Products Description

The Slotted Step Rivet is a type of fastener integrating drilling, tapping and fastening functions in one. Its structural feature lies in a special slotted design on the rivet head, which ensures stronger adaptability and higher installation flexibility during operation. The stepped tail structure can effectively penetrate metal materials and gradually expand to firmly fix the materials when tension is applied, thus guaranteeing stable connections. Suitable for various metal materials including steel plates, aluminum alloys and copper plates, the Flat Head Step Rivet enables direct installation without pre-drilling. It eliminates the cumbersome procedures of traditional fastening methods, significantly shortening assembly cycles and reducing labor costs.

Product Advantages

Efficient Installation

The Step Flat Head Rivet features a self-drilling design that enables direct drilling, tapping and fastening on the material surface in one go. Eliminating the need for an extra pre-drilling step, it significantly saves time and labor costs, making it ideal for large-scale production lines. Its unique self-drilling tip acts like a precision micro drill bit, which can quickly penetrate the material surface upon contact. Combined with the built-in spiral tap structure, it completes the tapping process synchronously. The entire installation operation is seamless and can be finished with simple tools, greatly lowering the skill requirements for operators.

Wide Applicability

The Slotted Head Step Rivet is compatible with metal materials of varying thicknesses, from thin sheets to heavy plates, as well as different metal types. Its strong adaptability allows for broad application across diverse industries. Whether applied to lightweight aluminum alloy panels, heavy steel plate structures, cold-rolled steel or stainless steel, this rivet delivers superior performance. It has become the ideal choice for joining metal sheets of different specifications, especially in fields like automotive manufacturing, home appliance assembly, building decoration and machinery processing.

High-Strength Connection

Boasting a stepped riveting design, the Slotted Flat Head Step Rivet can firmly lock metal sheets in place, preventing loosening and falling-off issues. Its connection stability far exceeds that of traditional bolts and welding methods. During the riveting process, the stepped structure generates greater clamping force, bringing the joined sheets into tight contact. This effectively resists stress caused by vibration and impact, ensuring long-term stability of the connection area and avoiding common problems like loosening, cracking or corrosion that plague conventional connection methods.

Enhanced Production Efficiency

Integrating drilling, tapping and fastening functions into one, the Flat Head Step Blind Rivet greatly improves installation efficiency, making it particularly suitable for high-efficiency, high-volume production environments. When paired with special riveting equipment in automated production lines, it can achieve an installation frequency of dozens or even hundreds of times per minute. This not only significantly shortens product assembly cycles and reduces production costs, but also ensures consistent connection quality, providing strong support for the efficient production of modern industry.

Production Process

Cold Heading Forming: The Flat Head Step Break-Stem Rivet's shape, dimensions and strength are optimized through precision cold heading, a metal plastic working process. At room temperature, the metal material undergoes plastic deformation under intense pressure and is gradually formed into the required head shape and shank structure of the Flat Head Step Structural Rivet through multi-pass die stamping. This process not only improves material utilization but also densifies the internal structure of the rivet, significantly enhancing its tensile strength and fatigue resistance to ensure reliability across various connection scenarios.

Precision Drilling: This step ensures the accurate positioning of the drill hole on each Slotted Head Step Break-Stem Blind Rivet for smooth installation operations. High-precision CNC drilling machines or dedicated drilling equipment are adopted to drill the rivet shank in strict accordance with design specifications, with the hole diameter error controlled within the micron range. The drilled surface is smooth and burr-free, which guarantees seamless compatibility between the Slotted Step Break-Stem Rivet and the riveting gun during installation, and avoids installation difficulties or connection failure caused by hole misalignment or rough hole walls.

Surface Treatment: To enhance the corrosion resistance of the Flat Head Step Rivet with Slotted Drive, we offer a range of surface treatment processes including galvanizing, chromium plating and passivation, tailored to meet application requirements in different environments. Galvanizing effectively isolates the metal substrate from air and moisture to prevent rusting. Chromium plating endows the surface of the Step Flat Head Rivet with higher hardness and glossiness, along with excellent wear resistance and corrosion resistance, making it suitable for harsh environments such as humid, acidic and alkaline conditions. Passivation treatment boosts the oxidation resistance of the rivet at a relatively low cost, which is ideal for applications in general indoor or dry environments.

Application Advantages

1. Construction and Steel Structures

During the installation of steel structures, especially for fixing components such as curtain walls, skylights, doors and windows, Slotted Head Step Rivets can effectively improve installation efficiency while ensuring connection stability. Meanwhile, the rivets achieve joining based on the cold extrusion principle, forming a tight metal bonding surface that can withstand high shear and tensile forces. This effectively avoids the loosening issue that may occur with traditional bolted connections, thus guaranteeing the overall stability and safety of the building structure.

2. Automobile Manufacturing

In the automotive production process, particularly for splicing thin body steel plates and connecting vehicle bodies, Slotted Flat Head Step Rivets can enhance connection strength, reduce the use of traditional bolts and welding, and lower production costs. Compared with welding, Flat Head Step Blind Rivet connections will not cause thermal deformation, maintaining the original precision and strength of body panels. In contrast to bolts, the installation process is simpler and faster, eliminating complex steps such as tapping and tightening, which can significantly improve assembly efficiency.

3. Photovoltaic Supports

In photovoltaic systems, Flat Head Step Break-Stem Rivets are commonly used for fixing solar supports, providing stable and firm connections to ensure the long-term reliability of the system under harsh environments. Photovoltaic supports need to withstand long-term exposure to sunlight, wind and rain erosion, temperature changes, snow loads and other external forces. Thanks to their excellent corrosion resistance and high-strength characteristics, Flat Head Step Structural Rivets can effectively resist the impact of these environmental factors and maintain the structural stability of the supports.

4. Home Appliances and Furniture

In the production of home appliances and furniture, Slotted Step Rivets can improve assembly efficiency, ensure the firmness of connected components, and extend the service life of products. Home appliances such as refrigerators, washing machines, air conditioners, as well as furniture including wardrobes, bookcases, tables and chairs, require a large number of plate splicing and frame assembly processes during production. Slotted Head Step Break-Stem Blind Rivets feature convenient installation, enabling quick component fixation and improving the operational efficiency of the production line.
