The 3Racing TS-BS4516M kit gives hobbyists precision titanium fasteners for common hop-up and repair tasks. Machined from aircraft-grade titanium, these #4-40 x 5/16 screws balance low mass with corrosion resistance so your build stays reliable and light.
Titanium delivers an excellent strength-to-weight ratio, helping reduce overall mass without sacrificing clamp force. The button head profile sits low for a tidy appearance and lowers the chance of snagging on bodywork or components.
These hex sockets suit a broad range of RC uses, from chassis mounting to upgrade hardware. The #4-40 x 5/16 size is a common choice for hop-up parts and general maintenance, providing dependable threading and fitment.
