Irwin 394002 Bolt Extractor Set 5 Piece 3/8 Inch Drive

Product Description

The IRWIN INDUSTRIAL TOOL CO 394002 is a 5-piece bolt extractor upgrade set built for removing damaged, rounded, and seized fasteners. Each extractor features reverse spiral flutes that bite down under turning force to maximize grip on problem fasteners. The set is made from high carbon steel for extended service life under repeated use. A universal lobular profile engages all common fastener types. The 3/8 inch square drive shank is compatible with hand ratchets, impact wrenches, and air ratchets, while the hexagonal flats accept flat wrenches, pliers, adjustable wrenches, standard sockets, and VISE-GRIP locking pliers. Mechanics, HVAC technicians, and plumbers working on corroded or damaged hardware will find this set a reliable addition to a service kit.

This set is suited for both residential and light commercial service work where damaged or rounded fasteners are a routine obstacle. The included extractors cover a practical range of common metric and fractional sizes: 8mm, 10mm, 13mm, 19mm, 5/16 inch, 11/16 inch, and 3/4 inch bolt sizes, all in the 3/8 inch drive size. The dual-drive design means the same extractor works with a ratchet in tight spaces or with locking pliers when a ratchet cannot seat properly. Trade professionals doing equipment removal, panel work, or piping disassembly will encounter every one of these fastener sizes regularly.

Installation Notes

Select the extractor size that most closely matches the damaged fastener before applying torque. Ensure the drive tool is fully seated on the extractor before turning to avoid slippage. When using with an impact wrench, verify the extractor is rated for impact use and that surrounding components are clear of the work area. Disengage power tools and release all pressure from the system before attempting fastener removal on live mechanical or plumbing assemblies.
