Outer hexagon bolt with large contact area

Outer hexagon bolt with large contact area The outer hex screw, also known as the hex head bolt, has a hexagonal head and is used for installation and removal. This design gives the outer hex screw a significant advantage in terms of bearing capacity and durability. The threads on the outer hexagonal bolts are generally mainly used on thin-walled parts or under impact, vibration or alternating loads. Generally, the outer hexagonal bolts are made of partial threads, and the full-thread outer hexagonal bolts are mainly used for the nominal length of the outer hexagonal warp and the occasions requiring longer threads. External hexagon bolts with holes are used when external hexagon bolts are required to lock. The outer hexagon bolt with hinged holes can accurately fix the phase to position of the connected parts. And can be subjected to shear and extrusion caused by mold forces. The advantage of the outer hexagon is that the pre-loaded contact area is large, and a large pre-loaded fo…
