Designed for precision and reliability, the BuildPro® Ball Lock Bolts from Strong Hand Tools are essential for securely connecting two fixturing elements. With a capacity of 1.1 inches and a convenient 1/4-inch wrench size, these bolts feature a unique mechanism where turning the knurled head activates three locking steel balls that expand outward, locking firmly against the chamfer of the fixturing element. This innovative design ensures a robust and stable connection, making them an ideal choice for any serious fabrication or assembly project.
