Value Collection 241130PR Precision Dowel Pin 3/16x7/8 Grade 8

Product Description

The VALUE COLLECTION 241130PR is a precision dowel pin used to locate, align, and retain mating components in mechanical assemblies. Manufactured from alloy steel at Grade 8, it carries a hardness rating of 50-58 HRC and a double-shear breaking strength of 7,200 pounds, making it appropriate for high-load positioning applications. The pin measures 3/16 inches in diameter with an overall length of 7/8 inches and holds a diameter tolerance of 0.0002 inches, ensuring tight, repeatable fits in precision-bored holes. One end is beveled and one end is rounded per ASME B18.8.2 standards. Machinists, tool and die makers, and maintenance technicians install this type of fastener in fixtures, jigs, dies, and general mechanical assemblies.

This pin is suited for use in industrial manufacturing environments where precise component alignment is required. Typical applications include machine tool fixtures, die sets, stamping tooling, and precision assembly jigs. The 3/16-inch diameter and 7/8-inch length fit standard precision-bored holes requiring a ground dowel pin to ASME B18.8.2 specification. The single-piece packaging is standard; this part carries a minimum order quantity of 100 units.

Key Features

• ASME B18.8.2 standard — ensures dimensional conformance for interchangeable use in precision fixtures
• 50-58 HRC hardness — resists wear and deformation under repeated loading and press-fit cycles
• 7,200-pound double-shear breaking strength — rated for high-load alignment and retention duties
• 0.0002-inch diameter tolerance — supports tight interference or transition fits in precision-bored holes
• One beveled end, one rounded end — eases insertion and reduces burring during assembly
• Alloy steel, Grade 8 construction — suitable for demanding industrial fastening and locating applications

Compatibility

Designed as an OEM-style replacement or standard stock dowel pin for precision mechanical assemblies requiring ASME B18.8.2 compliant ground pins with a 3/16-inch diameter and 7/8-inch overall length.

Installation Notes

Precision dowel pins are typically installed by machinists or maintenance technicians using an arbor press or mallet with a pin driver. The receiving hole should be finish-reamed to the appropriate tolerance class before installation to achieve the intended fit. Power down and de-energize any associated machinery before installing or removing dowel pins. Avoid driving pins directly with a hammer face, as this can damage the pin end and distort the bore.
