Boneham SF2016EV Slip-fixed Drill Bushing 0.157 in Id Steel

Product Description

The BONEHAM SF2016EV is a slip-fixed drill bushing designed for precision hole-location applications in jig and fixture work. Classified under bushing industry code SF, it features a 0.157 inch (No. 22 wire gauge) inside diameter with a tight tolerance of +0.0001 to +0.0004 inches, ensuring repeatable, accurate drill guidance. The body outside diameter is 0.3125 inches (5/16 inch) and the length under head is 1 inch. Constructed from steel with a counterbored head, this bushing seats into a drill jig plate and is locked in place with an LS-1 compatible lock screw. Machinists, toolmakers, and production fixture builders install this type of component as part of a renewable bushing system.

This slip-fixed bushing is suited for drill jig applications in both production and toolroom environments. The renewable design allows the bushing to be removed and replaced without disturbing the jig plate, making it practical for high-cycle drilling operations where bushing wear is a factor. The head outside diameter of 35/64 inch and head height of 1/4 inch provide positive seating against the jig plate surface. The counterbored configuration accommodates standard SF-style installation practices. This part is appropriate for metalworking and precision machining operations where positional accuracy of drilled holes is critical.

Key Features

• SF bushing industry code, slip-fixed style for use with a lock screw
• 0.157 inch inside diameter with +0.0001 to +0.0004 inch tolerance for precise drill guidance
• Steel construction for durability in production drilling applications
• Renewable bushing design allows in-plate replacement without rework
• Counterbored head seats flush or below jig plate surface as required
• LS-1 compatible lock screw interface for secure retention

Compatibility

Designed as an OEM-style replacement or new-installation slip-fixed drill bushing for SF-style jig and fixture plates requiring an LS-1 compatible lock screw.

Installation Notes

Installation is typically performed by machinists or toolmakers during jig plate assembly or bushing renewal. The jig plate must be properly bored to the SF-style press-fit counterbore specification before installation. Secure the bushing using an LS-1 compatible lock screw; do not attempt to retain the bushing by adhesive alone in applications subject to drill thrust loading. Follow applicable shop safety practices and de-energize any associated machinery before servicing drill fixtures.
