Flange surface bolts are common fasteners. Flange surface bolts are widely used in highways and railway bridges, including heavy machinery such as industrial and civil buildings, cranes, excavators, etc., and are widely used. Today we will briefly introduce the basic classification of flange bolts. Basic classification of flange bolts.
Hex head bolts with holes will create an open pin hole on the bolt's screw. You can use a wire to pass through the wire hole, which will help easier tightening, mechanical loosening and prevent loosening reliably? Hexagon head hinge hole bolts, bolts with hinge holes can better fix the mutual position of the connecting parts, and can withstand transverse shearing and squeezing.
Cross recessed hexagon head bolts are easy to install. They are mainly used for light industry and light load instruments. For square-head bolts, the size of the head is large, and the bearing surface of the bolt is also large. This is convenient for the wrench to jam the head, and the tightening method is very convenient, or other parts are used to stop rotation. The square neck of the countersunk bolt has the function of stopping rotation.
It is usually used in the occasions where the surface of the connecting parts is required to be flat or smooth. T-slot bolts are suitable for connecting bolts where they can only be connected from the side. After inserting the bolt from the T-slot and rotating it 90 degrees, the bolt cannot be loosened; it can also be used in places where compact structure is required. Anchor bolts are dedicated to embedded concrete foundations and used to fix the base of machines and equipment.
