The 3Racing TS-BS4516M set contains button head titanium hex sockets intended for reliable fastening in hobby models. These #4-40 x 5/16 screws are light, corrosion resistant and suitable for a variety of hop-up and repair tasks.
Titanium helps lower mass without compromising joint strength, a useful advantage when refining handling or trimming weight. The button head keeps surfaces flush and reduces the chance of snagging on bodyshells or linkage.
Ideal for chassis plates, servo mounts and accessory fittings, these hex sockets cover many routine upgrade points. The popular #4-40 x 5/16 size fits numerous standard RC components for straightforward swapping.
