Yokomo ZC-TP3510 M 3.5x10 Tapping Screws — Hex Socket Self-Tapping for RC Models  [ZC-TP3510]

Tapping screws for RC chassis

This is an RC-scale hex socket tapping screw specified as M 3.5x10, intended for general replacement and maintenance of model components where a self-tapping fastener is required. The part is useful when original fasteners are stripped, lost, or when a stronger thread engagement is needed in plastics and thin alloy parts commonly found in model assemblies.

Installation is straightforward: start by aligning the parts, drive the screw with an appropriate hex driver, and avoid overtightening to prevent thread damage in softer materials. Because these are self-tapping screws, they form their own mating thread when driven into compatible substrates, so pre-drilling is usually unnecessary on typical RC plastic parts but may be recommended for very hard materials.

In tuning and maintenance work, these screws serve a practical role: they secure chassis plates, electronics brackets, servo mounts, and body posts where a compact, hex-drive fastening is preferred. Treat the component as an RC accessory and select torque carefully to balance hold and part longevity.
