⚡ At a Glance
- • Durability: Tin-plated copper construction resists corrosion and tolerates high temperatures
- • Best for: DIY repairs, automotive battery connections and small marine applications
- • Not ideal for: Heavy industrial mains connections or cables above 35mm² capacity
Set of ten SC35-10 tinned copper ring terminals with 10.5mm bolt hole, suitable for 35mm² cable. Heavy-duty barrels, marked sizes and a closed design help protect connections from moisture.
Secure electrical contact - thanks to 100% copper core with tin plating
A full-copper core delivers low electrical resistance while the tin-plated outer layer prevents oxidation and maintains contact quality under humid or salty conditions. The plating also helps the lug withstand higher temperatures without degrading.
Consistent current flow and fewer intermittent faults during starter, grounding or battery connections. Expect long service life in automotive or marine environments where corrosion is a common issue.
Quick, repeatable terminations - with flared barrel opening for easy insertion
A flared entry to the barrel allows stripped conductors to be guided in cleanly before crimping; the closed-barrel design seals the conductor once compressed. Compatibility with both crimping and welding/soldering gives mechanical and metallurgical attachment options.
Faster, neater crimps reduce rework and help novices and experienced users achieve reliable connections. For high-vibration applications, an added solder joint gives extra reinforcement.
Easy identification and fitment - thanks to marked model and size
Each lug is stamped with model and size so selection under bench lighting is straightforward, and the SC35-10 designation aligns with the 10.5mm bolt aperture and 35mm² conductor recommendation. A standard bolt hole makes mounting to studs or blocks simple.
Quicker parts selection during repairs and reduced chance of using the wrong lug. The clear marking prevents mistakes when stocking multiple sizes for a workshop or boat.
