When purchasing rivets, you need to pay attention to the following key points to ensure that the selected rivets can meet the needs of use, and have good quality and performance.
First, clear use requirements
Application scenario: First of all, it is necessary to clarify what occasions the rivets will be used for, such as construction, automobiles, ships, furniture manufacturing, etc., different occasions may have different requirements for rivets.
Connector material: Understand the material to be connected, select the matching rivet material to prevent electrochemical corrosion and ensure the strength of the connection.
Second, choose the right material
Stainless steel rivets: have good corrosion resistance and high temperature resistance, suitable for humid environment and high temperature environment. Stainless steel rivets have a variety of materials, such as 304, 316 and 316L, etc., should be selected according to the use of the environment.
Carbon steel rivets: with high strength and hardness, suitable for heavy duty and high strength connection occasions. Usually after galvanized or black oxidation surface treatment in order to increase corrosion resistance.
Copper rivets: with good electrical and thermal conductivity, suitable for electronic and electrical fields. Copper rivets look beautiful, but the cost is higher.
Aluminum rivets: light and corrosion resistant, suitable for lightweight occasions. But the hardness is small, suitable for low strength connection occasions.
Third, pay attention to the specifications of rivets
Diameter and length: The diameter determines the carrying capacity of the rivet, while the length affects the appearance and strength after riveting. The rivet length should be determined according to the total thickness of the connected part, and ensure that the end face of the rivet after connection is flush with the rivet or the sag does not exceed the allowable range.
Head shape: According to the use of the needs to choose the appropriate head shape, such as flat head, half round head, heavy and so on. Different head shapes are suitable for different riveting occasions and surface requirements.
Fourth, check appearance and quality
Appearance inspection: high-quality rivets should be smooth, no burrs, no rust and other defects. At the same time, attention should be paid to whether the shape and size of the rivet head are consistent, and whether the threaded part is clearly visible.
Identification information: Qualified stainless steel rivets should have clear product identification, including material, specifications, production date and other information. This helps to ensure the legality and traceability of products.
Fifth, consider brand and price
Brand choice: Products from well-known brands are more guaranteed in terms of quality and service, but the price may be relatively high. Consumers should make reasonable choices according to their own needs and budgets.
Price comparison: There are many brands of stainless steel rivets on the market, and the prices are uneven. In the purchase should be a comprehensive consideration of price, quality and after-sales service and other factors, to avoid blindly pursuing low prices and ignoring product quality.
Sixth, other precautions
Operation convenience: According to the characteristics of the riveting operation to choose the right type of rivet, such as double-sided operation can choose solid rivet, unilateral operation space is small can choose flowering rivet and so on.
Environmental requirements: In some cases, it may be necessary to consider the environmental performance of rivets, such as whether they contain harmful substances.
To sum up, the choose and buy when rivet need to make a comprehensive consideration, from several aspects to ensure the selection can satisfy the using demand of rivet and have good quality and performance.
