S-93245A213 M5 x 5 mm DIN 913, ISO 4026 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with Class 5g6g thread fit ensuring precise, reliable engagement in demanding applications.
• Exceptional durability and wear resistance provided by alloy steel construction and a Rockwell C45 hardness rating.
• Secure, flush-mount fastening thanks to the headless design and flat tip, preventing protrusion and component damage.
• High-torque installation capability enabled by the internal 2.5 mm hex drive, allowing for a secure grip and easy assembly.
• Wide compatibility and interchangeability guaranteed by adherence to DIN 913 and ISO 4026 international standards.
• Resistance to loosening under vibration from the coarse (0.8mm pitch) right-hand thread, ideal for dynamic industrial environments.
• Safe for use in regulated industries as it is fully RoHS 3 and REACH compliant, meeting strict environmental and safety directives.

Professional Applications & Engineering Value

This M5 set screw is engineered to solve critical fastening challenges in precision assemblies. The high-strength alloy steel material and Rockwell C45 hardness provide exceptional resistance to shear forces and wear, making it ideal for securing pulleys, gears, and knobs on shafts in machinery and automotive systems. Its headless, flat tip design allows for a completely flush finish, eliminating interference in compact spaces. The internal hex drive offers superior torque transmission compared to slotted drives, reducing the risk of tool slippage and head stripping during high-stress installations. This combination of a coarse metric thread and robust material ensures reliable performance in industrial applications subject to vibration and heavy loads, providing a durable and maintenance-free fastening solution.

Specification Summary & Compliance

This metric set screw features an M5 x 0.8mm coarse thread with a Class 5g6g thread fit tolerance, ensuring high precision and interchangeability.
