Screw, M5 X 40 mm, Leybold, Trivac, Part# 400062 – vacstellar

This M5 x 40 mm screw is an  Leybold replacement part. While it may look like a standard piece of hardware, it is engineered for a specific job. It provides a secure and reliable fastening point on your Leybold Trivac pump.

Using the correct factory screw is important. It guarantees the exact thread pitch, length, and head style needed. This ensures a perfect fit that won’t strip threads or cause misalignment. A proper fit keeps your pump’s casing and internal components securely fastened.

This part (Part# 400062, also known as L0308) is compatible with several Trivac E-Series models. These include the D2.5E, D5E, D10E, and D16E pumps.

Always use the right part for the job. During reassembly after maintenance, replacing old or worn screws with these parts helps ensure your pump operates safely and reliably for years to come.
