PowerVector 8mm Bulkhead Terminal - Battery Cable Passthrough

The PowerVector 8mm Bulkhead Terminal delivers clean, secure battery cable routing through firewalls and panels. Sized for primary battery feeds and high-current accessories in motorsports applications where vibration resistance and professional installation matter.

Unlike standard two-bolt pass-through studs, the PowerVector features a four-bolt mounting pattern with a flat sealable surface—giving you a weathertight connection that stays tight through endurance races, track days, and spirited driving. Embedded lock nuts allow complete installation from one side of the panel, eliminating the frustration of reaching behind firewalls or working in tight engine bays.

Every PowerVector Bulkhead Stud ships fully assembled with all 304 stainless steel hardware included. Drill your hole, bolt it down, connect your cables.

Available in Black, Red, or Orange glass-reinforced nylon. Assembled in the USA.
