SUPCO T1004C Insulated Male Slip-On Terminals

This pack contains 100 insulated male slip-on terminals designed for 12-10 wire gauge connections. Each terminal accepts a .250 tab size, equivalent to 1/4 inch, ensuring a secure fit for standard automotive and electrical applications. The vinyl insulation provides protection against accidental shorts and environmental exposure. Electricians and automotive technicians will find the bulk quantity convenient for workshop stock or large wiring jobs.

Installation ease and common pitfalls

The slip-on design allows for quick installation without soldering, simply crimp the terminal onto the stripped wire and push onto the mating tab. A proper crimp tool sized for 12-10 gauge wire is essential to achieve a reliable mechanical and electrical connection. Common issues include using pliers instead of a ratcheting crimper, which can leave loose strands, and failing to fully seat the terminal onto the tab, leading to intermittent contact or overheating.

Pre-order checklist for your setup

Verify that your wire gauge falls strictly within the 12-10 range, as smaller or larger conductors will not crimp correctly in these terminals. Confirm the mating tabs on your components measure .250 inches (1/4 inch) to match the terminal receptacle. Ensure you have a quality crimping tool with the appropriate die nests for insulated terminals of this wire size before starting the job.

Questions about this item

How can I confirm the terminals are correctly crimped to 12-10 gauge wire?

After crimping, tug the wire firmly; a secure joint will not pull free. The insulation should sit flush against the barrel with no exposed conductor visible.

What comes in the pack and what extra items are needed for installation?

The pack contains 100 insulated male slip-on terminals with a .250 tab size. You must supply 12-10 AWG wire and a suitable crimping tool separately.

Which tab size should I select for a standard 1/4-inch female receptacle?

The terminals feature a .250 tab, which equals 1/4 inch, so this single version matches standard female receptacles directly.
