Featuring a smooth, low-profile domed head and a square collar beneath, these bolts pull directly into softwoods or hardwoods as the nut is torqued. This anti-rotation square neck locks the bolt securely in place, allowing single-person installation using only a single spanner or wrench on the hexagon nut side.
This bolt has a square shoulder under a rounded head (Mushroom Head) which resists turning when the nut is tightened or removed. The bolt is driven into a hole the same size as the shank and then hammered the rest of the way, where the square shoulder locks firmly into place.
