Titanium flat head screw for R/C

This HUDY 903320-T titanium flat head screw is an R/C-scale hex-socket fastener supplied in a pack of 4 pcs and sized M3x20 for general hobby use. The flat head form sits flush with plate surfaces and bodywork trims where a countersunk finish is required, while the hex socket drives provide secure engagement for tightening and removal.

As a titanium part, it offers a favourable strength-to-weight ratio and improved corrosion resistance compared with standard steel screw options, making it suitable for exposed chassis locations and lightweight tuning where reducing unsprung or rotating mass is beneficial. The screw is intended for typical R/C assembly and maintenance tasks, including chassis panels, suspension towers, bulkheads and body mount points that accept M3 countersunk hardware.

The role of this screw in tuning is practical: it lets builders maintain flush fittings and precise stack heights without adding excessive weight, and can be swapped in for steel fasteners where rust or weight are concerns. Installation follows standard countersink practice and careful torque control to avoid stripping the M3 thread in aluminum or composite parts.

A compact titanium countersunk screw option for R/C builders seeking a lightweight, corrosion-resistant fastener for M3 countersunk mounting points.
