Lightweight m2 aluminum lock nuts with nylon insert. Anodized finish. 10 pack. Perfect for shock mounting screws on the Losi Mini-T 2.0, Mini-B, Mini Drag, and any other vehicle that might use an M2 locknut.

Note these have a larger outer diameter hex than stock. These require a somewhat unconventional 4.5mm hex driver. Our thumb nut driver (available separately) is recommended.
