Boneham H268GH Press Fit Headed Drill Bushing Steel

Product Description

The BONEHAM H268GH is a Type H press fit headed drill bushing manufactured from steel for precision hole-location guidance in drilling operations. It features an inside diameter of 0.2055 inches (wire size No. 5) with a tight tolerance of +0.0001 to +0.0004 inches, ensuring accurate drill guidance and repeatable results. The body outside diameter is 13/32 inches, with a 1/2-inch length under the head. This bushing installs without a retaining liner, pressing directly into a jig plate, and is intended for permanent or semi-permanent fixture setups. Machinists, tool-and-die makers, and fixture builders working in precision manufacturing, metal fabrication, and industrial maintenance rely on this type of component for consistent drill placement across production runs.

The H268GH is suited for use in drill jigs and fixture plates where a headed, press-fit bushing is required to locate and guide twist drills or reamers at a fixed position. Its headed design keeps the bushing from being driven through the jig plate during operation. The 1/2-inch head outside diameter and 5/32-inch head height provide a secure shoulder against the plate surface. This bushing is appropriate for light- to medium-duty production and toolroom applications where the bushing is not intended to be replaced during the life of the fixture.

Compatibility

Designed as an OEM-style press fit headed drill bushing for use in standard drill jig plates and fixture assemblies that accept Type H bushings with a 13/32-inch body outside diameter.

Installation Notes

Press fit bushings are installed by tool-and-die makers or machinists using an arbor press or similar controlled-force pressing equipment — never a hammer alone, as this can damage the bore tolerance. The jig plate hole should be prepared to the appropriate press fit specification before installation. Once pressed in, this non-renewable bushing is not designed for removal and replacement without potential damage to the fixture plate. Always verify bore alignment and cleanliness before pressing the bushing into the plate.
