Screw & bolt extractor set YATO YT-0620, 4 pcs, chromium-vanadium steel, black case

YATO YT-0620 is a 4-piece screw and bolt extractor set made from chromium-vanadium steel and supplied in a compact black case. The set is intended for removing damaged, rounded or seized screws and bolts and provides a simple solution for extracting stubborn fasteners without damaging surrounding materials. The tools are heat-treated and finished for improved durability, and the case keeps the extractors organized and protected when not in use.

Advantages

The chromium-vanadium steel composition delivers high strength and wear resistance appropriate for repeated extraction tasks. Heat treatment enhances toughness and reduces the risk of tool failure under torque. The included black storage case offers portability and neat storage, preventing loss of small parts. Sizes in the 4-piece set cover a range of common screw and bolt diameters, enabling flexible use across different repair and maintenance jobs.

Suitable for

• Automotive repair: removing rounded or seized screws and bolts on engines, chassis and bodywork
• Workshop maintenance: extracting damaged fasteners during machinery servicing
• Home repair: removing stripped screws in furniture, appliances and fixtures
• Industrial maintenance: maintenance tasks where safe removal of fasteners is required

Key specifications

• Set composition: 4 extractors covering a range of small to medium fastener sizes
• Material: chromium-vanadium (Cr-V) steel for strength and wear resistance
• Surface finish: dark / black oxide or similar protective finish to reduce corrosion
• Storage: compact black case for organized transport and storage
• Intended use: manual extraction of damaged, rounded or seized screws and bolts

How to use

Select the extractor size that fits the damaged screw or bolt and secure the workpiece to prevent movement. If necessary, clean the damaged fastener and apply penetrating oil to ease removal. Drill a small pilot hole in the center of the damaged screw head if required, then insert the extractor into the hole and turn counterclockwise using the appropriate driver or wrench. Apply steady, controlled torque until the fastener loosens and can be removed. After use, clean the extractors and return them to the case for storage.

Usage recommendations

For best results, use with appropriate hand tools and take safety precautions such as eye protection. Apply penetrating lubricant and allow time to penetrate when dealing with corroded or seized fasteners. Avoid excessive force that could break the extractor; if an extractor shows any signs of damage, replace it to prevent further issues.
