DIN660 Round Head Rivets
DIN 660 Round Head Rivets are solid rivets with a characteristic round head and cylindrical shank, designed for permanent fastening of metal components. Manufactured according to DIN 660, these rivets are installed by deforming the unheaded end of the shank to form a secure mechanical joint. The round head provides a stable bearing surface while maintaining a simple and traditional riveted joint design.
DIN 660 rivets can be supplied in different diameters and lengths to suit various material thicknesses and assembly requirements. Common material options include carbon steel and stainless steel, with material selection based on the required strength, corrosion resistance and forming performance. We can supply DIN 660 Round Head Rivets in different specifications and quantities according to your application and project requirements.


Specification:
The specification of DIN 660 Round Head Rivets is mainly defined by the rivet diameter, shank length, head geometry, and material used for permanent joining. Unlike threaded fasteners, the rivet is selected according to the hole diameter and the total thickness of the components being joined. The round head provides a defined bearing surface on the exposed side, while the cylindrical shank is formed at the opposite end during riveting.
DIN 660 rivets can be supplied in different diameters and lengths to match the thickness of the assembled parts. Common material options include low-carbon steel, stainless steel, aluminum, and copper, depending on the required strength, corrosion resistance, conductivity, and forming characteristics. Plain, zinc-plated, or other surface conditions can be specified according to the rivet material and application requirements. Key dimensional parameters include nominal diameter, rivet length, head diameter, head height, and shank dimensions.

Dimension Chart of DIN660 Round Head Rivets:
The DIN 660 dimension chart provides the measurements needed to select a round head rivet for a permanent joint. The nominal diameter determines the required hole size, while the rivet length is selected according to the combined thickness of the parts being joined and the material required to form the closing head. Head diameter and head height define the bearing area of the finished rivet head, while the shank dimensions determine how the rivet fits through the joint before riveting.
For each DIN 660 size, the chart can be used to compare the nominal diameter (d), rivet length (l), head diameter (dk), head height (k), and shank dimensions. Selecting the correct length is particularly important because insufficient material may result in an improperly formed closing head, while excessive length can create unnecessary deformation during riveting.

Application of DIN660 Round Head Rivets:
DIN 660 Round Head Rivets are selected in different diameters according to the thickness of the parts being joined and the load carried by the permanent joint. Smaller sizes around Ø1 mm to Ø3 mm are suitable for light-duty assemblies such as instrument panels, small electrical components, switches, meters, and compact sheet-metal parts. Ø4 mm to Ø5 mm rivets provide a larger joint area for equipment housings, ventilation components, electrical cabinets, appliance frames, and general sheet-metal assemblies, while Ø6 mm to Ø8 mm sizes are more commonly considered for heavier joints such as machinery frames, agricultural equipment, metal brackets, structural sheet-metal components, and fabricated equipment.
Material selection depends on both the mechanical requirements and the surrounding environment. Steel DIN 660 rivets are suitable for general mechanical fabrication and equipment assembly where a permanent joint with good mechanical strength is required. Stainless steel versions are preferable for food-processing equipment, outdoor machinery, marine components, and other assemblies exposed to moisture or corrosive conditions. Aluminum rivets can be selected where low weight and easy forming are important, such as lightweight equipment housings and electrical enclosures, while copper versions are useful in assemblies where electrical conductivity and corrosion resistance are required.
