Key Features and Benefits

This screw’s captive washer eliminates the risk of losing small parts during installation. Its combination head accepts two common screwdriver types for field convenience. The nickel coating provides excellent resistance to moisture and industrial atmospheres. You can rely on this screw for consistent torque retention across multiple installations. The self-locking thread maintains tension even under continuous machinery vibration.

Installation and Application

You insert the screw into the PROFINET connector’s mounting hole and rotate clockwise. Use a standard Phillips screwdriver to tighten it to the recommended torque value. The screw engages with the connector housing and the device’s threaded insert simultaneously. For removal, simply rotate counterclockwise using either screwdriver type. The captive washer remains attached to the screw throughout its service life.

Typical Applications

Field technicians use this screw for mounting PROFINET connectors to ET 200SP interface modules. System integrators rely on it for securing communications cables in control panels. The screw also serves as a replacement part for worn or lost fasteners in existing installations.
