Value Collection SF043056 Precision Dowel Pin Grade 8

Product Description

The VALUE COLLECTION SF043056 is a precision dowel pin used to locate, align, and secure mating components in machined assemblies. Made from alloy steel at Grade 8, this pin measures 0.5 inches in diameter and 1.5 inches in overall length. It carries a hardness rating of 50-58 HRC and a double-shear breaking strength of 51,000 pounds, making it suitable for high-load, close-tolerance applications. One end is beveled and one end is rounded, which assists with controlled insertion into bored or reamed holes. Machinists, tool and die technicians, and maintenance mechanics install this type of pin in jigs, fixtures, dies, and precision assemblies.

This dowel pin is used in industrial and manufacturing environments where repeatable part alignment and tight positional tolerances are required. Typical applications include fixture plates, mold components, machine bases, and press tooling where hole-to-hole alignment must be maintained across assembly and disassembly cycles. The diameter tolerance of 0.0002 inches ensures consistent fit in reamed or precision-bored holes. It conforms to ASME B18.8.2, the standard governing hardened ground machine dowel pins commonly specified on engineering drawings in both light manufacturing and heavy industrial settings.

Key Features

• Grade 8 alloy steel construction with 50-58 HRC surface hardness for wear and shear resistance
• Double-shear breaking strength of 51,000 pounds for high-load alignment applications
• Diameter tolerance of 0.0002 inches for precise fit in reamed or bored holes
• One beveled end and one rounded end for controlled, damage-free insertion
• Conforms to ASME B18.8.2 for use on drawings and assemblies requiring a recognized fastener standard

Compatibility

Designed as an OEM-style precision dowel pin for use in any application specifying an ASME B18.8.2 hardened ground machine dowel pin with a 0.5-inch diameter and 1.5-inch length.

Installation Notes

Installation should be performed by a qualified machinist or maintenance mechanic. Receiving holes must be reamed or precision-bored to the mating tolerance specified on the engineering drawing before pin installation. De-energize and lock out all equipment before inserting or removing dowel pins in active machinery. Use an arbor press rather than a hammer to avoid damaging the pin or bore during press-fit installation.
