Sta-Kon A221M – Frequently Asked Questions
1) What wire gauge does the Sta-Kon A221M fork terminal accept?
The A221M takes 22 to 16 AWG stranded or solid copper wire. If your conductor is 14 AWG or larger, this barrel won't crimp down on it correctly and you need a larger terminal.
2) What screw size does the Sta-Kon A221M fork terminal fit?
It's sized for a No. 6 screw or stud. The fork slot slides around a #6 terminal screw without having to remove the screw completely, which is what makes it quicker than a ring terminal on a crowded control block.
3) Should I use a locking fork terminal or a ring terminal on a control panel?
A fork terminal goes on and off without pulling the screw out, so it's faster for panel work and service calls. The locking tangs on the A221M bite under the screw head to resist backing out under vibration. A ring terminal is still the better call where code or spec requires a captive connection that can't slip off a loosened screw.
4) Is the Sta-Kon A221M insulated?
No. It's a non-insulated copper terminal, so the crimp barrel is bare metal. Plan on heat shrink or tape over the barrel where adjacent terminals or a grounded enclosure wall are close enough to short against it.
5) Do I need a special crimper for the A221M non-insulated fork terminal?
Use a non-insulated crimp die, not the insulated color-coded nest. Non-insulated barrels are crimped with an indenter or a confined nest sized for the 22-16 AWG range; crimping one in an insulated die leaves an under-formed joint that pulls out.
6) What is the Sta-Kon A221M terminal made of?
Copper. Bare copper crimps cleanly onto copper conductors and gives you a low-resistance joint without the dissimilar-metal problem you get pairing aluminum hardware with copper wire.
