Screw Extractor Set Irwin IW4041011 — 10-piece set for removing damaged and rounded screws

Irwin IW4041011 is a 10-piece screw extractor set designed to remove damaged, rounded or seized screws and bolts. The set contains a selection of extractors sized to match different screw diameters and thread forms commonly found in workshop, automotive and household applications. It is intended to recover fasteners without enlarging or destroying the surrounding hole, reducing the need for re-tapping or part replacement.

Advantages

The set provides a range of extractor sizes in a compact case, enabling selection of the correct tool for various screw diameters. Each extractor is produced from heat-treated steel for higher torsional strength and wear resistance. The spiral flute geometry bites into damaged screw material to provide reliable grip during counterclockwise extraction. The set minimizes further damage to workpieces by allowing removal of fasteners without excessive drilling or thread removal.

Suitable for

• Removing rounded or damaged screw heads in metal and soft alloys
• Recovering seized or rusted bolts in automotive maintenance
• Workshop repair tasks where preserving existing threads is important
• DIY projects involving stripped screws in wood, plastic or metal

Key specifications

• Set composition: 10 extractors covering a range of small to medium screw diameters
• Material: heat-treated alloy steel for enhanced strength
• Flute type: tapered spiral flutes for reverse-thread gripping action
• Compatibility: suitable for use with tapered drill pilot holes and manual or powered drivers where applicable
• Storage: compact carrying case for organized transport and storage

How to use

Select an extractor size that matches the damaged screw diameter. If required, center-punch and drill a small pilot hole into the screw to provide a starting point for the extractor. Insert the extractor into the pilot hole and apply steady counterclockwise torque using an appropriate wrench, T-handle or driver until the extractor bites and turns the screw out. For stubborn fasteners, apply penetrating lubricant and allow time to work before attempting extraction. Follow safe torque limits to avoid breaking the extractor inside the screw.

Usage recommendations

Use progressively larger extractors if the first choice does not hold; avoid applying excessive force to prevent tool breakage. Maintain pilot hole alignment and use suitable personal protective equipment such as eye protection when drilling and extracting fasteners.
