Stainless Steel 304 316 Slotted Countersunk Mushroom Head Bolt
Countersunk head screws mostly used in the need to install a raised surface of the part can not place the fastening parts there are two kinds of thickness, the so-called thick, that is fastened to the parts is greater than the thickness of the head of the countersunk head screw thickness after tightening the screw, there is no part of the screw threaded into the threaded hole. This situation, certainly countersunk head screws tightened. Typically there is a situation that is fastened to the part thickness smaller than the height countersunk screw head, which is common in sheet metal parts in machinery and equipment, such as a hinge and the cabinet doors and the coupling of the chassis; sheet metal equipment housing and coupling devices and so on. Due to the small thickness of the part, are fastened sheet metal parts, screws vias completely into a conical bore, in this case, when the countersunk screw is tightened, the screw head is not pressed sheet metal cone , but the top of the screw head and a threaded hole at the bottom of the root Jisi, although the feeling screw is tightened, but the sheet metal is pressed instead of being stuck in this situation, although feeling tighten the screws, but the sheet metal parts really have not been tightened. This is a very common situation.
To tell you the reason for working on: countersunk screw head round vertebrae was 90 ° cone angle, usually bought a new drill apex angle was 118 ° -120 °, the lack of training of some of the workers do not know the angle difference, one often the direct use of reaming drill 120 °, which resulted in not Shen head screws tighten head conical surface difficult, but the bottom line of the screw head is difficult, which is the so-called head screws tight could not reason .
