JKB double-notch toothed t-bolts have double serrations on the underside of the screw head. When tightened, they press into the channel lips of the smooth, hot-rolled anchor or mounting channels to create an interlocking and non-slip connection. This transmits forces when anchoring loads in the longitudinal direction of the channel. They are available in various thread diameters and lengths. JKB double-notch toothed t-bolts have two notches at the end of their shaft to identify the bolt's position.
