High Temp 6 AWG Ring Connector 100 Pack - Durable Crimp Terminals

In this review the Sherco-Auto 100 Pack High Temp Non-Insulated Ring Connector is assessed for installers who need reliable, compact terminals for heavy copper wiring. The bottom line: this kit is aimed at automotive, marine and industrial technicians who need a large quantity of 6 AWG ring terminals that tolerate extreme heat and maintain strong crimps. The reviewer found the pure copper construction with V-groove serrations and high temperature rating to be the single biggest reason to buy, because it reduces rework under demanding thermal or cramped-space conditions.

Key Features

• High temperature rating: Rated to 482 C / 900 F so these terminals are suited to applications where heat resistance is critical.
• Wire and stud compatibility: Sized for 6 AWG wire with a 1/4 in stud, providing a direct fit for common heavy gauge grounding and power runs.
• Construction: Pure copper with V-groove serrations ensures consistent crimp retention and good conductivity for low-resistance connections.
• Low profile: The.565 in length and.14 in diameter design keeps the ring terminal compact for limited-space installations.
• Quantity and origin: Pack of 100 made in the USA offers bulk value and traceable manufacturing for professional use.
• Electrical rating: Rated at 600V, making these suitable for many automotive, marine and industrial electrical tasks.

Who It's For

These ring connectors are best for professional mechanics, marine electricians and industrial maintenance crews who regularly terminate 6 AWG copper wire where elevated temperatures or tight spaces are a concern. The large 100-piece pack makes them practical for fleets, shops or project stockrooms that need consistent, high-quality terminals.

Those who should look elsewhere include users who need insulated or solder-type terminals, or anyone wiring aluminum conductors, as these are specified for copper wire only. If you need a different stud size or thinner gauge terminals, choose a product matched to those specific dimensions.

Pros & Cons

Pros

• High temperature tolerance up to 900 F supports use near heat sources without degradation.
• Pure copper body with V-groove serrations gives reliable crimps and good electrical conductivity.
• Made in the USA and supplied in a 100-piece bulk pack, offering professional value and consistency.

Cons

• Non-insulated design means additional protection may be needed in exposed or vibration-prone environments.
• Specified for copper only, so not appropriate for aluminum wiring without proper treatment.

Frequently Asked Questions

Are these terminals insulated?
They are non-insulated; additional insulation or heat-shrink should be applied if required for the installation.

Can these be used on aluminum wire?
No, they are specified for use with copper wire only and should not be used on aluminum without proper conversion measures.

What crimp method is recommended?
Use a proper ratchet crimper sized for 6 AWG to form consistent crimps with the V-groove serrations for best retention and conductivity.
