I produced the self-washed rivets, in accordance with its geometry and size of the different, is divided into five series. Each series is divided into many different types according to their different materials, rivet head form, nail bar diameter and length, to fully meet the user's process requirements and application needs.
The selection of optimum rivets for a given riveting process requires consideration of a large number of process parameters and process details. See "Riveting Parameters Study and Test" for details. After selecting the rivets should also be accompanied by suitable for customers in the actual application of riveting equipment. Rivets generally need to consider the following points:
Rivet head form
|Typical application characteristics
|Type of plate
||Aluminum plate, steel plate, plastic plate or composite material
|Lower hardness material
||Cold rolled steel sheet or aluminum sheet
|Medium hardness material
||Hot rolled steel sheet, extruded sheet or cast sheet
|Low elongation material
||Medium carbon steel, non-ferrous alloy or plastic plate
|High elongation material
||HSLA steel or DP & TRIP steel
|Total Thickness of Sheet Group
1mm to 6mm (steel)
1mm to 10mm (steel)
|Composite material riveting
||Plastic + metal, aluminum + steel
|Non - structural
||Furniture, cabinets, accessories and so on
The choice of rivet head form is generally based on the requirements of the performance of riveting or aesthetic considerations, the performance requirements of the riveting:
Countersunk head rivets
- - The flatness of the workpiece after riveting (whether the head of the rivet and the sheet metal);
- - Shear, peel and fatigue strength test;
- - Marking position or for mechanical stop;
- - A very large surface;
- - Subsequent process needs.
Flat head rivets, head rivets and ball head rivets
- - Riveted joint head side is very smooth;
- - High fatigue strength.
Special rivet head form
- - Provides a great tightening force, especially for plastic plates or thinner metal plates;
- - To ensure that the rivet head positioning, especially for thicker or harder plate;
- - Highlighting the aesthetics of the rivet joint or covering the recesses of the root of the rivet.
When the need to self-pierce riveting and other processes used in combination, we need to consider the use of special rivet head form.

Rivet length and nail bar diameter
The length of the rivet needs to be considered in connection with the thickness of the riveted plate set. A certain length of the rivet can cover a certain range of plate thicknesses. The optimum length of the rivet can be determined experimentally for the hardness and thickness of the riveted plate set. Companies can provide a variety of rivets from 4 mm to 14 mm in length.
Rivet diameter of 3 mm and 5 mm two kinds of specifications, select the appropriate diameter of the rivet is the standard:
- - Fastening force required for riveting;
- - The durability required for riveting;
- - Spatial constraints;
- - Thickness and hardness of the sheet.
The surface treatment of rivet is a basic aspect of self piercing riveting process. In the purchase of rivets, customers need to carefully confirm the relevant technical requirements.
In the process of Rivet processing, the surface treatment process, on the one hand, provides an anti rust protection for self piercing rivet, in addition, it can also meet the requirements of some users. Standard rivet coating and coating in the following table, mainly for the protection of steel rivets, for the riveting of steel plate and aluminum plate:
||Typical riveting applications
||Mainly used for coating, coating of steel riveting
||Mainly used for aluminum riveting, temperature up to 180 ° C
||Mainly used for aluminum riveting, temperature up to 165 ° C
(Covered with zinc plating)
|Silver or black
- Food-grade coating
- Decorative purposes
|Rivet head end spray
(Covered on other normal coatings)
|A variety of colors to choose from
||For the same color as the riveted sheet set.
||Mainly used for stainless steel rivets, improve the decorative, or for rust.
|High thermal insulation coating
||Please contact our company for further details.
In order to meet the increasingly wide range of riveting applications, and the increasingly stringent customer requirements for environmental protection, the company continues to develop new coatings and coatings for rivets in its own laboratories. In fact, many of these R & D projects are carried out jointly with customers of.
Standard rivets are made of special grade steel wire as raw materials, through forging, hardening and tempering processes. In a very wide range of applications can provide the best riveting performance.
- - Austenitic stainless steel rivets - used to rivet the hardness of stainless steel sheet;
- - Martensitic stainless steel rivets - for riveting stainless steel rivets can not be connected with austenitic stainless steel plate of high hardness;
- - Copper rivets - for riveting special plates such as copper, brass and plastic sheets; li>
- - Aluminum rivets - used to rivet the aluminum sheet with low hardness.
The rivets are manufactured at different hardness levels to meet the requirements for riveted riveted panels. In general, the hardness of the rivet increases as the thickness and / or hardness of the riveted plate increases. Customers can contact the company at any time to determine the applicable rivet hardness and shape.
Manufacturing & Quality:
The company's production center is equipped with the world's most advanced production line of rivets, each production line has a steel wire to reverse, straightening, SPC control of multi-die forging and other special equipment, rivet manufacturing after automatic optical inspection system after inspection, Packaging factory.
Advance R & D allows the company to provide customers with the widest range of rivets varieties and related products, such as self-piercing riveting bolts, T-type self-piercing pin and self-piercing riveting pins and other special self-washed products. R & D results to promote the introduction of a new type of rivets, rivets also have steel, stainless steel, aluminum, copper and brass and other different materials to choose from.
Since the design of rivets from scratch, the manufacturing process from raw material processing to finished products throughout the entire process, both through the SGS international tripartite certification and intellectual property certification.
Rivets are fixed to the rivet belt, and then sub-installed as a box or disk factory. Rivet boxes are made of plastic, typically containing 200-800 pieces of rivets per box. Riveted rivets provide maximum freedom of movement and flipping for rivet guns and are typically used for manually operated riveting systems. Plate rivets generally can be split per plate 4000-10000 rivets, both for manual operation of the riveting system can also be used for automatic or robot operation of the riveting system. Rivets in plastic can be reused, and the center slot can be made into a special shape, allowing a particular type of rivet to be mounted only on a riveted device, provided the customer uses a variety of rivets.
