S-94285A633 M8 x 25 mm ISO 4029 Set Screws

Key Features & Benefits at a Glance

• Superior locking performance with precision serrations that prevent loosening under vibration and dynamic loads
• Exceptional durability from alloy steel construction with Rockwell C45 hardness for long service life in demanding environments
• Reliable thread engagement with Class 6g thread fit ensuring consistent performance and easy installation
• Secure fastening action from the cup point design that creates positive seating and resists rotational forces
• Streamlined installation with 4mm hex drive allowing for efficient torque application in confined spaces
• Industry-standard compatibility with metric coarse thread (M8 x 1.25mm) for broad application across equipment and machinery
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe use in regulated industries

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 the structural integrity needed for heavy-duty applications, while the precision serrations create micro-locking action that prevents back-off in rotating assemblies and machinery components. The cup point design bites into mating surfaces, ensuring zero movement in pulleys, gears, and collars. With its 4mm hex drive and headless configuration, it offers flush mounting in space-constrained applications across automotive, industrial machinery, and precision equipment. The metric coarse thread (M8 x 1.25mm) with Class 6g tolerance guarantees consistent performance in high-stress environments where reliability cannot be compromised.

Specification Summary & Compliance

This set screw features M8 x 1.25mm metric coarse threads with Class 6g thread fit for precision tolerance. Manufacturing and quality control adhere to ISO 4029 specifications, ensuring dimensional accuracy and performance reliability. The fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for use in regulated industries and international markets. The 25mm length and right-hand thread direction provide standardized installation across various applications.
