10mm (3/8") Positive Insulated Power Junction Stud – Red

Heavy-Duty High-Current DC Terminal Post for Marine & 4WD Systems

Streamline your high-amp 12V and 24V power distribution with the 10mm (3/8") Red Insulated Power Junction Stud. Designed for heavy-duty automotive, dual-battery, 4WD, and marine installations, this robust terminal post provides a secure, central connection point for joining large-gauge battery cables, connecting auxiliary feeds, or extending main power leads.

Built with a high-tensile stainless steel stud and a glass-filled nylon insulated base, it offers exceptional mechanical strength, heat resistance, and chemical durability. The vibrant red color ensures instant positive polarity identification, while surface-mount screw holes allow for clean, rigid mounting against firewalls, battery boxes, or canopy walls.

Key Features

• 10mm (3/8") Stainless Steel Stud: Accommodates large heavy-duty cable lug sizes (#3/8 / M10 ring terminals) for high-amp battery connections.

• Red Polarity Identification: Clear color-coded base prevents wiring errors and allows for rapid visual identification of positive power feeds.

• Heavy-Duty Construction: Glass-fiber reinforced nylon base provides superior dielectric strength, flame retardancy, and resistance to oil and fuel.

• Surface-Mount Flexibility: Pre-drilled mounting holes allow for easy, secure installation on any flat panel, bulkheads, or custom battery boxes.

• Corrosion-Resistant Hardware: Stainless steel stud, nuts, and washers defend against rust, oxidation, and salt-air marine environments.
