Screw/Bolt Extractor Gedore 7690880

Made from chrome-vanadium steel with a hardness of 35 HRC, the Gedore 7690880 screw/bolt extractor is intended for extracting damaged or broken screws and bolts. The tool is designed to grip into a drilled central hole and remove seized fasteners by turning counterclockwise; penetrating oil may be required for stubborn bolts. Always select the largest extractor size that fits the drilled hole for best results.

Advantages

The extractor is manufactured from chrome-vanadium steel for wear resistance and consistent hardness. Its left-hand twist profile provides a secure grip in a pre-drilled central hole, allowing removal of damaged or stripped screws and bolts. The tool is compatible with common workshop procedures and can be used with standard drills and turning tools.

How to use

Drill a central hole in the broken bolt sized according to the extractor you intend to use. Insert the bolt extractor into the drilled hole and turn it counterclockwise until it bites into the metal and begins to back the fastener out. If the bolt is seized or corroded, apply penetrating oil before attempting extraction. Choose the largest extractor that fits the drilled hole to maximize gripping surface.

Recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. Ensure the drill is perpendicular to the bolt when creating the central hole to reduce the risk of slippage. If excessive force is required, assess the fastener and surrounding parts to avoid additional damage.
