S-93339A231 M10 x 21.7 mm Set Screws

Key Features & Benefits at a Glance

• Exceptional holding power with M10 coarse thread for rapid installation and reduced cross-threading risk in high-vibration environments
• Superior material strength from alloy steel construction, hardened to Rockwell C39 for excellent wear resistance and long-term reliability
• Secure, flush-mount fastening enabled by the headless design and 7mm ball tip for positive seating without protruding components
• High-torque installation capability via the internal 5mm hex drive, providing a secure tool grip and preventing driver slippage
• Precision thread fit meeting Class 6g tolerance ensures consistent engagement and reliable performance in demanding applications
• Environmental compliance assurance with RoHS 3 exemption 6(a) for safe use in regulated industrial settings
• Optimized 21.7mm length provides versatile application fit while maintaining structural integrity under load

Professional Applications & Engineering Value

This M10 x 1.5mm alloy steel set screw delivers critical engineering solutions for industrial assembly challenges. The hex headless design with ball tip creates a secure, flush fastening point that prevents component shifting in high-torque applications while eliminating protrusion hazards. Manufactured from hardened alloy steel with Rockwell C39 hardness, it withstands repetitive stress and vibration better than standard fasteners. The coarse thread pitch combined with Class 6g thread fit ensures rapid installation with minimal cross-threading risk, making it ideal for production environments where speed and reliability are paramount. These characteristics make it particularly valuable for securing gears, pulleys, and collars in machinery, automotive, and heavy equipment applications where permanent fastening solutions are required.

Specification Summary & Compliance

This metric set screw features M10 x 1.5mm coarse threads manufactured to Class 6g tolerance for precision fit. The 21.7mm length with 7mm ball tip provides consistent seating performance. Manufactured from alloy steel hardened to Rockwell C39 and featuring a 5mm hex drive for secure installation. Compliant with RoHS 3 (2015/863/EU) under exemption 6(a) for lead as an alloying element in steel, ensuring environmental regulation adherence for industrial use.
