The Yokomo ZC-BH320A M3X20 Button Head Socket Screws are a straightforward option for routine RC repairs and small upgrades. Made to ISO dimensions, they fit many hobby parts and accessories.
With a 3mm thread and a 20mm shaft (measurement excludes the head), these screws suit chassis plates, servo mounts and trim brackets where a low head is preferred. The button head keeps panels flush.
Use a 2mm hex key to tighten these screws securely while avoiding over-torque. Packs include eight screws, handy for several maintenance jobs or spares kits.
