Sta-Kon B223ML LFTHD RL NOINS LCKFRK BLT8,18-14AWG

The B223ML is sized for #18-14 AWG conductors. That covers the common control and signal wire range, so one part number handles 18, 16 and 14 gauge runs on the same panel instead of stocking three terminals.

No insulation on this one. The B223ML is a non-insulated locking fork terminal, which means bare metal at the barrel and no color-coded sleeve. In tight terminal strips where adjacent terminations are close, you either sleeve it with heat shrink yourself or move to an insulated fork of the same wire range.

A locking fork splits the difference. Like a plain spade, it slides under a screw head without removing the screw, so you can land or swap a wire on a live-ish terminal block fast. Unlike a plain spade, the locking tangs grip under the screw head and resist backing out under vibration. A ring terminal is still the most secure (the screw has to come all the way out to lose the wire), so on motor connections or anything that gets shaken hard, a ring is the safer call. The B223ML is the fork choice for #18-14 AWG on #8 screws.

Copper. That matters for two reasons: it keeps resistance low at the crimp, and it pairs correctly with copper conductors, so there is no dissimilar-metal issue at the termination. It is not rated for aluminum wire.

Yes, use a non-insulated crimp die, not the color-coded insulated-terminal nest. Non-insulated barrels are crimped with an indenter or oval die that forms the bare barrel directly; squeezing one in an insulated-terminal jaw gives an under-formed crimp that pulls out. Match the die to the #18-14 AWG range.

Country of origin is the United States, which is what a government, healthcare or education procurement officer needs for domestic-preference purchasing requirements on an electrical bill of materials.
