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

Socket cap screws are widely used due to their space saving design (smaller head) and that they are able to handle higher torque. If you’re operating in tough conditions and you need fail-safe mechanisms to prevent disaster, then use ZAGO’s self-sealing socket caps. These tough pieces of hardware are built to seal in/out any potential leaks. Our socket caps feature a unique O-ring which molds its shape to create a secure seal for your fastener.
