AM-13CS4020 Arrowmax M4x20 Countersunk Allen Screws

Model enthusiasts can rely on the Arrowmax AM-13CS4020 Allen countersunk M4x20 screws to keep assemblies clean and secure. The countersunk heads reduce protrusion and help preserve the model's lines.

Socket Drive and Strength

The hex socket head allows a tight, controlled fit using an appropriate Allen key, and the steel construction gives dependable holding power across a range of RC parts. This reduces the chance of head damage during tightening.

Where to Use These Screws

Ideal for fastening chassis plates, mounting electronics boxes and attaching body panels, these countersunk screws are handy for any build that benefits from a low-profile fastener.

Can these screws be over-torqued and strip the socket?

Over-torquing any small hex socket can round the recess. Use a correct-size Allen key and steady force; consider a torque-limited driver for repeatable installs to avoid damage.

What size Allen key fits the M4 socket?

A standard M4 hex socket typically uses a 3 mm or 2.5 mm Allen key depending on the head design. Check the driver fit before applying full torque to avoid rounding the socket.
