Value Collection SF043055 Precision Dowel Pin Alloy Steel

Product Description

The VALUE COLLECTION SF043055 is a precision dowel pin manufactured from alloy steel to Grade 8 material specifications. The pin measures 0.5 inches in diameter and 1.25 inches in overall length, and is designed to locate, align, or retain mating components with tight positional tolerance. Diameter tolerance is held to 0.0002 inches, making this pin suitable for applications that demand repeatable, close-tolerance alignment. End configuration is one beveled end and one rounded end per ASME B18.8.2. Hardness is rated at 50-58 HRC, providing high resistance to deformation under load. Machinists, tool and die makers, and maintenance technicians install this type of pin in fixtures, assemblies, and mating bores.

This dowel pin is appropriate for use in machine tool fixtures, jigs, mold and die sets, and general precision assembly applications. It performs in environments where component alignment must be maintained under repeated assembly and disassembly cycles. The combination of hardened alloy steel construction and close diameter tolerance makes it a standard choice for production tooling and maintenance applications where positional accuracy is critical. Sold individually, with a minimum order quantity of 10 pieces.

Key Features

• Diameter tolerance of 0.0002 inches for close-tolerance bore fit
• Hardness of 50-58 HRC resists deformation under load
• One beveled end and one rounded end for guided entry during installation
• Grade 8 alloy steel construction for high strength applications
• Breaking strength of 51,000 pounds in double shear

Compatibility

Designed as a standard precision dowel pin per ASME B18.8.2, suitable for use in any application requiring a 0.5-inch diameter hardened alloy steel locating pin.

Installation Notes

Precision dowel pins are typically installed by machinists or maintenance technicians using a press or mallet with a suitable driver. The mating bore should be reamed to the appropriate tolerance class before installation to ensure proper fit. Always verify bore diameter and surface finish before pressing in the pin. Do not install in bores that show wear, deformation, or out-of-round conditions that could compromise alignment.
