S-91210A835 M16 x 25 mm DIN 914, ISO 4027 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with 90° cone point design that bites deeply into materials for maximum resistance against loosening
• Exceptional durability from Rockwell C45 hardened alloy steel construction that withstands heavy loads and repeated adjustments
• Precise thread engagement with Class 5g6g tolerance ensuring reliable fit and consistent clamping force in demanding applications
• Easy installation and removal thanks to the 8mm hex drive that provides excellent torque transmission without stripping
• Reliable coarse threading (M16x2mm) that resists vibration-induced loosening better than fine-pitch alternatives
• Space-saving headless design that allows flush mounting where clearance is limited
• Global compliance assurance meeting DIN 914/ISO 4027 standards plus RoHS 3 and REACH environmental regulations

Professional Applications & Engineering Value

This M16 set screw delivers critical engineering value in applications where vibration resistance and permanent positioning are paramount. The alloy steel construction with Rockwell C45 hardness provides the necessary strength and wear resistance for heavy machinery components, automotive assemblies, and industrial equipment. The 90° cone point creates a deep indentation in mating surfaces, solving the common problem of component slippage under dynamic loads. As a headless fastener with metric coarse threading, it offers space-efficient solutions for shaft collars, gears, and pulleys where traditional fasteners cannot be used. The hex drive design ensures reliable installation in confined spaces while maintaining the integrity of the drive interface during high-torque applications.

Specification Summary & Compliance

This precision set screw features M16x2mm coarse thread with Class 5g6g tolerance per ISO metric standards, ensuring precise fit and reliable performance. Manufactured to DIN 914 and ISO 4027 specifications with right-hand threading and 25mm length. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for global industrial applications requiring strict material compliance.
