Applicable scope and quality requirements for aluminum iron CSK head rivets

- Nov 27, 2018-

Aluminium iron CSK head rivets are parts that are riveted in their riveting using their own deformation or interference. It is not only suitable for occasions where the strength requirement is not high, the thread diameter is less than 10MM, the screw is screwed in and tightened, and at the same time, since the screw head is completely or partially sunk into the connected piece, this structure is mostly used for the flat and smooth appearance, such as the instrument table. Therefore, it is widely used in automobiles, vehicles, mechanical and electrical products, building decoration and household appliances.

According to the relevant regulations, the test methods for the mechanical properties of the aluminum iron CSK head rivets include shearing, resistance, nail head retaining ability, nail core removal force and core breakage. A total of 5 tests are also carried out. The rivets can also be riveted according to the requirements of use. And shear strength test. The state that needs to be achieved is that the surface of the aluminum-iron countersunk rivet is not allowed to have cracks affecting the use; the top surface of the nail head is not allowed to have small metal protrusions that affect the use; the blunt, flash, bump, and strips that do not affect the use are not allowed. The mark, the floating rust and the flattening of the end of the rod have high requirements on the coaxiality tolerance of the rivet rod.

Aluminum iron CSK head rivets are well used, and in any product assembly, where the gaps are extremely limited, the protrusions of the rivet body must be minimized or eliminated from the surface of the application. Due to the PT rivet sleeve, the shaft head and the mandrel remain assembled as a whole to ensure that there are no loose mandrel heads. It is widely used in the storage equipment of the electronics industry, but it is also suitable for many low gaps. These features and advantages are unique in the market.
