S-93339A261 M16 x 38.3 mm Set Screws

Key Features & Benefits at a Glance

• Exceptional holding power with coarse 2mm pitch threads for reliable, vibration-resistant fastening in high-stress applications
• Superior material strength from alloy steel construction with Rockwell C39 hardness to withstand heavy loads and prevent deformation
• Precise thread engagement with Class 6g tolerance ensuring consistent fit and optimal torque transmission in metric assemblies
• Secure installation and removal via 8mm hex drive that provides excellent torque transfer while maintaining a clean, headless profile
• Reduced surface damage from the precision ball tip design that minimizes marring on contacted components during clamping
• Long-term durability with robust alloy steel tip material that maintains performance through repeated adjustment cycles
• Environmental compliance meeting RoHS 3 standards for use in regulated industries and international markets

Professional Applications & Engineering Value

This M16 set screw delivers critical engineering solutions for industrial applications requiring secure component positioning. The alloy steel construction and Rockwell C39 hardness provide exceptional resistance to vibrational loosening and shear forces in machinery, automotive, and heavy equipment assemblies. The coarse metric thread with 2mm pitch ensures rapid installation and superior holding power in soft materials or where frequent adjustments are necessary. The headless design with 8mm hex drive allows for flush mounting in confined spaces while maintaining high torque capability. The precision ball tip distributes clamping force evenly, preventing damage to shafts and gears during securement. This combination of features makes it ideal for permanent fastening applications where reliability and Class 6g thread fit precision are paramount.

Specification Summary & Compliance

This metric set screw features M16x2mm coarse threads with Class 6g tolerance for precise fit in accordance with ISO metric standards. The 38.3mm length and 12mm ball tip diameter provide consistent engagement across applications. Manufactured from high-strength alloy steel, the fastener is RoHS 3 (2015/863/EU) compliant with exemption 6(a) for lead as an alloying element in steel, ensuring suitability for regulated industrial environments and international supply chains.
