S-93339A266 M20 x 64.2 mm Set Screws

Key Features & Benefits at a Glance

• Exceptional holding power from high-strength alloy steel construction, ideal for permanent fastening in demanding industrial environments
• Superior wear and deformation resistance due to Rockwell C39 hardness, ensuring long-term reliability and reduced maintenance
• Secure and flush installation with a headless hex drive design, providing a clean finish and preventing snagging
• Enhanced grip and reduced component damage from the durable 15mm ball tip, which distributes pressure evenly on the contact surface
• Reliable and precise thread engagement with a Class 6g metric coarse thread fit, minimizing the risk of cross-threading and ensuring consistent performance
• Easy installation and removal using a standard 10mm hex key, streamlining assembly and disassembly processes
• Compliance with environmental regulations as it is RoHS 3 compliant, making it suitable for use in regulated markets and sustainable manufacturing

Professional Applications & Engineering Value

This M20 set screw is engineered to solve critical fastening challenges in industrial machinery, automotive assemblies, and heavy-duty equipment. The high-strength alloy steel and Rockwell C39 hardness provide exceptional resistance to vibrational loosening and shear forces, a common failure point in dynamic applications. The headless design with a 10mm hex drive allows for a flush fit in tight spaces, preventing interference and improving safety. The ball tip is specifically designed to minimize marring on shafts and components, preserving the integrity of expensive parts while maintaining a strong grip. With its Class 6g coarse thread, it ensures quick assembly and reliable holding power, making it an indispensable component for engineers seeking durability and precision in their metric set screw solutions.

Specification Summary & Compliance

This set screw adheres to metric (M20x2.5) threading standards with a Class 6g thread fit for precise dimensional accuracy. It is manufactured from alloy steel and features a right-hand, coarse thread with a 64.2mm length and 15mm ball tip diameter. The product is RoHS 3 (2015/863/EU) compliant with exemption 6(a) for lead as an alloying element in steel, ensuring it meets stringent environmental and safety regulations for industrial use.
