Precision M3x20 Countersunk Screws from Arrowmax AM-13CS3020

Good model assembly depends on correct hardware. The Arrowmax AM-13CS3020 Screw Allen Countersunk M3x20 (10 pieces) supplies a straightforward fix for paneling and chassis attachments. These steel screws are intended to offer a neat, low-profile connection across a range of hobby parts.

Why Choose Countersunk Heads

Countersunk screws recess into the mounting surface so the head sits level with the part. That helps avoid interference with moving parts and keeps the exterior tidy on visible panels.

Common Uses Around the Model

The M3x20 size is commonly used for securing mounts, trimming panels and general structural attachments. The hex drive allows for controlled tightening and easier removal during upgrades.

Will these work with tapped aluminium parts?

They are suitable for tapped aluminium where M3x20 is specified; ensure correct thread engagement and avoid over-torquing to protect the threads.

Are these compatible with standard body posts?

If your body posts accept M3 screws and the 20 mm length is appropriate, these will work. Check clearance and thread type before fitting.

Do I need a special driver for installation?

A standard hex driver sized to the screw head is all that is needed. Using the right tool reduces the chance of socket damage.

Can these be used outdoors or in damp conditions?

These are steel screws and may benefit from protective coatings for prolonged exposure to moisture. For damp environments, consider corrosion-resistant alternatives if required.

How should I store spare screws?

Keep them in a dry, labelled container to avoid mix-ups with other sizes and to reduce corrosion risk. Small parts organisers work well for hobbyists.
