Stainless Steel CSK Head Closed End Blind Rivets
Product Overview
CSK Head Closed End Blind Rivets are widely used fastening components designed for precision joining of materials when access is only available from one side of the workpiece. Manufactured according to ISO 15974 standards, these rivets feature a countersunk (CSK) head which allows a flush surface finish, and a closed-end design which provides excellent sealing and prevents leakages. The use of premium-grade stainless steel ensures resistance to corrosion, making them ideal for applications in demanding environments, such as marine, automotive, and industrial manufacturing.
These rivets are especially beneficial where sealing and strength are crucial. The closed-end design ensures that no moisture or contaminants infiltrate the assembly, thereby increasing durability and life span of the joint.

Material & Manufacturing Process
These rivets are crafted from high-grade stainless steel, typically type A2 (304) or A4 (316) according to application demands. The selected material offers a remarkable combination of strength and corrosion resistance, making it suitable for outdoor and harsh environments.
Manufacturing involves high-precision cold forging, thread rolling, and head forming. The CSK head structure is carefully shaped to ensure flush mounting. The closed-end is formed by precisely sealing the tail end to completely block penetration of liquids or gases — a vital feature for aerospace and industrial cases. Surface finish options include natural stainless steel polish or enhanced passivation for improved corrosion resistance.
Typical Applications & Industries
CSK Head Closed End Blind Rivets are trusted in multiple industries and application scenarios:
- Automotive manufacturing: used in engine compartments and underbody components
- Aerospace & Aviation: provides sealed fastening in lightweight composite panels
- Marine applications: ideal for joining corrosive-exposed components
- HVAC systems: used for leakproof fastening of air ducts
- Electronics: seals enclosures to protect components
- Furniture and appliances: ensures aesthetic finish and structural integrity
