installing or removing locating pins in powered equipment. Do not strike the beveled end directly, as this may deform the lead and compromise fit.
