Screw M5 x 16 mm, Leybold, Trivac, Part# 400066 – vacstellar

This M5 x 16 mm screw is an essential fastener for assembling and maintaining your Leybold Trivac vacuum pump. Using the correct factory screw ensures a secure, reliable fit for panels, covers, and internal components. 

A pump has many vibrations and temperature changes. Using the right screw, made to the correct specification, means everything stays tightly fastened.

Using random screws from a hardware store can be risky. They might not have the exact right strength or fit. This can lead to parts coming loose, which might cause leaks or other problems.

This is the official Leybold part. It’s the exact screw specified for your Trivac pump. When you’re doing maintenance or a repair, using this screw gives you confidence. You know it will fit perfectly and do its job reliably.
