S-99642A181 M10 x 10 mm DIN 916, ISO 4029 Set Screws

Key Features & Benefits at a Glance

• Exceptional holding power with fine 1.25mm pitch threading for superior resistance to vibration and loosening in demanding applications
• High-strength alloy steel construction with Rockwell C45 hardness ensures excellent durability and long-term reliability under heavy loads
• Secure, flush installation thanks to the headless design, ideal for applications where protruding components are not permissible
• Easy and precise installation with the 5mm hex drive, allowing for high torque application without slippage
• Enhanced grip and component security provided by the cup tip design, which bites into the contact surface for maximum fastening integrity
• Precision thread fit (Class 5g6g) ensures consistent performance and reliable engagement with mating components
• Full regulatory compliance with RoHS 3 and REACH, making it suitable for use in environmentally conscious and regulated industries

Professional Applications & Engineering Value

This M10 set screw is engineered to solve critical fastening challenges in industrial and mechanical assemblies. The fine pitch metric thread (1.25mm) provides a greater number of threads per unit length compared to coarse threads, significantly enhancing resistance to vibrational loosening—a common failure point in machinery and moving parts. Manufactured from alloy steel and heat-treated to a Rockwell C45 hardness, it delivers the necessary tensile strength for high-stress applications, from securing gears on shafts to aligning components in precision equipment. The headless design with hex drive allows for a completely flush finish, essential in confined spaces or rotating assemblies where clearance is limited. The cup tip concentrates pressure on a small contact area, creating a permanent locking effect that prevents axial movement. Fully compliant with DIN 916 and ISO 4029 standards, this set screw guarantees dimensional accuracy and interchangeability, making it a reliable choice for OEMs and maintenance professionals in automotive, aerospace, and industrial machinery sectors.
