Pacer Performance TAE4-12R-10 Tinned Copper Lug 4 AWG 1/2" Stud 10 Pack

The Pacer Performance TAE4-12R-10 is a professional-grade tinned copper lug designed for high-performance electrical connections in automotive, marine, and industrial applications. This 10-pack of 4 AWG lugs features a 1/2" stud size, making them ideal for battery cables, heavy-duty wiring harnesses, and power distribution systems.

Superior Construction:

Each lug is manufactured from 100% pure electrolytic tough pitch (E.T.P.) copper for maximum conductivity. The copper undergoes full annealing to prevent cracking during crimping and throughout its service life. A complete tin plating protects against corrosion and ensures long-term reliability in harsh environments. The seamless construction eliminates exposed seams that could compromise electrical performance.

Key Features:

• 4 AWG wire capacity with 1/2" stud diameter
• Tin-plated copper construction prevents corrosion
• Seamless design provides 100% conductivity with no failure points
• Fully annealed copper resists cracking during installation
• Cold-weld crimp connection creates permanent, solid bond
• Compact dimensions: 1.625" length, 0.766" width, 0.469" clearance

Certifications and Compliance:

• E.T.P. (Electrolytic Tough Pitch) CDA-110 copper
• ASTM-B-152 certified copper material
• RoHS compliant for environmental safety
• CSA approved for Canadian standards
• UL approved for electrical safety

These general-purpose electrical terminals are commonly used for battery cable terminations, starter motor connections, alternator wiring, inverter installations, and other high-current applications. The tin plating makes them particularly suitable for marine environments where corrosion resistance is critical. Package includes ten lugs.
