S-94285A630 M8 x 20 mm ISO 4029 Set Screws

Key Features & Benefits at a Glance

• Superior vibration resistance through precision serrations that create permanent locking action without requiring additional fasteners
• Exceptional durability with Rockwell C45 hardness alloy steel construction that withstands heavy loads and repeated use
• Precise thread engagement with Class 6g metric coarse threads ensuring reliable installation and consistent clamping force
• Space-saving design as a headless set screw that fits flush in applications where clearance is limited
• Enhanced grip capability with cup tip design that concentrates pressure for secure component positioning
• Easy installation and removal using standard 4mm hex keys for efficient maintenance and adjustments
• Global compliance assurance meeting ISO 4029 specifications and environmental regulations for international projects

Professional Applications & Engineering Value

This M8 set screw delivers critical engineering solutions where vibration resistance and permanent positioning are paramount. The alloy steel construction with Rockwell C45 hardness provides exceptional strength for demanding applications including machinery components, gear assemblies, and precision equipment. The serrated locking type eliminates the need for additional locking devices by creating mechanical interference that prevents loosening under continuous vibration. With metric coarse threading (1.25mm pitch) and Class 6g thread fit, installation is streamlined while maintaining precise tolerances. The headless design and cup tip work together to provide flush mounting and concentrated clamping force, making this hex headless set screw ideal for collars, pulleys, and gears where space constraints and reliability are critical concerns.

Specification Summary & Compliance

This metric set screw features precise Class 6g thread fit with M8 x 1.25mm coarse thread specifications. Manufactured to ISO 4029 standards for dimensional accuracy and performance reliability. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in international industrial applications. The 20mm length and 4mm hex drive provide consistent installation across production runs.
