Colorless Tight(R) screw for the abolition of iron color insert nuts

Self-tapping screws that can eliminate iron color insert nuts! No need for creep measures, achieving cost and labor reduction, as well as lightweight fastening structures!

The "Colorless Tight®" differs from conventional screws by having two types of screw threads with different nominal diameters aligned on the same axis (with a common pitch), allowing for self-tapping in the screw sections of both the workpiece and the counterpart. This action prevents loosening and play in the workpiece when axial force decreases or creep occurs. As a result, the measures against creep that were previously implemented using iron collars or insert nuts become unnecessary, leading to reductions in cost and labor, as well as lightweight fastening structures. 【Features】 ■ Reduces loosening after axial force decrease and creep ■ Achieves weight reduction of products ■ Realizes reduction in fastening costs ■ Prevents misalignment by the screw itself, eliminating the need for positioning pins or other alignment tools ■ Allows for initial fastening through axial force *For more details, please refer to the PDF document or feel free to contact us.
