Dimensions Insertion spindle for manual insertionand electric screwdriver

Tangless screw thread insert No tang break-off required No risk when drilling blind holes with low remaining wall thickness No need to remove tangs Reduced inspection work No risk due to tangs remaining in the component Working sequence shortened by dispensing with tang removal step Large parts do not have to be turned upside down

Insertion notch on both sides Bi-directional insertion No directional restriction Insertion notch at back acts as extraction notch and aligning notch Special HELICOIL Tangless extraction tools are provided for easy removal and

alignment of the thread inserts

Compatible with the HELICOIL plus system Same HELICOIL holding threads No change in design No need for new taps
