■ Anti-loosening for Nuts type

5 Series (groove width 6 mm) Pre-insertion nuts for 20, 25, and 40 square aluminum frames Related image 1_Specifications and overview

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 itis no 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.

[ ! ] 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.

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 bolt 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 temporary stoppers (with springs and plastic non-slip pads).
When using a Nuts that does not have a temporary locking function, attach a pre-insertion stopper before inserting it into the groove.
