Bridgeport 11011545 Locking Socket Set Screw Milling Machine

Product Description

The BRIDGEPORT 11011545 is a locking socket set screw designed for use in Bridgeport milling machine assemblies. Threaded at 1/4-32 with a 1/8-inch length, this screw serves as a securing fastener within the lower housing of 2J and J-Head style machines. It prevents unwanted movement or loosening of internal components during machine operation. Installation is performed by qualified machine tool technicians or millwrights during scheduled maintenance or component replacement. The fine 1/4-32 thread pitch provides precise engagement and reliable locking force in tight-tolerance housings.

This set screw is intended for use with Bridgeport I Series milling machines, specifically in the 2J and J-Head lower housing assemblies. It is a direct OEM-sourced replacement fastener used during spindle service, head rebuilds, or general preventive maintenance procedures. Shops running Bridgeport knee mills will encounter this fastener when servicing the lower head housing. It is sold individually, making it suitable for targeted single-point repairs without requiring a bulk hardware purchase.

Installation Notes

Installation is typically performed by a machine tool technician or millwright. Before servicing, power down the machine and follow lockout/tagout procedures in accordance with applicable OSHA standards. Use the correct hex key size to avoid rounding the socket drive. Do not overtighten, as the fine 1/4-32 thread is susceptible to damage in aluminum or cast iron housings if excessive torque is applied without reference to OEM specifications.
