S-93245A627 M2 x 4 mm DIN 913, ISO 4026 Set Screws

Key Features & Benefits at a Glance

• Superior holding power thanks to alloy steel construction and Rockwell C45 hardness, ensuring long-term joint integrity and resistance to loosening under vibration.
• Precise Class 5g6g thread fit guarantees consistent engagement and reliable clamping force in demanding applications.
• Compact, headless design allows for flush installation in confined spaces, ideal for machinery and assemblies where protrusion is not permissible.
• Hex drive (0.9mm) provides a secure grip for high-torque installation, reducing the risk of tool slippage and head stripping.
• Coarse thread (M2 x 0.4mm pitch) enables faster installation and improved performance in softer materials or where frequent adjustments are needed.
• Full compliance with DIN 913 and ISO 4026 standards ensures dimensional accuracy, interchangeability, and global sourcing compatibility.
• Meets RoHS 3 and REACH regulations, making it a safe and environmentally responsible choice for various industrial sectors.

Professional Applications & Engineering Value

This M2 set screw is engineered to solve critical fastening challenges in precision assemblies. Its alloy steel core, hardened to Rockwell C45, provides the necessary high strength to prevent shear failure and maintain clamp load in vibrating environments like motors, gearboxes, and automation equipment. The headless and flat tip design is specifically valuable for securing collars, pulleys, and knobs onto shafts without interfering with adjacent components. The hex drive allows for significant torque application, ensuring the set screw is seated firmly, while the right-hand coarse thread (M2 x 0.4mm) offers quick and reliable installation, reducing assembly time and labor costs in high-volume production settings.

Specification Summary & Compliance

This metric set screw conforms to the dimensional and tolerance requirements of DIN 913 / ISO 4026. The thread fit is Class 5g6g, ensuring high precision for the external thread. It is manufactured from alloy steel and features a flat tip. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its adherence to strict environmental and safety standards for industrial use.
