  • Tin-plated finish resists corrosion effectively
  • One-hole ring tongue fits 5/16 in studs
  • Short barrel design suits tight spaces
  • UL Listed and CSA Certified for safety

One-Hole Lug for 2 AWG Copper

The 3M MC2-516RX is a straight-barrel compression connector built for 2 AWG copper cable. Each lug carries a brown colour code and die code 10 for quick identification during installation. The pack supplies 100 pieces suited to high-volume electrical work in automotive and industrial settings.

Replaces Crimp or Solder Joints

Compression termination removes the variability of hand-crimped or soldered connections on heavy-gauge wire. The upgrade is worth it when vibration, thermal cycling or corrosion risk demand a gas-tight, mechanically locked joint that meets CSA and UL requirements.

100-Piece Pack for Production Runs

The tin-plated copper barrel handles 2 AWG conductors with a 5/16 in stud hole and 1.62 in overall length. The 0.65 in width fits standard bus-bar spacing, while the short barrel conserves space in tight enclosures. No peep hole means the barrel is fully closed for maximum mechanical strength.

Questions about this item

What stud size does the 5/16 in ring tongue on the MC2-516RX lug fit?

The ring tongue is drilled for a 5/16 in stud, so it bolts directly onto terminals or bus bars with that diameter.

Which crimp die code should be used to install these copper lugs correctly?

Use die code 10 with a compatible compression tool; the brown color band on the barrel confirms the correct die setting.

Will the tin plating on these copper lugs need re-coating after years of service?

The factory tin plate protects the copper from oxidation; under normal conditions it lasts the life of the connection without re-application.
