Bridgeport 12191620 Tee Bolt Series I Milling Machine

Product Description

The BRIDGEPORT 12191620 is a 1/2-13 tee bolt designed as a hardware component for Bridgeport Series I milling machines. Tee bolts are critical fastening hardware used to secure workholding fixtures, vises, and tooling to the machine table T-slots. This bolt interfaces with the 2J and J-Head lower housing, providing the clamping force needed to keep setups rigid during milling operations. At 0.75 pounds, it is a direct replacement-style component for shops maintaining or rebuilding Series I mills. Installation is straightforward but proper torque and fitment are essential to maintain workholding integrity and machine accuracy.

This tee bolt is intended for use with Bridgeport Series I milling machines, specifically the 2J and J-Head lower housing configurations. It is a standard hardware replacement part suited for machine shops, vocational facilities, and industrial maintenance environments where Series I Bridgeport mills are in active service. Machinists and millwrights performing preventive maintenance, table slot restoration, or fixture upgrades will find this a direct fit component.
