Serpent 440181 M3x19.5 Half-Thread Screw 4 pcs for Mini Spyder MT Chassis Mounting  [SER440181]

Half-thread M3x19.5 screw for Serpent Mini Spyder MT

This 4-piece set contains half-threaded M3 screws sized 19.5 mm made for the Serpent Mini Spyder MT. It is a service part used to secure chassis plates, body mounts and other small assemblies where a partial thread length clamps components reliably while the unthreaded shank provides alignment.

Fit and compatibility are limited to the Mini Spyder MT family and related SER440001 chassis parts as specified by Serpent. Use the original mounting points and maintain matching thread engagement when replacing hardware, and keep original washers or spacers in place to preserve ride height and component spacing.

Installation tips: hand-start each screw to avoid cross-threading, tighten progressively and avoid over-torque to protect plastic or aluminium mounting bosses, and consider a low-strength threadlocker for sustained vibration locations. Use an appropriately sized hex driver and check thread condition before reuse.
