Frequently Asked Questions

Q: What sizes of copper hex socket screws are included in this listing?

A: This listing covers M2, M3, M4, M5, M6, and M8 round head hex socket machine screws. Please select your required size at the time of purchase. Each pack contains 50–99 pieces depending on the size selected.

Q: Why choose red copper (T2) screws over standard steel screws for electrical applications?

A: T2 red copper offers significantly higher electrical and thermal conductivity compared to steel or zinc-plated fasteners. This makes copper machine screws the preferred choice for grounding connections, circuit board assemblies, and any application where low electrical resistance and efficient heat transfer are critical.

Q: What tool is needed to drive these hex socket screws?

A: These screws use a hex socket (Allen key) drive. You will need the appropriately sized hex/Allen key or hex bit driver corresponding to your screw size (e.g., M2 uses a 1.5mm hex key, M3 uses a 2mm hex key, etc.).

Q: Are these screws suitable for outdoor or humid environments?

A: Yes. Copper naturally resists corrosion and oxidation, making these screws well-suited for environments where moisture or mild chemical exposure may be present. They are an excellent alternative to stainless steel where electrical conductivity is also required.
