6 Series Pre-Assembly Insertion Nut for Aluminum Frames

Caution
Product Description
The pre-assembly insertion nut is installed from the flange of the groove before assembly. Large width causes less allowance in the groove for bolting easily.

Specifications Overview of Nuts
■For pack Nuts sales (1 pack contains 100 pieces)
■ Anti-loosening Nuts type
- This Nuts has a loosening prevention agent applied to the inside of the tap. This reduces loosening caused by vibrations during transportation or equipment operation.
- What is a loosening prevention adhesive? It is an anaerobic adhesive encapsulated in microcapsules. It effectively prevents loosening, but please note that it requires a hardening time (72 hours at room temperature 25°C) and that it isno longer effective once loosened.
- Resin coating is a coating of resin that conforms to the shape of the Nuts. Although it does not have the same locking effect as adhesive types, it can be used repeatedly without requiring hardening time.
■Effects of anti-loosening Nuts agents (reference values)
| Features of Nuts | Release torque after tightening (1st time) | Supplementary information | |||
|---|---|---|---|---|---|
| No anti-fouling agent applied | - | 5.2N・m | - | ||
| Anti-loosening for Nuts adhesive Nuts type | ・Effectively prevents for Nuts loosening ・However, once loosened, the effect is lost ・After tightening, the adhesive needs time to harden (approximately 72 hours at room temperature 25℃) | 7.6N・m | Test conditions Nuts: Tightened to 6.8 Nm, dried at room temperature (25°C) for 72 hours, then loosened the bolts. Measured with HNTTV5-5 | ||
| Anti-loosening for Nuts resin coated Nuts type | - The anti-loosening effect can be used repeatedly (the anti-loosening effect will decrease with repeated use) - The anti-loosening Nuts effect is immediate after fastening | 6.5N・m | ・The loosening prevention effect decreases with repeated use. ・5th return torque: 6.2N・m (measured with HNTTZ5-5) | ||
[ ! ] The torque values are for reference only. The values may vary depending on the clearance between the bolt and Nuts.
■ What is conductive function?
- The conductive Nuts has a protrusion.
- When installed, the protrusions peel off the anodized coating on the aluminum frame, making it conductive.

How to Use of Nuts
This product is a pre-insertion Nuts. Please insert it into the aluminum frame before use.
Selection Support Information for Nuts
■ Difference between first-in and last-in
・MISUMI aluminum frame Nuts are available in a variety of types, including first-in and last-in. Use them according to your needs.
First-in: Install from the groove end face before assembly. They are wide and have little play inside the groove, making Nuts tightening easy.
Post-insertion: The Nuts Can be installed through the groove after assembly.
■ If the aluminum frame becomes stuck and cannot be removed
To remove the Nuts, hook the hex wrench into the hole in the nut and turn it at right angles to the groove.
■ Measures to prevent Nuts from falling
・If the Nuts fall off when the aluminum frame is placed vertically, it is effective to use a temporary stopper (with a spring and plastic non-slip).
・If using Nuts without a temporary stopper, attach a pre-insertion stopper before inserting them into the groove.
