Screw Extractor Set JOBIprofi W15105 for Broken Screws M3–M18, 5 pieces

JOBIprofi Screw Extractor Set W15105 contains five hardened extractors designed to remove broken, rusted or stripped screws and bolts with metric thread sizes from M3 to M18. The set is intended for workshop and repair environments and allows technicians and DIY users to extract damaged fasteners using a drill to create a pilot hole and a wrench to turn the extractor. Components are made for repeated use under mechanical stress and cover common screw sizes encountered in machinery, automotive and household repairs.

Advantages

The set includes five extractors sized to match a broad range of metric fasteners, reducing the need for improvised removal methods. Each extractor has a tapered, left-hand threaded profile that grips into a drilled pilot hole for reliable torque transfer while turning counterclockwise to remove the damaged screw. Hardened steel construction provides wear resistance and durability during repeated extractions. The compact set is suitable for bench work or mobile toolkits and is compatible with standard drills and wrenches.

Suitable for

• Removing broken or sheared screws and bolts in mechanical assemblies
• Extracting rusted or seized fasteners in automotive maintenance
• Repair and maintenance tasks in workshops and industrial settings
• DIY household repairs where screws are stripped or damaged

Key specifications

• Number of pieces: 5 extractors covering metric sizes
• Compatible thread size range: M3–M18
• Material: hardened steel for extraction durability
• Design: tapered, left-hand threaded extractor profile
• Drive method: requires drill for pilot hole and wrench for turning

How to use

Select the extractor that corresponds to the damaged fastener size. Drill a small concentric pilot hole into the center of the broken screw or bolt using an appropriate drill bit. Insert the extractor into the pilot hole and, using a wrench or tap handle on the extractor shank, turn counterclockwise to allow the left-hand threads to bite and back the fastener out. Apply steady, controlled torque to avoid snapping the extractor; if necessary, use penetrating lubricant and progressively larger extractors within the set for more secure engagement.

Usage recommendations

Use eye protection and clamp the workpiece securely before drilling. Start with a small pilot hole and increase size only as required. For corroded or seized fasteners, apply penetrating oil and allow time to soak before extraction. Avoid excessive impact force on the extractor; if high torque is needed, heat the surrounding material where appropriate and safe. Store extractors in a dry place to prevent corrosion and inspect for wear before use.
