Non-Insulated 6 AWG Ring Connector 5/16 in - 100 Pack

Our review of the Sherco-Auto Non-Insulated 6 AWG Ring Connector 5/16 in 100 pack finds it best for technicians and hobbyists who need reliable, corrosion-resistant terminals in quantity. The single biggest reason to buy is the combination of pure copper construction and electro tin plating that delivers strong conductivity and long-term resistance to corrosion, while clear size markings and V groove serrations make consistent crimping straightforward. For anyone wiring automotive or marine systems who values repeatable mechanical and electrical performance, this connector set is a practical choice.

Key Features

• Pure copper construction: Alloy 110 base metal ensures excellent conductivity for stable electrical connections in demanding applications.
• Electro tin plating: Provides exceptional corrosion resistance so terminals hold up well in automotive and marine environments.
• V groove serrations: Serrated interiors increase contact area and tensile strength after crimping for secure mechanical retention.
• Clear size markings: Terminals are marked with size to speed identification and reduce wiring errors on the bench or in the field.
• 100-piece pack: A bulk quantity that suits multiple repairs or installations without repeated orders or part mixing.
• Mil-spec construction: Built to MIL-T-10727C Type 1 and ASTM B 545 B standards for consistent manufacturing quality.

Who It's For

This pack is aimed at professional mechanics, marine electricians, and serious DIYers who regularly terminate 6 AWG cable for batteries, starters, grounding, or power distribution and need a reliable, corrosion-resistant terminal. The 100-piece count and non-insulated design make it ideal for repeated shop use where heat shrink or other insulation will be applied after crimping.

It is not the best choice for casual users who prefer insulated terminals for immediate finger-safe handling or very small one-off repairs where buying bulk is unnecessary. Customers who require an insulated, pre-insulated flange or different stud sizes should look elsewhere.

Pros & Cons

Pros

• Pure copper alloy and tin plating combine for strong conductivity and real corrosion resistance.
• V groove serrations promote consistent, high-strength crimps and better tensile retention.
• Hundred-pack quantity reduces reordering and supports multiple installations or projects.
• Clear size markings and mil-spec build improve confidence when matching terminals to applications.

Cons

• Non-insulated design requires additional insulation steps after crimping for safety in exposed installations.
• Only available for 5/16 in studs and 6 AWG wire size, so it is not universal for other gauges or stud diameters.
