York 021-33190-100 Bolt Terminal

1. Advantage：

This YORK bolt terminal (P/N 021-33190-100) is a machined electrical terminal bolt used for secure power and control circuit connections on YORK chiller equipment. Terminal bolts carry the mechanical clamping force that keeps high-current connections tight-a loose or corroded terminal is a leading cause of hot spots, intermittent faults and contactor failures. Replacing worn terminal hardware with the OEM bolt restores proper torque capacity and clean electrical contact at the connection point.

Electrical connections on chiller motor leads and contactor terminals carry serious current-when the clamping hardware degrades, resistance climbs and heat follows. The 021-33190-100 is the OEM terminal bolt engineered to hold that joint tight at the correct clamping load. Replacing a scorched or pitted bolt during electrical service is cheap insurance: it prevents the connection from becoming the next hot spot that takes down a contactor or a motor lead.

3.Our Advantage

Terminal hardware is easy to overlook during electrical repairs-technicians often reuse the old bolt and then wonder why the connection overheats again. We supply the correct OEM terminal bolt so the repaired connection meets original spec. If you are upgrading or replacing a terminal block, we can help confirm the bolt size matches your application. Add small hardware like this to any parts order and it ships with minimal freight impact.

The first thing a good service tech does on an overheated connection is replace the hardware, not just retighten it-metal that has been heat-cycled once will fail again. We stock the OEM YORK bolt so you do not have to settle for a hardware-store substitute with different thread or grip length. If you are working on a specific connection and are unsure of the bolt size, send us a photo of the terminal block and we will match it.
