Bridgeport 12190083 Quill Stop Micro Screw

Product Description

The BRIDGEPORT 12190083 is a quill stop micro screw designed as a replacement hardware component for Bridgeport milling machines. The quill stop screw controls the depth-stop function on the quill assembly, allowing the operator to set and hold precise vertical travel limits during milling operations. This type of small-diameter fastener is a common wear or loss item on production floors and repair shops. It is installed and serviced by machinists and machine tool technicians as part of routine quill stop maintenance or rebuild work.

This micro screw is specified for use with Bridgeport I Series milling machines and fits the 2J and J-Head lower housing configurations. It is a direct OEM replacement part, making it appropriate for shops running original Bridgeport vertical knee mills where the quill stop assembly requires hardware replacement. The part ships individually and is suited for single-unit repair needs as well as bench-stock replenishment in machine shops and industrial maintenance operations.
