S-92029A144 M4 x 8 mm DIN 916, ISO 4029 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments due to 316 stainless steel construction, ideal for marine, chemical, and outdoor applications.
• Exceptional mechanical strength and durability with a Rockwell B80 hardness, ensuring reliable, long-term fastening under stress.
• Secure, non-slip installation with the 2 mm hex drive, providing high torque transfer and reducing the risk of tool slippage.
• Enhanced grip and anti-loosening performance from the cup point tip, which bites into the contact surface for a vibration-resistant hold.
• Precise and reliable thread engagement with Class 6g coarse threads (M4 x 0.7mm), facilitating quick assembly and reducing cross-threading risks.
• Compliance with international quality standards including DIN 916/ISO 4029, ensuring dimensional accuracy and interchangeability.
• Safe for regulated industries as it is RoHS 3 and REACH compliant, meeting strict environmental and health safety requirements.

Professional Applications & Engineering Value

This M4 set screw is engineered to address critical challenges in industrial settings where vibration, moisture, and corrosive agents threaten fastener integrity. The 316 stainless steel material offers excellent resistance to pitting and crevice corrosion, making it suitable for demanding applications in marine equipment, chemical processing, and food machinery. The headless design and hex drive allow for flush mounting in confined spaces, while the cup point provides superior biting action to prevent loosening under dynamic loads. With its coarse thread and Class 6g tolerance, it ensures quick, secure installation in soft metals or plastics, reducing assembly time and maintenance costs in industrial fastening systems.

Specification Summary & Compliance
