Holo-krome 02083 Pull Out Dowel Pin 8x70mm Alloy Steel

Product Description

The HOLO-KROME 02083 is a standard pull out dowel pin designed for precise locating and alignment applications in mechanical assemblies. Manufactured from Grade 8 alloy steel with a black luster finish, this pin delivers hardened strength and corrosion resistance suited to demanding industrial environments. It measures 8 mm in diameter with an overall length of 70 mm, and features one beveled end and one rounded end to facilitate controlled insertion and retrieval. The pull out design allows removal from blind holes without the need for through-hole access, which is a common requirement in tooling, fixtures, and machine component alignment. Licensed machinists, toolmakers, and maintenance technicians are the primary installers.

This dowel pin is used in precision fixturing, jig and die alignment, and machine component assembly where repeatable positioning is critical. The 8 mm diameter and 70 mm length make it well-suited for medium-duty tooling plates and structural alignment applications in both production and maintenance settings. It conforms to ASME B18.8.5M, meaning it meets standardized dimensional and tolerance requirements recognized in industrial manufacturing environments across North America.

Key Features

• Grade 8 alloy steel construction for high shear strength and hardness
• Black luster finish provides basic corrosion resistance in dry or lightly oiled environments
• One beveled end and one rounded end for guided insertion and pull-out retrieval
• Diameter tolerance of -0.0001 to 0.0001 inches for tight, repeatable press-fit locating
• Conforms to ASME B18.8.5M dimensional standard
• Pull out groove enables extraction from blind holes without reverse-side access

Compatibility

Designed as an OEM-style replacement or direct-use standard dowel pin for applications conforming to ASME B18.8.5M, including precision fixtures, tooling plates, jigs, dies, and machine assemblies requiring an 8 mm nominal diameter locating pin.

Installation Notes

Installation is typically performed by toolmakers or maintenance machinists using a press or mallet with a properly sized drift. The receiving hole must be reamed to the appropriate H7 or equivalent tolerance to achieve the intended press fit. Always clean and deburr the hole before insertion to avoid galling the pin surface. Use the pull out groove with an appropriate extractor tool when removing the pin from blind holes rather than driving from behind.
