S-99642A214 M12 x 25 mm DIN 916, ISO 4029 Set Screws

Key Features & Benefits at a Glance

• Exceptional holding power with alloy steel construction and Rockwell C45 hardness for reliable, long-term fastening in demanding applications
• Precise positioning and minimal backlash due to the M12 x 1.25mm extra fine thread and Class 5g6g thread fit, ensuring superior alignment
• High torque transmission and flush installation enabled by the headless design with a 6mm hex drive, ideal for confined spaces
• Enhanced grip and resistance to loosening from the cup tip, which bites into the contact surface for secure assemblies
• Guaranteed dimensional consistency and interchangeability through compliance with DIN 916 and ISO 4029 standards
• Safe for use in regulated industries as it is fully RoHS 3 and REACH compliant, meeting strict environmental and safety directives
• Optimized for 25mm depth applications, providing a robust and compact fastening solution for precision components

Professional Applications & Engineering Value

This alloy steel set screw is engineered to address critical challenges in precision machinery and assembly lines. Its extra fine metric thread (M12 x 1.25mm) and Class 5g6g thread fit deliver exceptional accuracy, minimizing play and vibration in components like gears, pulleys, and collars. The headless design with a hex drive allows for a flush finish, preventing interference in compact systems while enabling high torque application. The cup tip concentrates pressure for a superior bite, resisting rotational forces and maintaining position under dynamic loads. Manufactured to DIN 916 / ISO 4029 specifications, this screw ensures reliability in automotive, aerospace, and industrial equipment where precision and durability are non-negotiable.
