Boneham SF328FC Slip-fixed Drill Bushing 0.166 in Id

Product Description

The BONEHAM SF328FC is a slip-fixed drill bushing designed for precision hole location in jig and fixture applications. Built to SF industry standards, it features a 0.166 inch inside diameter sized for a No. 19 wire gauge drill, a 0.500 inch body outside diameter, and a 0.500 inch length under the head. Constructed from steel and hardened to 60 to 65 HRC, the SF328FC delivers the wear resistance required for repetitive drilling operations in production environments. Installation and removal are tool-free by design, making this bushing well suited for setups that require frequent bushing changes between operations.

This bushing is intended for use in drill jigs and machining fixtures where accurate and repeatable hole placement is required. The headed design provides positive seating against the jig plate, and the renewable construction allows the bushing to be replaced without retiring the fixture body. Typical applications include metalworking production lines, aerospace fabrication shops, and general machine shops running multi-operation jig setups. The LS-1 compatible lock screw interface ensures the bushing stays positively located during the drilling cycle.

Key Features

• SF industry code slip-fixed design allows tool-free removal and replacement during fixture changeovers
• 0.166 inch (No. 19 wire gauge) inside diameter with a tight tolerance of plus 0.0001 to plus 0.0004 inches for precise drill guidance
• Steel construction hardened to 60 to 65 HRC for extended wear life in high-cycle drilling operations
• Headed design with 51/64 inch head outside diameter and 1/4 inch head height for positive seating in the jig plate
• Renewable bushing construction supports fixture longevity by allowing bushing replacement independent of the liner
• Compatible with LS-1 lock screw for positive retention during drilling

Compatibility

Designed as an OEM-style renewable slip-fixed drill bushing conforming to ANSI standards for use with LS-1 compatible lock screws in standard drill jig liner applications.

Installation Notes

Slip-fixed bushings are installed and removed by hand rotation and should be seated into a compatible press-fit liner already installed in the jig plate. Ensure the fixture is secured and the workpiece is properly clamped before beginning any drilling operation. Confirm lock screw engagement before applying drill pressure. Machinist or toolmaker installation is typical for jig and fixture setups of this type.
