Screw extractor set ELORA 35S-. Made in Germany

Screw extractor set, also known as an easy-out or bolt extractor, is a specialized tool used to remove broken or stripped screws, bolts, or studs from materials. It is designed to grip the damaged fastener and extract it by turning it counterclockwise.

A screw extractor typically consists of a hardened, tapered, and spiral-fluted shaft. The tapered end is inserted into a pilot hole drilled into the center of the damaged screw or bolt head. As the extractor is turned counterclockwise, the flutes of the tool bite into the fastener, providing grip and extracting it from the material.

Screw extractors come in various sizes and are made from high-strength materials such as high-speed steel or cobalt steel to withstand the forces involved in removing stubborn fasteners. They are available as individual tools or as part of a set with multiple sizes to accommodate different screw or bolt diameters.

In addition to screw extractors, there are also specialized extractors designed for removing stripped or damaged screws with specific head types, such as Phillips head or Torx head screws. These extractors often have unique shapes or features to engage with the specific screw head design and facilitate removal.

Screw extractor set ELORA 353S

The ELORA screw extractor set you mentioned appears to be a set of screw extractors designed specifically for extracting broken screws and bolts with right-hand threads. The set includes three different sizes (351S 5, 352S 6, and 353S 8) with varying extractor lengths.

Here’s a breakdown of what each set contains:

1. ELORA 351S 5:
– Extractor Sizes: 350-6, 350-8, 350-11, 350-14, 350-18
– This set includes five extractors suitable for removing broken screws and bolts with right-hand threads. The numbers following the “350-” indicate the diameter of the screws or bolts the extractors can handle, such as 6mm, 8mm, 11mm, 14mm, and 18mm.

2. ELORA 352S 6:
– Extractor Sizes: 350-6, 350-8, 350-11, 350-14, 350-18, 350-24
– This set builds upon the previous one and includes six extractors, including the sizes mentioned earlier, with the addition of a 24mm extractor.

3. ELORA 353S 8:
– Extractor Sizes: 350-6, 350-8, 350-11, 350-14, 350-18, 350-24, 350-33, 350-52
– This set is the most comprehensive and includes eight extractors, including all the sizes mentioned earlier, with the addition of a 33mm and 52mm extractor.

These extractor sets are made from chrome vanadium (58CrV4 / 1.8161), which is a durable and high-strength material suitable for withstanding the forces involved in extracting broken fasteners. They are designed to grip the damaged fasteners securely and allow you to turn them counterclockwise for removal.

• For extracting broken screws and bolts with right-hand thread
• Chrome vanadium 58CrV4 / 1.8161
• Made in Germany

When using these extractors, ensure that you drill a pilot hole into the center of the broken screw or bolt head, choose the appropriate extractor size, insert it into the hole, and turn it counterclockwise using a wrench or pliers until the fastener is removed.

How to use screw extractor?

Using a screw extractor involves several steps. Here’s a general guide on how to use a screw extractor:

1. Select the right size: Screw extractors come in various sizes, so choose the one that matches the screw you want to remove. Ensure the extractor is smaller than the screw itself.
2. Prepare the materials: Gather the necessary tools, including the screw extractor, a drill, a drill bit slightly smaller than the extractor, a wrench or pliers, and a hammer.
3. Drill a pilot hole: Use the drill and a small bit to create a pilot hole in the center of the screw head. The hole should be deep enough for the extractor to grip, usually around 1/8 to 1/4 inch.
4. Attach the screw extractor: Insert the screw extractor into the pilot hole. The tapered end of the extractor should face outwards. Push it into the hole until it feels secure.
5. Apply force counterclockwise: Using a wrench or pliers, turn the screw extractor counterclockwise. Apply steady, firm pressure while turning to grip the screw firmly.
6. Use a hammer (optional): If the screw is stuck and difficult to turn, you can lightly tap the top of the extractor with a hammer. This helps create additional friction and aids in loosening the screw.
7. Rotate and remove the screw: Continue turning the extractor counterclockwise with the wrench or pliers. As you rotate, the extractor will catch onto the screw threads and gradually loosen it. Keep applying consistent pressure until the screw is completely removed.
8. Clean the area: Once the screw is out, clean the area and remove any debris or remnants left behind.

It’s important to note that screw extractors may not be effective in all situations, especially if the screw is severely stripped or seized. In such cases, you may need to explore alternative methods or seek professional assistance.
