ApplicationFor stripped screws that cannot be removed with an ordinary tool
- A tool that can remove cross-recessed head machine screws and hex socket head cap screws with crushed or stripped recesses that cannot be removed by ordinary tools.
- The dedicated bit SKEIB is used to make grooves in damaged recesses which can be used to turn and remove the screws. For details, refer to "How to Remove Screws".
- Use it with the dedicated bit SKEIB for making grooves and the impact screwdriver SKEID for turning the screw in the direction of loosening 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.
Compatible with 2 types of recesses: hexagonal and cross-recessed.
SKEIB--------For Hex Sockets
SKEIB-SPHSKEIB-MPH----For Cross-Recessed Sockets
- SKEIB, SKEIB-SPH, SKEIB-MPH and SKEID can be purchased individually. SKEIBSKEIB-PHSKEID
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.
- Do not use SKEIB-SPHSKEIB-MPH for screws with high surface hardness due to heat treatment. The bit may be damaged.
- 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.
