Value Collection 245220PR Precision Dowel Pin 5/16x1-1/4 SS316

Product Description

The VALUE COLLECTION 245220PR is a precision dowel pin manufactured from Grade 316 stainless steel with a bright, uncoated finish. Measuring 5/16 inch in diameter and 1-1/4 inches in overall length, this pin is designed for accurate alignment and positioning of mating components in assemblies requiring tight tolerances. The beveled end aids in guided insertion, and the diameter tolerance of 0.0002 inches ensures consistent fit across repeat installations. It conforms to ASME B18.8.2 standards, making it suitable for applications where dimensional precision and corrosion resistance are both critical requirements.

This dowel pin is used in mechanical assemblies across industrial, manufacturing, and maintenance applications where precise component alignment is required. Grade 316 stainless steel offers elevated corrosion resistance compared to Grade 304, making it well suited for environments exposed to moisture, mild chemicals, or marine conditions. Machinists, tool and die technicians, and maintenance professionals install this type of pin in fixtures, jigs, dies, and structural assemblies where repeatable positioning is essential.

Compatibility

Designed as an OEM-style precision alignment pin for use in mechanical assemblies, fixtures, jigs, and dies requiring ASME B18.8.2 compliant dowel pins with a 5/16 inch diameter.

Installation Notes

Precision dowel pins are typically installed by machinists or maintenance technicians using an arbor press or hand press to seat the pin into a reamed hole. Ensure the receiving hole is reamed to the correct tolerance to achieve the intended interference or slip fit before installation. Never strike the pin directly with a hammer, as this can damage the pin surface or distort the hole. Verify all mating components are properly aligned and free of debris before driving the pin into position.
