Leak Proof Screws
Leak Proof Screws are formed with an undercut groove to fit the O-ring. A fastened unit becomes leak proof because the fastening torque applied onto the screw and the O-ring seals the junction. Leak Proof Screws are generally applied to oil pressure systems, motors, and other apparatus that require sealing.
