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 (R)" features two types of screw threads with different nominal diameters aligned on the same axis (with a common pitch), allowing for self-tapping in the threaded sections of both the workpiece and the counterpart material. 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 a lightweight fastening structure. 【Features】 ■ Reduces loosening after axial force decrease and creep ■ Achieves lightweight products ■ Reduces fastening costs ■ Prevents misalignment as the screw itself ensures alignment, eliminating the need for positioning pins or similar tools ■ Allows for initial fastening through axial force *For more details, please refer to the PDF document or feel free to contact us.
