For hobbyists who value clean builds, the Arrowmax AM-020042 Aluminium M4 Countersink Washers are a practical choice. Constructed from aluminium, these washers help hold components securely without adding unnecessary weight.
The countersunk M4 form allows screw heads to sit level with panels, reducing the chance of interference with moving parts. The orange hue improves visibility when fitting or checking hardware.
These washers fit many kinds of RC projects, from foam gliders to scale cars, and are useful for both new builds and maintenance tasks where a secure, low-profile fastener is needed.
