Non-Insulated 2 AWG Ring Connector 1/2 in Stud - 1000 Pack

In this review the Non-Insulated 2 AWG Gauge Ring Connector 1/2 in Stud from Sherco-Auto is evaluated for installers and fleet maintenance teams who need bulk, reliable uninsulated terminals. The bottom line: this 1000 pack delivers consistent, US-made copper terminals with strong corrosion resistance and serrated contact surfaces that make repeated crimping work predictable. For anyone wiring heavy battery cables or grounding large conductors, the terminal construction and mil-spec backing make it an easy choice for long runs and repeated installations.

Key Features

• Pack size: A 1000 piece package removes the need for frequent reordering and suits high-volume shops.
• Material: Constructed from pure copper Alloy 110 with electro tin plating to resist corrosion in marine and automotive environments.
• Crimp performance: V groove serrations provide maximum contact area and tensile strength after crimping for secure joints.
• Identification: Terminals and connectors are clearly marked with size to speed selection during installation.
• Standards: Manufactured to Mil Specs MIL-T-10727C Type 1 and ASTM B 545 B for consistent quality across the lot.
• Stud compatibility: 1/2 in stud size that fits common battery and chassis terminals used in heavy gauge wiring.

Who It's For

The product is aimed at professional electricians, automotive technicians, marine electricians, and fleet mechanics who regularly terminate 2 AWG gauge cable and need a consistent, bulk supply. The 1000 count and mil-spec construction are most valuable in workshop or production settings rather than for occasional DIYers.

Those doing one-off home projects or needing insulated terminals for vibration-sensitive, exposed connections should look elsewhere; this is an uninsulated terminal intended for protected or bolted-down applications where insulation is not required.

Pros & Cons

Pros

• Made in the USA using pure copper Alloy 110 with electro tin plating for reliable corrosion resistance.
• V groove serrations improve mechanical and electrical contact after crimping.
• Large 1000 pack reduces downtime for shops and service fleets.
• Clearly marked sizes speed identification on the bench or in a parts bin.

Cons

• Uninsulated design means users must provide additional protection or use in protected assemblies to prevent shorting.
• Bulk quantity may be excessive for occasional DIY installers who need only a few terminals.
