Value Collection SF043032 Precision Dowel Pin 1/4x1-1/4 in

Product Description

The VALUE COLLECTION SF043032 is a precision dowel pin designed for tight-tolerance alignment and locating applications in machined assemblies. Made from alloy steel at Material Grade 8, this pin meets ASME B18.8.2 standards and delivers a hardness rating of 50-58 HRC. The 1/4-inch diameter and 1-1/4-inch overall length make it well suited for close-fit holes in dies, jigs, fixtures, and precision machine components. One end is beveled for easy insertion and the opposite end is rounded. Machinists, toolmakers, and maintenance mechanics working with precision assemblies typically install this type of pin.

This dowel pin is used in industrial manufacturing and maintenance settings where accurate part-to-part alignment is critical. Typical applications include locating mating components in die sets, fixture plates, and machine bases. The Grade 8 alloy steel construction provides the strength and hardness needed to resist shear forces in demanding production environments. It is packaged as a single pin with a minimum order quantity of 100 units, making it appropriate for production-floor stocking or MRO replenishment.

Key Features

• ASME B18.8.2 compliant precision dowel pin for standardized fit and interchangeability
• Grade 8 alloy steel construction with 50-58 HRC hardness for high wear and shear resistance
• Diameter tolerance of 0.0002 inches for accurate locating in close-tolerance bores
• 12,800 pounds breaking strength measured in double shear
• One beveled end and one rounded end for controlled installation and flush seating
• 1/4-inch diameter by 1-1/4-inch length suits a wide range of standard fixture and die applications

Compatibility

Designed as an ASME B18.8.2 standard precision dowel pin, compatible with any bored hole or reamed hole application specifying a 1/4-inch nominal diameter precision pin in alloy steel at Grade 8.

Installation Notes

Precision dowel pins are installed by toolmakers or maintenance machinists using an arbor press or similar controlled-force tool — never hammer directly onto the pin face, as this can damage the ground surface or alter tolerances. Confirm the receiving hole is reamed to the correct tolerance and is free of burrs, chips, and contaminants before pressing the pin into place. Follow applicable shop safety practices and OSHA general machine-guarding requirements when working with presses.
