VERSAKRIMP 4 GA RING TERMINAL 5/16 BRAZED SEAM

Molex Versakrimp 4 GA Ring Terminal — 5/16 Brazed Seam Lug for Motorsport Primary Wiring

The Molex Versakrimp 4 GA Ring Terminal with 5/16 hole (19193-0267) is a heavy-duty brazed-seam crimp lug for motorsport and high-performance vehicle primary circuit terminations. At 21.1 mm² conductor cross-section with a continuous current capacity of approximately 95–120 amps, this terminal is suited to main battery positive and negative connections, starter motor cable terminations, and primary distribution bus lugs. The brazed seam barrel construction provides a stronger, more reliable crimp joint than a simple rolled-seam barrel, maintaining electrical integrity under the vibration and thermal cycling of a race car environment.

Brazed Seam Construction

A brazed seam barrel is formed from copper that is rolled into a cylinder and then joined with a brazed filler material that closes the seam completely, creating a fully continuous cylindrical conductor. Under heavy crimp forming pressure at large wire gauges, a brazed seam barrel resists splitting — a failure mode seen with lower-quality terminals when crimping heavy conductors. The result is a tighter, more consistent crimp that reduces the risk of high-resistance joints in primary power circuits.

5/16 Hole Size — M8 equivalent

5/16-inch (M8) stud mount — suits M8 terminal studs on battery posts, MEGA fuse holders, and primary distribution blocks. Selecting the correct hole size for the target stud is essential: an undersized hole cannot be installed, while an oversized hole leaves the terminal loose on the stud even when the nut is tight, creating micro-movement under vibration that accelerates contact surface oxidation.

4 GA — Typical Applications

This ring terminal is suited to main battery positive and negative connections, starter motor cable terminations, and primary distribution bus lugs. At this cable gauge, the terminal is part of the primary power circuit — the highest-current section of the vehicle’s electrical system — making a correctly specified and installed terminal critically important for both performance and safety.
