Boneham P4016IO Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM P4016IO is a press fit headless drill bushing used to guide cutting tools with precision in jig and fixture applications. Manufactured from steel, this bushing features an inside diameter of 0.316 inches with a tolerance of +0.0001 to +0.0005 inches, a body outside diameter of 5/8 inches, and an overall length of 1 inch. The headless design sits flush with the jig plate surface, making it well suited for applications where a protruding head would interfere with the workpiece or tooling. It is a permanent, non-renewable bushing installed by press fit into a prepared drill jig plate.

This bushing is intended for use in precision drill jigs and fixtures in production machining and fabrication environments. The industry code P designation indicates a standardized size and tolerance class recognized across tooling and fixture applications. Machinists, tool and die makers, and fixture builders working in metal fabrication shops, job shops, and manufacturing facilities will find this bushing applicable wherever repeatable hole location and drill guidance are required in steel jig plates.

Compatibility

Designed as an OEM-style press fit headless drill bushing for use in steel drill jigs and fixtures requiring a standardized P-series bushing with a 0.316 inch inside diameter and 5/8 inch outside diameter.

Installation Notes

Installation is performed by pressing the bushing into a precisely reamed jig plate bore using an arbor press or hydraulic press. The receiving bore must be machined to the correct interference fit tolerance to ensure proper retention. This is a permanent, non-renewable bushing and is not designed for removal and replacement after installation. A tool and die maker or machinist should verify bore preparation before pressing to avoid damage to the bushing or jig plate.
