When properly sized, these can go directly into and bottom out in a thermowell. All probes include a screw terminal block for easy connection of insulated copper extension wire. Replacement probes (without head assembly) are available as well as a "spring-loading" option which allows for the probe to bottom out in a thermowell for quicker and more accurate response.
