This M4WD-26 socket button screw is supplied as a replacement part compatible with Tamiya Mini 4WD kits. The writeup stresses that thread size and the 30 mm length are the principal details builders need to match when sourcing a spare.
Model builders will use this fastener to secure posts, braces and other chassis fittings where an M2 x 30 is specified. Check that the head profile and thread engagement suit the intended mounting point to avoid affecting panel seating or roller clearance.
No assumptions are made about alloy or finish. For workshop best practice, fit with the correct hex driver and apply moderate torque. If a removable locking product is preferred, pick one suitable for small fasteners and routine servicing. Keep screws organised by type for accurate reassembly.
