S-93339A256 M10 x 41.7 mm Set Screws

Key Features & Benefits at a Glance

• Superior holding power with a precision 7mm ball tip that digs into mating parts to prevent loosening under vibration and load
• Exceptional durability and wear resistance thanks to high-strength alloy steel construction and Rockwell C39 hardness
• Reliable, coarse thread engagement with a Class 6g metric thread fit for easy assembly and consistent clamping force
• Secure, flush installation enabled by the headless design and 5mm hex drive, ideal for confined spaces
• Wide industrial compatibility with right-hand M10x1.5mm coarse threads meeting common metric fastener standards
• Environmental compliance assurance as it is RoHS 3 compliant, meeting strict regulations for industrial use
• Optimized for high-stress applications where a ball tip set screw is needed for permanent, tamper-resistant positioning

Professional Applications & Engineering Value

This M10 set screw is engineered from alloy steel to solve critical challenges in industrial assembly, such as shaft collars, gears, and pulleys slipping under torque. The ball tip concentrates force on a small contact area, creating a permanent dimple in the shaft for superior resistance to rotational forces. With a Class 6g thread and coarse 1.5mm pitch, it ensures rapid installation and high clamp load in demanding applications. The hex headless design allows completely flush mounting, preventing interference in compact machinery. Combined with Rockwell C39 hardness, this metric set screw delivers long-term reliability, reducing maintenance and downtime in automation, automotive, and heavy equipment sectors.

Specification Summary & Compliance

This set screw features an M10x1.5mm coarse thread with a Class 6g tolerance for precise fit. It is manufactured from alloy steel with a ball tip diameter of 7mm and overall length of 41.7mm. The 5mm hex drive ensures secure tool engagement. It is RoHS 3 (2015/863/EU) compliant with exemption 6(a) for lead as an alloying element in steel, adhering to environmental and industry standards for safe use in global markets.
