Sta-Kon A71FPF PLAIN FINISH TERM

The A71FPF accepts 22 to 16 AWG stranded conductor. That covers the typical control, signal, and low-voltage wiring found in thermostat runs, panel interconnects, and access control wiring. For 14 AWG and larger you need a different barrel size, since crimping an oversized conductor into this barrel will not form a sound joint.

It is a non-insulated terminal with a plain copper finish, so the barrel is bare metal. If the termination sits where it could contact an adjacent conductor or a grounded surface, add heat shrink or an insulating sleeve over the barrel, or pick an insulated fork terminal instead. Inside a terminal block or an enclosed control panel where spacing is controlled, bare is normally how these get used.

A fork (spade) terminal like the A71FPF slides in under a loosened screw head without pulling the screw all the way out, which is why electricians use them on terminal strips, control relays, and device screws where access is tight. A ring terminal has to come off the stud entirely, but it cannot vibrate out, so it is the better call on vehicle, motor, and high-vibration connections. On a panel or thermostat subbase the fork is faster and is standard practice.

The barrel and tongue are copper with a plain, unplated finish. Bare copper will oxidize in damp or chemically active air, so for outdoor enclosures, wet rooms, coastal sites, or mechanical rooms with condensation, a tin-plated terminal holds up better. Plain finish is fine in dry, conditioned interior panels.

Yes. A non-insulated terminal needs the non-insulated (open barrel style) crimp die, not the color-coded insulated nest on a combination tool. Using the insulated die on a bare copper barrel under-forms the crimp and the wire pulls out. Match the die to the 22-16 AWG range the terminal is rated for.

The manufacturer part number is A71FPF, Sta-Kon's plain finish non-insulated fork terminal for 22-16 AWG. If the terminals in your existing panels are bare copper spades on control wiring, that number is the direct reorder. If the ones in place are colored (insulated), you need an insulated Sta-Kon fork instead.

Country of origin on the A71FPF fork terminal is the United States, which is what government, military, and federally funded institutional specs usually want to see on domestic-content line items.
