Zago Sealing Screws MS Parts List

ZAGO Sealing Screws MS3212/3213 Parts List

ZAGO’s Phillips Pan Head Seal Screws are easy to install and designed to perform under pressure. These fasteners combine reliable fastening with environmental sealing, all in one component. Machine screws integrate a wide, low-profile pan head with a centered Phillips drive for ease of installation. An elastomeric O-ring on the underside of the head forms a 360-degree hermetic seal, eliminating failure due to fluid ingress.

This unified design cuts the need for secondary washers, gaskets, and sealants, reducing assembly time, lowering total part count, and improving long-term reliability.

Designed for mission-critical applications, these pressure-sealing fasteners deliver both mechanical fastening and environmental sealing, performing under pressure and exposure to fluids and particulates. They are ideal for aerospace, medical devices, robotics, and defense, among other uses.

All components are fully customizable (see detail below) and engineered-to-order to ensure optimal performance. ZAGO’s team of US-based engineers is available to share their expertise and help make the best choice for your application.
