Williams Comfort Products EX-21B Screw Extractor

Product Description

The WILLIAMS COMFORT PRODUCTS EX-21B is a screw extractor designed for removing damaged, stripped, or broken fasteners from threaded applications. This tool accepts a 3/16 inch drill and is used to back out fasteners that can no longer be driven by conventional means. At 0.02 pounds, it is a lightweight, single-unit hand tool suited for technicians who work across HVAC, plumbing, electrical, and general mechanical service. The EX-21B provides a reliable mechanical grip on compromised fastener heads, allowing controlled extraction without damaging surrounding material.

This screw extractor is appropriate for residential and light commercial service environments where stripped or broken fasteners are encountered during equipment repair, panel access, or component replacement. It is a standard tool for trade professionals who need to recover fasteners in tight or awkward service locations. The EX-21B is sold as an individual unit, making it a direct replacement or addition to an existing extractor set.

Installation Notes

Screw extractors are typically used by licensed HVAC technicians, plumbers, electricians, and general mechanical service professionals. Before use, ensure the work area is de-energized and any associated system is shut down per standard lockout/tagout procedures. Use the appropriate drill to create a pilot hole in the damaged fastener before seating the extractor. Apply steady, controlled reverse torque to avoid breaking the extractor in the bore.
