COMPRESSION BOLT

“Compression bolt” for exclusive use of through nut (long type) is a product in which a steel ball and a spring are built in an aluminum bolt, and it is a product to be attached to the excess screw part of the through nut that was actually attached (see the figure below). You can create an appearance that looks like you are wearing a super long hub bolt !!
Moreover, the tension of the spring improves the loosening prevention effect of the attached nut.
