Hobbyists servicing their models will appreciate the Serpent SER110177 Screw Allen Roundhead M4x12 10 pack as a practical set of spares. The hex drive gives good torque control to tighten components while minimising cam-out during routine work.
The M4x12 dimension is a frequent choice across many kits and conversions, lending itself well to chassis, mountings and accessory attachments. These screws suit general repairs and small upgrades where a reliable hold is needed.
Made to withstand regular handling, the roundhead profile sits neatly against panels and brackets to reduce snagging and keep a tidy appearance on running models.
