Terminal Specifications

The Sta-Kon B14-12 is a non-insulated ring terminal designed for 18-14 AWG copper conductors. It accepts wire sizes from 18 AWG up to 14 AWG and features a 1/2 inch stud hole for secure mounting. The terminal is sold in a pack of 100 pieces for volume wiring tasks.

Build and Connection

A serrated barrel provides mechanical grip during crimp termination while the tin-plated copper body resists corrosion. The bare metal construction has no insulation coverage and carries a maximum operating temperature of 221 degrees F. UL listing E9809 and CSA certification confirm compliance with recognised safety standards.

Upgrade Context

This terminal replaces loose wire ends or insulated connectors where high heat or frequent disassembly would degrade plastic sleeves. The jump is worth it when a permanent, vibration-resistant ring lug is required on a 1/2 inch stud and the circuit operates up to 600 volts. It does not suit applications needing insulated barrels or wire gauges outside the 18-14 AWG range.

Questions about this item

What wire gauges does the 1/2" stud ring terminal accept?

The terminal is rated for 18 AWG minimum and 14 AWG maximum copper conductors.

What are the barrel length and stud hole spacing for this ring terminal?

The serrated barrel measures 0.32 in long and the hole spacing is 0.38 in for a 1/2" stud.

How should the B14-12 terminal be crimped onto the wire?

Strip the conductor to match the 0.32 in barrel, insert fully into the serrated barrel, and compress with a calibrated crimp tool — skipping full insertion is the common error.
