Products Description
Grade12.9 Alloy Steel Button Head Hex Drive Screws are mostly used after installation, the surface of the parts can
not be raised, and the fastened parts have two thicknesses, the
so-called thick, which means that the thickness of the fastened
part is greater than the thickness of the head of the countersunk
screw Thickness. After the screw is tightened, there is still a
part of the screw thread that does not enter the threaded hole. In
this case, the countersunk screw can definitely be tightened. There
is usually another case, that is, the thickness of the fastened
parts is less than the height of the head of the countersunk head
screw, which is common in sheet metal parts in mechanical
equipment, such as the connection of the hinge of the chassis and
the door and the box; the sheet metal of the equipment The
connection between the cover and the equipment, etc. Due to the
small thickness of the part, the screw through hole of the fastened
sheet metal part has become a conical hole completely. In this
case, when the countersunk screw is tightened, the screw head is
not a conical surface to compress the sheet metal part. , But the
bottom of the screw head and the top of the threaded hole are
squeezed. Although the screw feels that the screw is tightened, the
sheet metal part is stuck instead of being pressed. In this case,
although the screw feels that the screw is tightened, the sheet
metal The gold piece is indeed not tightened. This is a very common
situation.
