ApplicationFor stripped screws that cannot be removed with an ordinary tool
- A tool that can remove hex socket head cap screws with crushed or stripped hex sockets that cannot be removed by ordinary tools.
- Used to create grooves in damaged recesses which can be used to turn and remove the screws. For details, refer to "How to Remove Screws".
- Can be used with the impact screwdriver SKEID to turn screws in the loosening direction by applying impact.
- Can also remove flat head screws that cannot be gripped with a tool such as a wrench or screws in counterbored holes.
- The recess is compatible with hex socket screws.
Usage ExampleFor cases where recesses are damaged due to tool cam-out.
For cases where recesses are damaged due to turning tools with shallow contact.
For cases where recesses are crushed due to rust or corrosion from long-term exposure to outdoor environments.
For cases where recesses are damaged due to attempts to forcibly remove tightly stuck screws.
For cases where recesses are damaged due to usage of incorrect sizes of tools.
Precautions for Use
- Do not use for purposes other than removing screws with damaged recesses.
- Use SKEIB in combination with SKEID.
- Use a bit suitable for the recess of the screw.
- Hitting with a hammer will transmit the impact to the part where the screw is attached. The impact may be absorbed without creating a groove, or the mounting area may be damaged.
- Do not use for screws with low recess strength such as resin screws, as they may be damaged further.
- Striking with excessive force may damage the screw further, or damage the bit.
- The tip of SKEIB is sharp, so be careful to avoid injury.
- When using a hammer, be careful not to accidentally hit your hands or fingers.
- Do not use in locations exposed to live wires, as it is made of metal.
- Be sure to wear safety glasses while working.
How to Remove Screws① Place the applicable stripped screw removal bit SKEIB vertically to the damaged recess and hit the end of the shaft with a hammer to form a groove on the screw head.
② Mount SKEIB on the impact screwdriver SKEID. Place the SKEIB tip vertically against the groove made in the screw head, firmly hold the SKEID grip, and hit the end with a hammer to rotate the SKEID tip up to 45°＊1 and loosen the screw.
＊1： Gently push the SKEID adapter in while turning it, and align the △ mark in the loosening direction. L left rotation / R right rotation
The rotational direction of SKEID may change depending on the impact. To avoid this, hammer while applying force in the desired direction.
