S-94285A327 M3 x 8 mm ISO 4029 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with serrations locking that prevents loosening under vibration and dynamic loads in industrial machinery.
• Exceptional durability and wear resistance thanks to alloy steel construction with Rockwell C45 hardness, ensuring long service life in harsh environments.
• Easy and secure installation using a standard 1.5 mm hex key, providing reliable torque transfer without head protrusion for space-constrained assemblies.
• Precise thread engagement with Class 6g metric coarse threads (M3 x 0.5 mm) for quick assembly and reduced cross-threading risks.
• Effective surface grip and alignment from the cup tip design, distributing pressure evenly and minimizing component damage.
• Broad compatibility with right-hand thread direction and coarse pitch, ideal for common metric fastener systems in global manufacturing.
• Compliance with international standards including ISO 4029, ensuring consistent quality and performance in regulated applications.

Professional Applications & Engineering Value

This M3 set screw is engineered to address critical challenges in precision assemblies, such as securing gears, pulleys, and collars on shafts without slipping. The alloy steel material and Rockwell C45 hardness provide excellent resistance to shear and fatigue, making it suitable for high-stress environments in automotive, aerospace, and machinery sectors. Its hex headless design with a 1.5 mm hex drive allows for flush mounting in tight spaces, while the serrations locking and cup tip enhance grip on contacted surfaces, reducing the need for additional locking mechanisms. With a coarse metric thread (M3 x 0.5 mm) and Class 6g thread fit, it ensures rapid installation and reliable performance in dynamic applications, minimizing downtime and maintenance costs.

Specification Summary & Compliance

This set screw features precise metric coarse threads with M3 diameter, 0.5 mm pitch, and Class 6g thread fit per ISO standards for consistent dimensional accuracy. It is manufactured in compliance with ISO 4029 specifications and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in industrial and electronic applications worldwide.
