S-92015A204 M4 x 30 mm DIN 916, ISO 4029 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and long-term reliability.
• Secure, flush mounting thanks to the headless design, preventing interference in compact assemblies.
• High torque application capability via the 2 mm hex drive, ensuring tight, reliable fastening without slippage.
• Quick and easy installation with the coarse (0.7 mm pitch) right-hand thread, reducing assembly time.
• Precise thread engagement and consistent performance guaranteed by Class 6g thread fit tolerance.
• Firm gripping action from the cup tip, which digs into surfaces to prevent component loosening under vibration.
• Compliance with major environmental and safety standards including RoHS 3 and REACH, ensuring safe use in regulated industries.

Professional Applications & Engineering Value

This M4 hex headless set screw is engineered to address critical challenges in precision assemblies where space is limited and vibration resistance is paramount. Manufactured from 18-8 stainless steel, it offers excellent resistance to rust and corrosion, making it suitable for applications in machinery, automotive, and electronics exposed to moisture or chemicals. The headless design allows for flush installation, eliminating protrusions that could interfere with moving parts or aesthetic requirements. Combined with a coarse metric thread (0.7 mm pitch) and right-hand thread direction, it ensures rapid installation and high clamping force, reducing the risk of loosening in dynamic environments. The cup tip provides enhanced grip on shafts or components, ideal for securing gears, pulleys, and collars securely. Adherence to DIN 916 and ISO 4029 standards guarantees dimensional accuracy and interoperability, delivering consistent performance in B2B and industrial fastener applications.
