About Irwin Hanson

When a bolt snaps flush with the surface, a thread strips under torque, or a fastener corrodes beyond recognition, professionals reach for Irwin Hanson tools. As a cornerstone sub-brand of IRWIN Industrial Tools, Hanson has built a decades-long reputation for manufacturing threading and extraction tools that tradesmen, mechanics, and machinists trust on the job every single day. The name Hanson is virtually synonymous with taps, dies, and screw extractors — the unsung heroes of any serious toolbox.

A Legacy of Threading Excellence

Irwin Hanson's roots run deep in the American tool-making tradition. The Hanson name became a benchmark for quality in threading tools long before it was brought under the IRWIN umbrella, and that heritage still shows in every product. IRWIN Industrial Tools has consistently set the standard for delivering precision across all threading applications, and the Hanson line carries that torch with tools made from high carbon steel designed to cut cleanly, hold their edge, and perform reliably under real-world conditions.

At the heart of the Hanson lineup are the brand's celebrated Tap and Die Sets. Whether you're chasing a damaged thread on an exhaust manifold stud, cutting new threads in raw stock, or tackling a mix of fractional, metric, and pipe thread applications, Irwin Hanson sets cover the full spectrum. Their comprehensive kits — some spanning over 100 individual pieces — include plug taps, hex dies, tap wrenches, and pitch gauges, making them a go-to solution for both professional shops and serious DIYers.

When Fasteners Fight Back

No tool category showcases Irwin Hanson's engineering ingenuity quite like their Screw Extractors. Broken bolts and stripped fasteners are an inevitability in automotive and industrial work, and Hanson's extraction lineup is built to handle them all. The range includes spiral flute extractors for common fasteners, multi-spline extractors for higher-torque situations, and bolt extractors designed for partially exposed fasteners — often paired with left-hand cobalt drill bits that can back a fastener out during the drilling process itself.

For more stubborn situations — like a corroded stud broken off deep in an engine block — Irwin Hanson's Stud Extracting Tools provide a specialized solution. These tools are engineered specifically for the unique geometry of studs, offering more purchase and control than a general-purpose extractor in tight, high-stakes applications.

Beyond Threading: A Complete Tool Lineup

While threading and extraction tools define the Hanson brand identity, the lineup extends further. Irwin Hanson Drill Bits — including high-speed steel and cobalt variants — are designed to work in concert with taps and extractors, pre-drilling precisely sized pilot holes for clean, accurate threading. And for gripping, bending, and manipulating materials, Irwin Hanson Pliers round out the offering with the same commitment to durability and ergonomic design that defines every tool in the lineup.

From threading a new bolt hole to rescuing a seized fastener buried deep in an engine bay, Irwin Hanson tools are built with the professional tradesman in mind — and they perform like it.
