Value Collection SF043036 Precision Dowel Pin Alloy Steel

Product Description

The VALUE COLLECTION SF043036 is a precision dowel pin manufactured from alloy steel to Grade 8 material standards and certified to ASME B18.8.2. It measures 0.25 inches in diameter and 2.5 inches in overall length, with a tight diameter tolerance of 0.0002 inches that ensures accurate, repeatable alignment in close-tolerance assemblies. The pin features one beveled end and one rounded end, a standard configuration that aids insertion into reamed holes while providing a positive seating surface. Hardness is rated at 50-58 HRC, and double-shear breaking strength is 12,800 pounds. Machinists, tool-and-die technicians, and maintenance mechanics install this pin in production tooling, fixtures, jigs, and mechanical assemblies.

This dowel pin is suited for applications requiring precise hole-to-hole or component-to-component alignment in industrial and manufacturing environments. Typical use cases include fixture plates, die sets, mold components, and machine bases where consistent, high-precision locating is critical. The 50-58 HRC hardness range supports use in high-load and high-cycle applications where a softer pin would wear or deform prematurely.

• Conforms to ASME B18.8.2 fastener standard
• 0.25-inch diameter by 2.5-inch overall length

Compatibility

Designed as an OEM-style precision locating pin for industrial fixtures, tooling plates, die sets, and mechanical assemblies requiring ASME B18.8.2 compliant precision dowel pins in 0.25-inch diameter.

Installation Notes

Precision dowel pins are typically installed by machinists or tool-and-die technicians using a press or mallet and a properly reamed receiver hole sized to the required fit class. De-energize and lock out all equipment before servicing any assembly containing dowel pins. Do not hammer pins into un-reamed or undersized holes, as this will damage the pin surface and compromise alignment accuracy. Follow applicable shop standards and the ASME B18.8.2 specification for hole preparation and fit class selection.
