3/0 AWG,TIN PLATED EYELET, 5/16 STUD

Tin-Plated Heavy-Duty Eyelet Lug — 3/0 AWG, 5/16 Stud

The 3/0 AWG Tin Plated Eyelet 5/16 Stud — SKU: 30516TP is a heavy-duty tin-plated copper eyelet terminal for 3/0 AWG welding cable, battery cable, and large-gauge power wiring, designed for 5/16 stud bolt fixing in motorsport power distribution, battery interconnect, and high-current electrical system builds. The tin plating provides superior corrosion resistance compared to bare copper, extending the service life of the crimp joint in the chemically aggressive environment of a race car engine bay and chassis. 3/0 AWG with a 5/16″ stud provides a high-current termination for distribution busbar connections in complex motorsport power systems.

Heavy-Duty Eyelet Construction for High-Current Motorsport

Large-gauge eyelet terminals are the termination method of choice for battery-positive and battery-negative main cables, alternator output feeds, starter motor power leads, and earthing strap connections in race car and performance vehicle electrical systems. The eyelet design provides a large contact surface area at the stud connection point, minimising contact resistance at the joint and reducing voltage drop across the power circuit — both critical in a high-performance engine where every millivolt of voltage drop at the ignition or fuel injection supply affects reliability and output. The 3/0 AWG barrel of the 30516TP terminal is specifically sized for the conductor cross-section of 3/0 AWG cable, ensuring a full-compression crimp across the entire conductor bundle without under- or over-compression.

5/16 Stud Compatibility — Correct Fixing Point

The 5/16 stud hole diameter matches the most common bolt sizes used for battery terminal posts, busbar studs, and chassis earth points in motorsport electrical systems. A 5/16″ stud is an intermediate size suited to busbar terminal blocks and distribution stud assemblies where an M8 bolt provides the correct clamping torque. Always confirm the stud diameter at the target connection point before ordering.

Tin Plating — Corrosion Resistance at the Joint

Bare copper terminals oxidise at the crimp barrel and eyelet face over time — particularly in motorsport environments where heat cycling, vibration, and exposure to fuel, oil, and moisture accelerate the process. The tin plating on the 30516TP terminal creates a stable, low-oxidation surface at both the crimp interface and the stud contact face, maintaining low contact resistance throughout the service life of the joint. Tin-plated terminals are the professional standard for motorsport power wiring builds where long-term reliability is required.
