S-91217A110 M4 x 5 mm DIN 914, ISO 4027 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, non-slip fastening provided by the 90° cone point, which bites into surfaces to prevent component movement.
• High-strength durability backed by Rockwell B80 hardness, ensuring the screw withstands applied torque and resists wear.
• Efficient installation and removal with the 2 mm hex drive, allowing for high torque application in confined spaces.
• Reliable thread engagement due to the Class 6g thread fit and coarse M4 x 0.7mm pitch, enabling quick assembly and vibration resistance.
• Space-saving headless design that sits flush with or below the surface, perfect for compact assemblies.
• Global compliance and safety with adherence to DIN 914/ISO 4027 standards and RoHS 3 & REACH environmental regulations.

Professional Applications & Engineering Value

This M4 set screw is engineered to address critical industrial fastening challenges, particularly where space is limited and vibration resistance is paramount. The headless design and cone point work in tandem to provide a flush, secure fit that prevents loosening under dynamic loads, making it ideal for securing gears, pulleys, and collars on shafts. Manufactured from 18-8 Stainless Steel, it offers excellent resistance to corrosion and oxidation, ensuring longevity in demanding environments such as machinery, automotive, and outdoor equipment. The hex drive allows for precise torque control during installation, reducing the risk of stripping and ensuring consistent clamping force. Its compliance with DIN 914 and ISO 4027 standards guarantees dimensional accuracy and interoperability, providing engineers with a reliable component for precision assemblies.
