The IRWIN IR394001 is a 5-piece Bolt-Grip screw and bolt extractor set designed to remove damaged, rounded, or seized fasteners that standard tools cannot grip. Built for professionals who encounter frozen or stripped bolts in the field, this set provides a reliable mechanical solution for extracting fasteners without drilling out or destroying the surrounding material. It is a standard inclusion in the tool inventory of HVAC technicians, plumbers, electricians, and general mechanical contractors who regularly work with corroded or over-torqued hardware.
This extractor set is suited for residential and commercial service work where damaged fasteners are common — equipment installations, retrofits, and repair calls on aging systems. It is particularly useful when servicing older mechanical equipment where bolts and screws have corroded in place over time. The 5-piece configuration covers a range of fastener sizes in a single kit, reducing the need for multiple individual extractors on a service call.
Designed as a general-purpose screw and bolt extractor set compatible with standard drill drivers and extraction workflows for a range of common fastener sizes encountered in mechanical, electrical, and plumbing service work.
Bolt and screw extraction work should be performed by a qualified tradesperson familiar with fastener removal techniques. Always de-energize equipment and relieve system pressure before attempting fastener removal on live mechanical or electrical assemblies. Follow the extractor manufacturer instructions for proper bit engagement and rotation direction to avoid breaking the extractor in the fastener. Refer to applicable codes such as the NEC or IFGC when working on code-governed systems.
