Secure Grounding & Power: Brass Ring Terminal Series (4.2mm to 8.2mm) +U
Achieve high-integrity electrical connections with our Professional Brass Ring Terminal Series. Engineered for permanent and secure terminations, these ring connectors are designed to be bolted onto studs or screws, ensuring a vibration-resistant connection that won't slip or disconnect.
Available in a range of inner diameters—4.2mm, 5.2mm, 6.2mm, and 8.2mm—this series covers everything from small electronic grounding to heavy-duty automotive battery and chassis connections. Crafted from high-purity brass, they offer excellent conductivity and are easy to crimp or solder for a professional-grade finish.
Key Performance Features
-
Precision Sizing: Four distinct sizes to perfectly match standard bolt and stud diameters (M4, M5, M6, and M8).
-
High-Conductivity Brass: Premium alloy construction ensures low electrical resistance and efficient power distribution.
-
Open-Barrel Crimp Design: Features a robust "fold-over" crimp area that provides a high-strength mechanical grip on the wire.
-
Anti-Vibration Security: The closed-ring design ensures the terminal remains attached even in high-movement environments like engines or machinery.
-
Corrosion Resistance: Durable brass material provides a long service life and resists oxidation better than standard steel alternatives.

Top 3 Customer Questions & Concerns �
Which size should I choose for a standard car battery terminal? Most standard battery accessory bolts use an 8.2mm (M8) or 6.2mm (M6) ring. We recommend measuring the stud diameter before purchasing to ensure a snug fit.
� Do these need to be insulated? Since these are "naked" brass, you should apply heat-shrink tubing over the crimp area after installation. This prevents accidental shorts and adds an extra layer of strain relief to the wire.
Can I use a regular pair of pliers to crimp these? While pliers can flatten the tabs, a ratcheting crimp tool for open-barrel terminals is highly recommended. It creates a "B-crimp" that bites into the wire for maximum electrical contact and pull-out strength.
