The WILLIAMS COMFORT PRODUCTS EX-21A is a screw extractor designed to remove damaged, stripped, or broken fasteners that can no longer be turned with standard drive tools. Built for use with a 1/8 inch drive, this extractor gives technicians a reliable way to back out problem fasteners without damaging surrounding hardware or threading. The tool is sold individually and is suited for use in tight service spaces where broken fasteners are common, such as during equipment panel removal, motor replacement, or general mechanical service work. At 0.02 pounds, it is a compact, lightweight addition to any service kit.
The EX-21A is appropriate for use across HVAC, plumbing, electrical, and general mechanical service applications where stripped or seized screws are encountered. It is particularly useful during equipment teardown and repair scenarios where fasteners have corroded, been overtightened, or had their drive heads damaged. Licensed technicians and experienced service professionals who perform regular equipment maintenance will find this extractor a practical hand tool to keep on the truck.
Designed as a general-purpose screw extractor for use with 1/8 inch drive fasteners encountered in trade service and repair applications.
Screw extractors are typically used by licensed technicians during equipment service and repair. Before extracting any fastener, power down all electrical circuits and shut off any gas or water supply lines in the immediate work area. Use a center punch and appropriately sized drill bit to prepare the damaged fastener before seating the extractor, following standard hand-tool extraction procedures. Always wear appropriate eye protection when drilling into or extracting broken fasteners.
