■ Introduction

It is a fastener that fastens to the base material (female thread) where the screw is not formed. It has a self-tapping function that allows for fastening while forming a thread on the base material (female thread). The product standard is designed to be safe for molding from M4 to M20. Accordingly, it can reduce production costs through process reduction and reduction of overall assembly costs and quality costs of customers by omitting the tapping process of the counterpart base material (on female thread).

■ Features

① Excellent resistance to loosening.

    (No need for lock washer or adhesive)

② Fast fastening with low torque during thread formation

③ Excellent thread formation of strong base material

    (female thread)

④ Reusable

⑤ Excellent mechanical properties (strength can be applied

    according to the counterpart)

⑥ Overall costs saving (assembly costs and tapping of

     counterpart base material)

⑦ Excellent vibration resistance

⑧ Fastening with high torque compared to mechanical

    properties

⑨ Excellent assembly with counterparts

⑩ Excellent reduction in assembly costs 

    and working time

⑪ Excellent alignment of the axis with the counterpart

    when fastening

■ Introduction

It is a fastener that can be adjusted and tightened (misalignment accommodating thread) even if the center is not aligned with the counterpart, and it provides such functions as preventing jams and cross-threading of threads during assembly. The product specifications are designed to be safe to mold from M4 to M16. Accordingly, it is not subject to the condition of unstable fastening position, and it can reduce quality costs with optimized specifications for products with high production costs and high base material (female thread) processing costs by shortening the working time as there is no need for temporary fastening as it is not fastened like general bolts.

■ Features

① Excellent assembly in unstable fastening position

② Excellent self-correction (adjustment) even when the bolt

     is inclined (prevents cross-threading)

③ Bolt and nut threads are engaged when the screw
    misses its markExcellent fastening prevention

   (prevents jamming)

④ It is excellent in preventing the screw threads of bolts 

    and fasteners from being cut short by 

   preventing cross-threading and jamming.

⑤ It is not affected by excessive paint application, 

     and excellent performance is maintained.

⑥ It is excellent in shortening working time as there is no

    need for temporary fastening.

⑦ Self-correction (adjustment) of the center of the bolt and

     the center of the female thread is excellent.

⑧ Excellent assembly with counterparts
