Low-Profile M3x20 Screws from Arrowmax AM-13CS3020

For model makers who value tidy assembly, the Arrowmax AM-13CS3020 Screw Allen Countersunk M3x20 (10 pieces) is a practical choice. These steel countersunk screws are intended to blend into body panels and structural parts while keeping connections secure.

Why Countersunk Fasteners Matter

Countersunk heads allow the screw to sit flush, which is useful where clearance is tight or you want a smooth surface on shell panels. That feature reduces interference and gives a cleaner finish.

Typical Uses for M3x20 Hardware

M3x20 is a versatile length for fixing chassis items, mounting electronics brackets, and fastening panels. The hex socket makes installation quick and helps avoid damage during repeated servicing.

Are these suitable for aluminium chassis plates?

They work fine with aluminium parts that accept M3 threads; use the correct thread engagement and avoid overtightening to protect tapped holes.

Should I use threadlocker with these screws?

For high-vibration areas, a mild threadlocker can help retain the screws. For removable panels, choose a removable-grade threadlocker or none at all.

Can these be reused after removal?

Yes, they can usually be reused several times if the socket and threads remain in good condition. Inspect for wear before reinstalling.

Do they come in different finishes?

This pack is steel finished for general use. For specialised finishes, check product lines that list coatings or stainless options.
