Conventional Products
<Issues>
●Standard Machine Screw
→ It does not have self-locking function and reliability in anti-loosening is low.
●With serration
→The load is attenuated with the series of notches on its bearing surface resulting in inadequate engagement to mating material.
●With lock adhesive
→The cost is high as a secondary process is required.
- Reliability
- 95(Based on standard machine screw Anti-lossening reliability
- Cost Index

BL Fastener H-Type
<Feature>
On the bearing surface, 3 sections are designed concave, these sections accommodate mating material and prevent rotational loosening
●Mating material is to be embedded in the recessed portions of BL Fastener, so mating part made of soft materials works best.
●No secondary process is required so the cost can stay low.
