( Brand: Cherrymax ), ( Manufacturer Part Number: M7885/7-4-2 )
The Cherrymax M7885/7-4-2 blind rivets from Cherry Aerospace are a versatile and reliable solution for fastening applications in various industries, including aerospace, automotive, and construction. These blind rivets are designed to provide a strong, permanent bond between two materials without the need for additional nuts or washers.
Each M7885/7-4-2 blind rivet measures 7/16 inch in length and has a diameter of 0.042 inches. The rivet head is domed, with a diameter of 0.110 inches, allowing for a flush or semi-flush finish when installed. The shank of the rivet is swaged to form a tapered, self-drilling point, enabling the rivet to easily penetrate and form a secure bond with the material.
These blind rivets are made from high-strength, low-alloy steel, ensuring a high tensile strength and ultimate load capacity. The steel is also coated with a protective zinc coating to prevent corrosion and ensure longevity in harsh environments.
The installation process for the M7885/7-4-2 blind rivets is simple and efficient. The rivet is loaded into a pneumatic or hydraulic gun, which applies the necessary force to drive the rivet through the materials being joined. Once the rivet has penetrated both materials, the gun delivers a final blow to swage the rivet head and form the permanent bond.
Overall, the Cherrymax M7885/7-4-2 blind rivets offer a strong, reliable, and cost-effective solution for a wide range of fastening applications. Their versatility, combined with their high strength and corrosion resistance, make them an ideal choice for industries where reliability and durability are essential.
Cherrymax M7885/7-4-2 blind rivets, also known as Cherry Aerospace blind rivets, are a popular choice for assembling various structures, especially in the aerospace industry. Here are some pros and cons of using these blind rivets for your assembly projects:
Pros:1. High Shear Strength: These blind rivets offer a high shear strength, making them suitable for assembling structures that require strong bonds between the parts.
2. Self-Threading Capability: The self-threading feature of these blind rivets eliminates the need for pre-drilling or tapping, which can save time and reduce the risk of errors.
3. Versatile: Cherrymax M7885/7-4-2 blind rivets come in various sizes and materials, allowing users to choose the right one for their specific application.
4. Rivet Head Holds: The rivet head holds firmly once the rivet is set, ensuring that the parts remain in place even under heavy loads.
Cons:1. Limited Pull-Through Length: The pull-through length of these blind rivets is limited, which means they may not be suitable for assembling structures where the parts are far apart.
2. Requires Special Tool: Setting these blind rivets requires a special tool, which can add to the overall cost of the project.
3. May Not Be Suitable for Thin Materials: The minimum material thickness for using these blind rivets is 0.06 inches, which may not be suitable for assembling structures made of thin materials.
Conclusion:Cherrymax M7885/7-4-2 blind rivets offer high shear strength, self-threading capability, and versatility, making them a popular choice for assembling structures, particularly in the aerospace industry. However, their limited pull-through length and the requirement for a special tool may add to the overall cost and complexity of the project. Therefore, it is essential to consider the specific requirements of your project and weigh the pros and cons before deciding to use these blind rivets.
Recommendation:If you are assembling structures with heavy loads and the parts are close enough, Cherrymax M7885/7-4-2 blind rivets can be an excellent choice due to their high shear strength and self-threading capability. However, if you are working with thin materials or parts that are far apart, you may want to consider other types of fasteners, such as screws or bolts, that may be more suitable for your application.
