S-94285A365 M4 x 8 mm ISO 4029 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with serrated locking mechanism that prevents loosening under vibration and dynamic loads
• Exceptional durability through Rockwell C45 hardened alloy steel construction resisting wear and deformation
• Precise installation control with 2mm hex drive allowing high torque application in confined spaces
• Reliable coarse thread engagement with Class 6g tolerance ensuring consistent fastening in various materials
• Optimized force distribution through cup tip design that concentrates clamping pressure effectively
• Space-saving headless design enabling flush mounting where protruding fasteners aren't feasible
• Global compliance assurance meeting ISO 4029 specifications and environmental regulations including RoHS 3 & REACH

Professional Applications & Engineering Value

This M4 x 0.7mm alloy steel set screw delivers critical performance in demanding industrial applications where vibration resistance and space constraints challenge conventional fasteners. The serrated locking mechanism creates permanent positioning in pulleys, gears, and collars, eliminating the need for additional locking components. Engineered with Rockwell C45 hardness, the screw maintains its structural integrity under repeated stress cycles, while the headless design with 2mm hex drive enables installation in deeply recessed locations. The coarse metric thread provides rapid assembly in both metallic and composite materials, making it ideal for production lines requiring efficiency and reliability. These set screws are particularly valuable in precision machinery, automotive systems, and industrial equipment where permanent fastening solutions must withstand operational extremes without maintenance intervention.

Specification Summary & Compliance

This metric set screw features M4 x 0.7mm coarse threads manufactured to Class 6g tolerance for precise fitment. The fastener complies with ISO 4029 manufacturing specifications ensuring dimensional accuracy and performance consistency. Environmental compliance is verified through RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) certifications, confirming the absence of restricted substances. The right-hand thread direction and 8mm length provide standardized installation across industrial applications, while the cup tip design ensures optimal surface contact for secure positioning.
