6 AWG,TIN PLATED EYELET, 3/8 STUD

HD Tin-Plated Eyelet — 6 AWG / 3/8″

The 6 AWG Tin Plated Eyelet 3/8 Stud — SKU: 638TP is a heavy-duty tin-plated copper eyelet terminal for 6 AWG large-gauge cable, providing a reliable, corrosion-resistant crimp termination for motorsport battery wiring, alternator output feeds, earth straps, and high-current power distribution in race car and performance vehicle electrical systems. The tin plating over the copper barrel and eyelet ring suppresses oxidation at both the crimp interface and stud contact face, ensuring stable, low-resistance connections throughout the terminal’s service life.

6 AWG — Gauge Selection

6 AWG at a 3/8″ stud is the combination for terminating a substantial wire gauge directly at a main battery post, alternator B+ terminal, or primary earth stud. The 638TP crimp barrel is sized precisely for 6 AWG conductor cross-section — ensuring full barrel fill during crimping for maximum mechanical retention and minimum contact resistance.

3/8″ Stud — Fixing Size

The 3/8″ stud is used for main battery terminal posts, alternator output B+ stud bolts, and heavy chassis earth anchor points requiring high clamping torque. Verify the stud or bolt diameter at the target connection point before ordering to ensure correct fit and adequate contact surface area at the power circuit join.

Tin Plating — Joint Integrity

Bare copper terminals oxidise when exposed to heat cycling, moisture, and the chemically active atmosphere of a race engine bay. Oxidation increases resistance, generates heat under load, and accelerates joint degradation. The tin plating on the 638TP resists oxidation far longer than bare copper, maintaining joint quality across a full racing season and multiple years of competitive use.
