Product details

What This Lockwasher Does

The Amphenol RF 903-10409-1 is a gold-plated lockwasher designed for use with SMB and SMC bulkhead jacks. Its job is to provide a positive mechanical lock between the jack's mounting nut and the panel face, preventing the connector from loosening under vibration or thermal cycling. The gold finish on both the body and the washer itself gives it corrosion resistance and maintains a low-resistance ground path through the panel interface.

This lockwasher is specified for use with SMB and SMC bulkhead jacks. It fits the standard hex-nut mounting hardware on those connector types. If you are replacing a missing or damaged lockwasher on an existing SMB or SMC bulkhead installation, this is the direct factory part.
