The Serpent 440170 kit includes ten M2x6 countersunk self-tapping screws intended for RC-scale use on the Mini Spyder Monster Truck chassis. These items function as direct replacement fasteners when original screws are lost or damaged during service or adjustments on the Mini Spyder MT RTR.
Fitment focuses on the Mini Spyder MT family (SER440001) and mounting points that require M2x6 CS self-tapping hardware. Install these into locations that originally call for countersunk M2 fasteners to restore secure joins between chassis plates, body mounts, suspension brackets, and accessory points.
Installation guidance: select the correct Phillips or compatible driver to minimise cam-out, tighten with moderate torque to avoid stripping the formed threads, and check alignment before insertion. For parts that see repeated removal, alternate with a replacement insert or maintain the original hole profile to protect thread life.
Tuning note: although small, proper fasteners contribute to consistent chassis preload and geometry. Properly seated countersunk screws help keep body mounts and bracket faces flush, aiding repeatable ride height after maintenance.
