Straight 1/0 Gauge Battery Terminals

These copper terminals accept 1/0 gauge cable and connect with a 5/16 inch stud bolt. The black finish identifies polarity at a glance. Each pack contains five pieces for multi-battery banks or spares. They meet SAE J163 dimensional standards.

Replacing Corroded or Undersized Clamps

Swap out worn lead clamps when voltage drop appears or when upgrading to thicker 1/0 cable. The jump is worth it if the existing terminals cannot accommodate the larger conductor or show heat damage. Not for systems that require smaller gauge connections.

Simple Bolt-On Installation

Strip the cable, insert it into the barrel, and tighten the included 5/16 bolt to secure the connection. The copper barrel crushes evenly when torqued correctly. Over-tightening can split the barrel, while under-tightening leaves a high-resistance joint.
