  • Single 17/64 in stud hole simplifies termination
  • Rated 1000 V and 194 °F for demanding circuits
  • Hex head allows secure torque with standard tools

Thomas & Betts STC0208 Straight Tang Connector

This mechanical connector joins a single copper conductor ranging from 8 AWG to 2 AWG. The body uses electrolytic copper for reliable conductivity in electrical and industrial wiring tasks. It accepts a 17/64 in stud and operates at up to 1,000 V with a maximum temperature of 194 Degrees F. The straight tang design provides a direct termination path.

Hex head and single hole simplify installation

The connector features a hex head style that allows standard tool engagement for secure tightening. With one hole of 0.27 in diameter, alignment is straightforward without hole spacing concerns. Tongue dimensions of 0.75 in length, 0.5 in width and 0.09 in thickness fit standard lug configurations. These details reduce assembly time on the job site.

Suited for electricians terminating 2-8 AWG copper

This part fits professionals needing a single-conductor, straight tang lug for copper wire within the stated gauge range. It is not for aluminium conductors, multi-conductor cables or applications exceeding 1,000 V. Builders requiring angled tangs, multiple holes or larger stud sizes should look at something else.

Questions about this item

Will the copper tang need periodic re-torquing to stay tight?

The connector is made from electrolytic copper and uses a hex-head set screw; standard practice is to check torque after initial installation and whenever the circuit is opened for service.

What stops me from running it continuously at the 1000 V rating?

The maximum operating temperature is 194 degrees F, so sustained loads that push the conductor above that limit will be the first constraint.

How hot does the tang get when it carries full load all day?

The body is rated to 194 degrees F maximum; actual temperature rise depends on conductor size, ambient conditions and airflow around the 0.75 in tongue.
