Value Collection SF043054 Dowel Pin 1/2x1 in Alloy Steel Gr8

Product Description

The VALUE COLLECTION SF043054 is a precision dowel pin designed for accurate alignment and location of mated components in mechanical assemblies. Machined from Grade 8 alloy steel and hardened to 50-58 HRC, this pin delivers the strength and dimensional consistency required for high-load, close-tolerance applications. The pin measures 0.5 inches in diameter and 1 inch in overall length, with a diameter tolerance of 0.0002 inches for precise fit in reamed holes. One end is beveled and one end is rounded, following ASME B18.8.2 standards. It is installed by machinists, toolmakers, and maintenance technicians working on jigs, fixtures, dies, and machine components.

This dowel pin is suited for use in precision assembly applications where accurate part registration is critical. Typical installations include machine tool fixtures, die sets, mold bases, and general industrial machinery where repeatable alignment between mating parts is required. The Grade 8 alloy steel construction handles high shear loads, with a rated double-shear breaking strength of 51,000 pounds. This pin is sold individually, with a minimum order quantity of 10 units.

Key Features

• Grade 8 alloy steel construction with 50-58 HRC hardness for high shear and wear resistance
• Diameter tolerance of 0.0002 inches for close-tolerance, precision-fit applications
• Double-shear breaking strength of 51,000 pounds
• One beveled end and one rounded end per ASME B18.8.2
• Compliant with ASME B18.8.2 fastener standard

Compatibility

Designed as an OEM-style replacement or standard-fit precision dowel pin for mechanical assemblies requiring ASME B18.8.2 compliant 0.5-inch diameter locating pins.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a press or mallet into a precision-reamed hole. Ensure the receiving hole is reamed to the appropriate tolerance before pressing the pin to avoid galling or damage to mating surfaces. De-energize and lock out all equipment before servicing any assembly containing dowel pins. Refer to applicable machinery safety standards and shop procedures during installation and removal.
