S-93245A173 M12 x 20 mm DIN 913, ISO 4026 Set Screws

Key Features & Benefits at a Glance

• Exceptional holding power through alloy steel construction with Rockwell C45 hardness for superior resistance to wear and deformation in demanding applications
• Precise thread engagement with Class 5g6g thread fit ensuring reliable, vibration-resistant connections and reduced risk of loosening
• High-torque installation capability via the 6 mm hex drive design, allowing for secure tightening in confined spaces without head protrusion
• Optimized for quick assembly with right-hand coarse (1.75 mm pitch) threads that enable faster installation compared to fine-thread alternatives
• Secure surface contact provided by the flat tip design, minimizing component damage while maintaining consistent clamping force
• Guaranteed dimensional consistency through compliance with DIN 913 and ISO 4026 standards, ensuring interchangeability and reliable performance
• Safe for regulated industries with full compliance to RoHS 3 and REACH environmental regulations, supporting responsible manufacturing practices

Professional Applications & Engineering Value

This M12 set screw delivers critical engineering value in applications requiring secure axial positioning of components on shafts, hubs, and collars. The alloy steel material, hardened to Rockwell C45, provides exceptional shear strength and fatigue resistance, solving common failure points in high-vibration environments like motor assemblies, gearboxes, and heavy machinery. The hex headless design and flat tip allow for flush mounting without interfering with adjacent parts, while the coarse metric threads ensure rapid installation and reliable holding in both soft and hard materials. Engineered to DIN 913/ISO 4026 specifications, it offers predictable performance for maintenance and OEM applications across automotive, industrial equipment, and precision engineering sectors.
