FAQs
What wire sizes are these compatible with?
These terminals are specifically designed for 12 to 10 AWG wire.

Each pack contains 100 individual bullet terminals.
What is the diameter of these bullet terminals?
They feature a standard 5mm diameter.
Are these crimp-only or solder-type terminals?
These are designed to be crimped onto the wire using a standard electrical crimping tool.
What does the yellow color indicate?
In the electrical industry, yellow insulation indicates that the terminal is rated for 12-10 AWG wire.
Troubleshooting
Terminal pulls off wire after crimping
Ensure the crimp tool is set to the correct gauge (yellow) and verify that the wire was stripped to the proper length for a secure mechanical lock.
Difficulty inserting wire into terminal
Check that the wire strands are neatly twisted and not frayed. Ensure the wire gauge is not larger than 10 AWG.

Setup, Compatibility & Care
To set up these terminals, select a crimping tool rated for the 12-10 AWG (yellow) range.
- Strip approximately 6mm of insulation from your wire.
- Insert the conductor into the terminal barrel.
- Position the crimping tool dies over the insulated section and the metal barrel.
- Apply firm, steady pressure until the tool releases.
Compatibility is limited to 5mm bullet connector housings. For care, keep the pack in a cool, dry place to prevent oxidation of the metal terminals before use. If installed in high-moisture environments, consider using heat-shrink tubing over the connection for added protection.
