S-92905A653 M24 x 25 mm DIN 915, ISO 4028 Set Screws

Key Features & Benefits at a Glance

• Exceptional holding power with Rockwell C45 hardness for superior resistance to wear, deformation, and loosening under heavy loads.
• Precise and secure positioning thanks to the extended 6.3mm tip, ensuring deeper engagement and a more reliable grip in the mating part.
• Optimized for high-strength applications using durable alloy steel, providing excellent mechanical properties and fatigue resistance.
• Simplified installation and removal with a headless design and internal hex drive, allowing for a flush finish and easy access in confined spaces.
• Reliable thread engagement with a Class 6g tolerance coarse thread (M24 x 3mm), facilitating faster assembly and robust performance in demanding environments.
• Guaranteed quality and interchangeability through compliance with DIN 915 and ISO 4028 international standards.
• Safe for regulated industries as it is RoHS 3 and REACH compliant, meeting strict environmental and safety directives.

Professional Applications & Engineering Value

This M24 set screw is engineered to solve critical challenges in heavy-duty industrial applications where vibration, high stress, and precise component alignment are constant concerns. The alloy steel construction, combined with the Rockwell C45 hardness, ensures it can withstand significant shear and tensile forces without failing, making it ideal for securing gears, pulleys, and collars on shafts. The extended tip provides a concentrated point of contact, creating a deeper dimple in the shaft for a more positive and permanent lock, effectively preventing axial movement. Its headless design and internal hex drive offer a clean, flush installation, which is crucial in machinery with rotating parts to avoid interference. This metric fastener delivers reliable performance in automotive, aerospace, and heavy machinery assembly, where precise fastening solutions are non-negotiable.
