Using the HELO 6mm Square Head Axle Upgrade Kit W/Bolt Glue means you won't have to deal with stripped out or never staying tight axles again. This kit replaces the axles of your preexisting chassis for added strength and reduced tightening.

Please note that with some skate / chassis models the axle with the square end may be a tight fit initially upon installation. Hand tighten fully with a bit of torque to get the square end to pull into the chassis. After having done this a few times, the square head should go in and come out without much effort.
