COVID-19: ZAGO Sealing Fasteners Available for Ventilator Manufacturing. Learn More.

Slotted pan head machine screws are made of steel for long lasting durability and dependability. Screws feature straight shank fasteners with external threads used for pre-tapped hole or nut assembly to form a mating thread. ZAGO’s machine screws are equipped with a resilient O-ring which creates a total barrier against foreign matter. If you are using generic screws rather than ZAGO’s self-sealing screws, then your equipment is at risk of being damaged beyond repair due to pressure or contamination. With ZAGO, you can customize your machine screws with our extensive selection of head, driver and thread types.
