Washers spread load, protect surfaces, and help keep threaded fasteners from working loose, and this category gathers steel SAE washers in the small sizes model builders use most. Plated steel resists corrosion and gives a clean finished look on visible hardware.
Flat and Fender Washers
Flat plated steel washers in #2, #3, and #4 sizes seat under a screw head or nut to distribute clamping force. Fender washers in #2 and #4 add a wider outside diameter, which is useful when a hole is oversized or the material is soft and needs more bearing area.
Lock Washers
Split lock washers in #2 and #4 provide spring tension against a nut or screw head to help resist loosening from vibration, a common concern on running engines and airframes. Keeping a small assortment on hand means the right washer is ready whenever an assembly calls for one.
