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

Half-thread M3x19.5 fastener for Mini Spyder MT chassis

This listing is for four half-threaded M3 screws, each 19.5 mm long, specified for use on the Serpent Mini Spyder MT. They function as replacement fasteners to secure chassis plates, body mounts and other minor assemblies where a short threaded section is required for reliable clamping while a smooth shank aligns parts.

Intended compatibility covers the Mini Spyder MT series and related SER440001 chassis parts as identified by Serpent. When fitting replacements, use the original mounting points, check thread engagement and keep any washers or spacers in place to maintain the original spacing and ride height.

Fitment advice: begin screws by hand to avoid cross-threading, tighten evenly and do not over-torque plastic or aluminium bosses. A low-strength threadlocker is suitable for vibration-prone areas; always use the correct hex driver and inspect threads before reuse.
