■ 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 Nuts and turn it at right angles to the groove.
