Koswork 3x5mm Button Head Hex Hardened Steel RC Screw - KOSBS305

The Koswork KOSBS305 is a set of 3x5mm button head hex hardened steel screws supplied in a convenient storage container, designed for use in RC cars and competition-grade RC builds. Button head hex screws are a common fastener choice across chassis plates, body mounts, and electronic component brackets, where a low-profile head is needed alongside a secure hex drive. The hardened steel construction gives these screws the strength to handle the stresses of RC use without stripping or deforming under torque.
