NITTOSEIKO CO., LTD. (Headquarters: 20, Umegahata, Inokura, Ayabe, Kyoto. President : Makoto Araga, TSE Prime, https://www.nittoseiko.co.jp/) has released the “NC Grip” anti-loosening screw. Orders will begin to be accepted from November 1, 2024.
|
【Product Overview】
□A self-locking screw with a coating of
microencapsulated epoxy resin on the threaded part.
□The microcapsule is cracked when screwed in, and
the epoxy resin oozes out and hardens to prevent
loosening.
□Coating is possible on all types of screws, including
small screws and tapping screws.

|
【Examples of Usage】
□Area to be made non-decomposable
□Where it is used for vibration and heat
 
|
【Application Example】
□In-vehicle display
□Door Components
□Medical Devices
□Home appliances |
□Battery pack
□Compact Camera
□Transmission
□Amusement devices, etc. |

Features
Dramatic Reduction in Hardening Time
|
□The use of a new pre-coating agent improves
the quick-drying properties of epoxy resin.
The curing time required to obtain a loosening torque (the torque required to reverse the screw) that exceeds the tightening torque is about one sixth that of our conventional product (NK Grip).
<12 hours later → 2 hours later>
|
 |
Maintains its loosening-prevention effect
|
□Loosening Torque Performance
The maximum instantaneous loosening torque after 72 hours of tightening is almost the same as that of the conventional product (NK Grip), providing a powerful loosening prevention effect.
|
|
□The planting bolts can be fixed in place
with adhesive
Even for a stud bolt that does not have a head and is difficult for axial force to act on, it has a return torque performance that exceeds that of conventional products (NK Grip).
