Assortment of 150 Round Tip Ball End Spring Bars an assortment of 150 pieces (10 each of 15 sizes) of stainless steel ball-end single flange spring bars – body diameter 1.60mm. All mm sizes from 8 to 22 mm. These pins are typically used on buckles with folding safety catch, so that the safety catch can easily push over the ball ends of the protruding spring bar without catching (unlike a typical square tip spring bar!)
