Precision Fixing with XRAY SFH M4x20

For builders who care about neat assembly, the XRAY Hex Screw SFH M4x20 kit delivers ten precision flat head screws. The hex drive lets you tighten and remove fasteners quickly while keeping parts flush and tidy.

Where These Screws Work Best

The M4x20 length and flat head shape make these screws ideal for panel mounting, servo brackets and other spots where a smooth surface is preferred. They balance strength and a low profile for clean installs.

Model Compatibility Notes

These screws are compatible with many RC platforms that accept M4 hardware. They are suitable for hobby builders at all levels and are useful for routine maintenance or upgrades.
Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Can I use these on aluminium parts?

Yes, they can fasten aluminium components provided the thread depth and hole diameter match the M4 specification.

Do these screws need threadlocker?

Threadlocker is optional depending on vibration levels; for high vibration applications a light threadlocker can help prevent loosening.

What is the head type on these screws?

They are flat head (countersunk) screws with an internal hex drive for a flush finish when mounted.

Will these work with standard servo mounts?

They are commonly used for servo mounts if the mount accepts M4 fasteners; check depth to avoid head interference.
