Specifications/Overview of Nuts

■Loosening prevention type

• This Nuts has a loosening prevention agent applied to the inside of the tap, reducing loosening caused by vibrations during transportation or equipment operation.
• Anti-loosening adhesive is an anaerobic adhesive encapsulated in microcapsules. It effectively prevents loosening, but please note that it requires time to harden (72 hours at room temperature 25°C) and loses its effectiveness onceloosened.
• Resin coating is a coating of resin that conforms to the shape of the thread. It does not have the same loosening prevention effect as adhesive types, but it does not require curing time and can be used repeatedly.

Nuts Anti-loosening adhesive type			・Effectively prevents loosening ・However, once loosened, the effect is lost  ・After tightening, the adhesive needs time to harden (approximately 72 hours at room temperature 25°C)	7.6N・m	Test conditions: Tightened to 6.8 N m, dried at room temperature (25°C) for 72 hours, then loosened the bolts. Measured with HNTTV5-5.
Anti-loosening resin coated type			· The anti-loosening effect can be used repeatedly (the anti-loosening effect will decrease with repeated use) · The anti-loosening effect is immediately apparent after tightening	6.5N・m	Repeated use will reduce the effectiveness of the loosening prevention function. 5th return torque: 6.2 N m (measured with HNTTZ5-5)

* The return torque value is a reference value. The value may vary depending on the clearance between the bolt and Nuts.

How to Use of Nuts

This product is a post-insertion Nuts. It can be inserted into the groove after assembly.
It will not fall off even if the frame is placed vertically.
The built-in spring mechanism prevents slipping. It can be easily moved within the groove by lightly pressing with your hand.

Selection Support Information of Nuts

■Difference between first-in and last-in

- MISUMI offers a wide range of aluminum frame Nuts, including both first-in and last-in types. Use them according to your application.

First-in: Install from the groove end face before assembly. The wide design means there is little play inside the groove, making bolt tightening easy.

Post-insertion: Can be inserted into the groove after assembly.

■If the aluminum frame becomes stuck and cannot be removed,
you can remove it by hooking a hex wrench into the hole in the Nuts and turning it at a right angle to the groove.
