S-91210A437 M8 x 25 mm DIN 914, ISO 4027 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with 90° cone point tip that bites into mating surfaces for permanent, vibration-resistant positioning
• Exceptional durability thanks to alloy steel construction with Rockwell C45 hardness rating, resisting wear and deformation under heavy loads
• Precise thread engagement with Class 5g6g thread fit ensuring consistent, reliable fastening in demanding industrial applications
• Optimized installation through 4mm hex drive design that provides excellent torque transmission while maintaining headless profile
• Industry-standard compatibility with coarse 1.25mm thread pitch meeting DIN 914 and ISO 4027 specifications for global applications
• Environmental compliance with RoHS 3 and REACH regulations, making them suitable for regulated industries and international markets
• Space-saving design as a headless set screw that sits flush with or below the surface of assembled components

Professional Applications & Engineering Value

This M8 set screw delivers exceptional engineering value in applications requiring permanent component positioning and vibration resistance. The alloy steel construction with Rockwell C45 hardness ensures the fastener maintains its structural integrity under repeated stress cycles, while the 90° cone point design creates positive mechanical locking by embedding into the mating surface. The coarse 1.25mm thread pitch provides rapid installation and superior holding power in softer materials or where vibration is a concern. These hex headless set screws are particularly valuable in machinery assembly, automotive components, and precision equipment where flush mounting and reliable positioning are critical. Meeting DIN 914 and ISO 4027 standards ensures dimensional consistency and interchangeability across global manufacturing operations.
