Ball Lock Bolts, Fit 5/8 Holes

An essential time-saving fastener. All Ball Lock Bolts are a time-saving and efficient method of locating and fastening fixture elements to the tabletop without having to reach underneath the table. Insert the Ball Lock Bolt over the fixturing element and turn the knurled head with your hand for initial positioning. The Ball Lock Bolt consists of three locking steel balls in the bolt shank that move outward to lock against the bottom chamfer of the table plate, pulling the fixture components securely downward and tightening them in place. Once all the Bolts are positioned, tighten the socket head cap screw top of the Bolts with a light turn of a hex wrench. Ball Lock Bolts release quickly from the Bolt top with a turn of your hex wrench. The Universal Ball Lock Bolt T55057 features an adjustable sliding shoulder bushing, providing better surface contact while also reducing friction when torquing down screws. Please note that T55015 is not compatible with Alpha 5/8 tables.
