Why Choose SC6-25 Ring Terminals?
Ring-type crimp terminals are the industry standard for secure, permanent wire-to-stud connections. The ring design prevents accidental disconnection, making them the preferred choice for grounding points, battery terminals, and high-reliability electrical joints. The SC6-25 size is especially popular in solar energy setups, marine wiring, and automotive electrical work.

Frequently Asked Questions
Q: What wire size is the SC6-25 ring terminal compatible with?
A: The SC6-25 ring-type crimp terminal is designed for cables with a cross-sectional area of 6 mm². The "25" in the model name refers to the stud hole diameter of 25 mm, making it suitable for larger bolt or screw connections commonly found in automotive, solar, and industrial wiring applications.
Q: How do I install a SC6-25 ring-type crimp terminal connector?
A: Installation is straightforward: strip approximately 10–12 mm of insulation from the cable end, insert the bare wire into the copper barrel of the ring terminal, then use a crimping tool to compress the barrel firmly onto the wire. The ring end then slides over a bolt or stud and is secured with a nut. No soldering is required, making it a fast and reliable connection method.
Q: What applications are SC6-25 ring terminals used for?
A: SC6-25 ring-type crimp terminals are widely used in automotive wiring (battery and ground connections), marine electrical systems, solar panel and inverter installations, home electrical distribution boards, and industrial control panels — anywhere a secure, low-resistance wire-to-stud connection is needed at low-voltage levels (below 50V AC or 75V DC).
Q: Are these connectors made of pure copper?
A: Yes. The SC6-25 crimp terminals are made from pure copper, which provides superior electrical conductivity compared to aluminium or copper-clad alternatives. Pure copper terminals also offer better corrosion resistance and mechanical durability over the long term.
