S-92098A125 M3 x 5 mm DIN 551, ISO 4766 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with Class 6g thread fit for reliable, vibration-resistant fastening in demanding applications
• Exceptional durability from alloy steel construction with Rockwell B67 hardness, resisting wear and deformation under load
• Precise metric threading (M3 x 0.5 mm coarse pitch) ensures quick assembly and secure engagement with mating components
• Space-saving headless design with slotted drive allows for flush mounting where clearance is limited
• Flat tip configuration provides maximum contact surface for superior grip and minimal component damage
• Full regulatory compliance with RoHS 3 and REACH standards, making them suitable for global industrial markets
• Standardized dimensions per DIN 551 and ISO 4766 ensure interchangeability and consistent performance

Professional Applications & Engineering Value

This M3 set screw delivers critical engineering value in applications requiring secure axial positioning of components on shafts and hubs. The alloy steel construction combined with Rockwell B67 hardness provides excellent resistance to loosening under vibration, a common failure point in machinery and automotive assemblies. The headless slotted drive design is ideal for confined spaces where traditional screw heads would interfere, while the flat tip distributes clamping force evenly to prevent damage to precision surfaces. With metric coarse threading (0.5 mm pitch), installation is faster and less prone to cross-threading compared to fine-pitch alternatives, making these set screws particularly valuable in production environments where speed and reliability are paramount.

Specification Summary & Compliance

This metric set screw features M3 x 0.5 mm coarse thread with Class 6g tolerance per ISO standards, ensuring precise fit and consistent performance. Manufactured to DIN 551 and ISO 4766 specifications for dimensional accuracy and mechanical properties. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, containing no restricted substances above threshold limits.
