Irwin Industrial Tool Co 394100 Bolt Extractor Set 7-piece

Product Description

The IRWIN INDUSTRIAL TOOL CO 394100 is a 7-piece bolt extractor set engineered for removing fasteners that have been rounded off, rusted tight, or painted over. Each extractor features a 1/4 inch hex shank, allowing direct use with most power tools and impact drivers for faster removal. Reverse spiral flutes grip the fastener as torque is applied, biting deeper under load rather than slipping. The set is built from high carbon steel for durability across repeated use. A universal lobular design allows each extractor to engage a range of fastener types and sizes without requiring an exact socket match. A plastic storage case is included to keep the set organized between jobs.

This set is suited for maintenance technicians, HVAC service pros, plumbers, electricians, and general tradespeople who routinely encounter damaged or corroded fasteners during equipment teardown and repair. The 1/4 inch hex shank interface makes it compatible with standard power drill chucks and quick-change bit holders, reducing setup time in the field. The set is applicable across residential and light commercial service work wherever stubborn fasteners slow down a job.

Installation Notes

Always de-energize or power down any equipment before attempting fastener removal. Use appropriate eye protection when working with bolt extractors, as damaged fasteners may shed metal fragments under load. Select the extractor size that fits snugly into the fastener recess before applying reverse-direction torque. Start at a lower speed setting when using with a power tool to allow the flutes to seat properly before increasing torque.
