SKU CH-0Z7X-29A5Y

A tinned brass battery terminal with a 5/16" stud for negative connections resists corrosion and seals out moisture

  • Engine BrandAncor
  • Marine-grade tinned brass resists salt and moisture corrosion
  • 100% tin plating prevents oxidation on the terminal surface
  • Seamless barrel design delivers maximum crimp strength
  • Closed-end construction seals out moisture to keep cables dry
  • 5/16" stud fits standard negative battery posts

Marine Grade Terminal

This Ancor battery terminal uses a 5/16 inch stud and is marked for negative polarity. It is built for marine electrical systems where reliable connections are critical. The tinned brass construction suits boats and other wet environments. Buyers who need a positive terminal or a different stud size must look elsewhere.

Corrosion Resistance Limits

The 100 percent tin plating resists salt and moisture corrosion that destroys standard terminals. The closed end design seals out water so cables stay dry and corrosion free. The seamless barrel provides maximum strength when crimped properly. Installations exposed to constant spray or immersion beyond typical marine conditions may still degrade over time.

Heavy Duty Build

The terminal is manufactured from heavy duty annealed tinned brass for maximum current flow. The seamless barrel design allows for a strong crimp that resists vibration. The closed end keeps moisture out of the cable connection day to day. A Proposition 65 warning applies due to di(2-ethylhexyl)phthalate content.

Questions about this item

Which Ancor battery terminal should I choose for a negative post with a 5/16" stud?

This terminal is built for negative posts and fits a 5/16" stud; its tinned brass construction resists corrosion and the closed end keeps moisture out.

What does the 100% tin plating actually do once the terminal is installed?

The full tin coating on the brass lug blocks salt and moisture from reaching the copper strands, so the connection stays conductive in marine environments.

How does the 5/16" stud size limit the cables or lugs I can use with this terminal?

The stud accepts lugs drilled for a 5/16" bolt, so you must match that hole size; the seamless barrel then crimps tightly around the cable for maximum strength.
