8PC.SCREW EXTRACTOR SET M3~M50

An 8-piece screw extractor set, with a range from M3 to M50, is a comprehensive tool kit designed to remove broken or stripped screws, bolts, studs, or other threaded fasteners from materials such as metal, wood, or plastic. Here’s an overview of what such a set typically includes and how it’s used:

Components of an 8-Piece Screw Extractor Set (M3 to M50):

1. Screw Extractors: The set typically includes a range of screw extractors with different sizes and designs to accommodate various screw or bolt diameters, ranging from M3 to M50. These extractors are often made of high-speed steel (HSS) or cobalt steel for durability and strength.
2. Extractor Sizes: The set may contain extractors in incremental sizes to cover a wide range of screw or bolt diameters. Each extractor is labeled with its corresponding size or diameter, making it easy to select the appropriate tool for the job.
3. Drill Bits: Some screw extractor sets come with matching drill bits that are used to drill a hole into the broken or stripped screw or bolt before using the extractor. These drill bits are sized to match the extractor and are typically made of high-quality steel for drilling through various materials.
4. Tap Wrench or T-handle: A tap wrench or T-handle may be included in the set to provide a secure grip and precise control when using the screw extractors or drill bits. This tool allows for easy turning and maneuvering during the extraction process.
5. Storage Case: The set usually comes in a durable storage case or organizer to keep all the components organized and protected from damage or loss. The case may have labeled compartments for easy identification of each extractor size.

How to Use a Screw Extractor Set:

1. Drilling: Start by using the appropriate drill bit from the set to drill a hole into the center of the broken or stripped screw or bolt. The size of the drill bit should match the size of the extractor being used.
2. Inserting the Extractor: Once the hole is drilled, insert the screw extractor into the hole, ensuring it’s securely seated and aligned with the screw or bolt.
3. Turning the Extractor: Use a tap wrench or T-handle to turn the extractor counterclockwise. The reverse threads on the extractor will grip the inside of the screw or bolt and gradually loosen it from the material.
4. Removing the Screw or Bolt: Continue turning the extractor until the broken or stripped screw or bolt is fully removed from the material. Use caution to avoid applying excessive force, which could damage the surrounding material.
5. Clean-Up: After extraction, clean any debris or residue from the hole and surrounding area. Inspect the material for any damage and make any necessary repairs or adjustments.

Conclusion:

An 8-piece screw extractor set, ranging from M3 to M50, is a valuable tool kit for removing broken or stripped screws, bolts, studs, or other threaded fasteners from various materials. With a selection of extractors in different sizes and a matching drill bits, along with a tap wrench or T-handle for precise control, this set provides a comprehensive solution for tackling a wide range of extraction tasks. Whether in automotive, construction, or DIY projects, a screw extractor set is an essential tool for effectively and efficiently removing stubborn fasteners with ease.
