S-91210A220 M5 x 10 mm DIN 914, ISO 4027 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with 90° cone point design that bites firmly into materials for secure, permanent fastening
• Exceptional durability thanks to alloy steel construction with Rockwell C45 hardness for long-term reliability in demanding applications
• Precise installation control with 2.5mm hex drive that prevents cam-out and allows high torque application in confined spaces
• Reliable thread engagement with Class 5g6g thread fit ensuring consistent performance and vibration resistance
• Wide industrial compatibility through DIN 914/ISO 4027 standardization and metric coarse threading (M5x0.8)
• Environmental compliance meeting RoHS 3 and REACH regulations for safe use across global markets
• Space-saving design as a headless set screw that sits flush with surfaces in compact assemblies

Professional Applications & Engineering Value

This M5 set screw delivers critical engineering solutions where permanent positioning and vibration resistance are paramount. The alloy steel construction with Rockwell C45 hardness ensures the cone point maintains its sharp 90° angle through repeated installations, preventing rounding that compromises grip strength. The hex headless design with 2.5mm drive is particularly valuable in machinery, automotive, and precision equipment where space constraints demand low-profile fasteners that can withstand high rotational forces. The Class 5g6g thread fit and coarse metric threading provide excellent resistance to loosening under dynamic loads, making these set screws ideal for securing gears, pulleys, and collars on rotating shafts in industrial environments.
