Arrowmax AM-13CS4020 M4x20 Countersunk Allen Screws

Hobby builders who want dependable hardware will appreciate the Arrowmax AM-13CS4020 Allen countersunk M4x20 screws. These fasteners are made to sit flush in panels and plates, helping keep your model neat while maintaining structural strength.

Built for Precision and Fit

The M4x20 screws use a hex socket head for secure driving and removal, and they are manufactured from robust steel to tolerate routine maintenance. The countersunk profile lets the screw head disappear into the material for a clean finish.

Common RC Uses

These screws are suitable for securing chassis plates, mounting brackets and body fixings where a flush surface is needed. Their design helps avoid snagging and keeps bodywork tight against the frame.

Will these M4x20 countersunk screws work on aluminium and plastic parts?

Yes, the Arrowmax AM-13CS4020 M4x20 screws are suitable for both aluminium and plastic mounting points, provided the hole is countersunk to accept the head. Use the correct pilot hole and thread engagement for the material.

What driver should I use to avoid stripping the head?

Use a quality M4 hex driver or Allen key that matches the socket size and apply steady torque. A proper driver reduces cam-out and keeps the socket from rounding off.
