S-91210A813 M5 x 20 mm DIN 914, ISO 4027 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated alloy steel construction, extending service life in harsh industrial environments
• Exceptional holding power ensured by the 90° cone point design, providing reliable component positioning without slippage
• Optimized torque transmission through the 2.5 mm hex drive, enabling secure installation with standard tools
• Precision thread engagement with Class 5g6g thread fit, delivering consistent clamping force in repetitive assemblies
• Enhanced mechanical strength from Rockwell C45 hardness, maintaining dimensional stability under vibration and load
• Quick installation advantage with coarse thread (0.8 mm pitch), reducing assembly time in high-volume production
• Regulatory compliance assurance meeting DIN 914/ISO 4027 standards, guaranteeing interchangeability and quality consistency

Professional Applications & Engineering Value

This M5 set screw delivers critical engineering solutions where precise component alignment and vibration resistance are paramount. The zinc-plated alloy steel construction provides essential corrosion protection for machinery, automotive subsystems, and electrical enclosures exposed to operational stresses. Its cone point with 90° angle creates concentrated radial pressure, preventing axial movement in pulleys, gears, and collars—effectively solving retention challenges in rotating assemblies. The headless design and metric coarse thread enable flush mounting in confined spaces while maintaining rapid installation cycles. Manufactured to DIN 914/ISO 4027 specifications, these hex drive set screws ensure dimensional compatibility with existing tooling and components, reducing redesign costs across industrial maintenance and OEM applications.

Specification Summary & Compliance

This metric set screw maintains Class 5g6g thread tolerance per ISO standards, ensuring precise fit in threaded holes. The M5 x 0.8 mm coarse thread configuration follows standardized pitch dimensions for consistent engagement. Manufacturing complies with DIN 914/ISO 4027 mechanical and dimensional requirements, while environmental regulations including RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) are fully met for hazardous substance restrictions.
