Boneham SFT5616MH Slip-fixed Bushing 0.625 in Id Steel

Product Description

The BONEHAM SFT5616MH is a slip-fixed renewable drill bushing designed for use in jig plates and fixture tooling applications. It features an inside diameter of 0.625 inches with a close tolerance of +0.0001 to +0.0005 inches, a body outside diameter of 0.875 inches, and a length under head of 1 inch. The head outside diameter measures 1.25 inches with a head height of 0.375 inches. Constructed from steel, this headed bushing is held in place using a lock screw and is classified under industry code SF. It is installed and serviced by machinists, toolmakers, and fixture builders working with precision drill jig assemblies.

This bushing is suited for slip-fixed installations where the bushing must be removable for tool changes or inspection while remaining positively locked during drilling operations. The renewable design allows the bushing to be swapped out independently of the liner bushing pressed into the jig plate, making it a practical choice for production fixtures that see repeated use across multiple part runs. The SF industry code designation identifies the head style and dimensional series per standard bushing conventions.

Key Features

Compatibility

Designed for use with LS-TW-7 compatible lock screws. Fits standard liner bushings accepting a 0.875-inch body outside diameter in SF-series slip-fixed configurations.

Installation Notes

Installation is performed by machinists or toolmakers during jig and fixture assembly or maintenance. The slip-fixed bushing seats into a pressed liner bushing in the jig plate and is secured with the appropriate lock screw before drilling operations begin. Always ensure the mating liner bushing bore is clean and free of chips before inserting the slip-fixed bushing. Remove and inspect the bushing regularly in high-cycle applications to maintain hole location accuracy.
