S-91210A713 M5 x 25 mm DIN 914, ISO 4027 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with a 90° cone point that digs securely into materials, preventing component slippage under vibration or load.
• Exceptional durability and wear resistance thanks to Alloy Steel construction hardened to Rockwell C45, ensuring a long service life in demanding applications.
• Reliable and precise coarse threading (M5x0.8mm) with a Class 5g6g fit for easy, fast assembly and consistent clamping force.
• Space-saving headless design with a 2.5mm hex drive allows for installation in confined spaces and provides high torque capability without stripping.
• Guaranteed industrial-grade quality, manufactured to meet DIN 914 and ISO 4027 standards for dimensional accuracy and performance.
• Safe for use in regulated environments as it is fully compliant with RoHS 3 and REACH environmental directives.
• Right-hand thread direction ensures standard, intuitive installation for efficient assembly line operations.

Professional Applications & Engineering Value

This M5 set screw is engineered to solve critical challenges in machinery assembly and precision engineering. The alloy steel material, hardened to Rockwell C45, provides the necessary strength to resist deformation under high stress, making it ideal for securing gears, pulleys, and collars on shafts. The 90° cone point and coarse thread design offer superior bite and resistance to loosening caused by vibration, a common failure point in dynamic industrial equipment. Its headless and hex drive configuration is perfect for applications where flush mounting is required and space is limited, ensuring a secure fit without protruding parts. This metric set screw delivers reliable performance in automotive, aerospace, and heavy machinery applications, providing engineers with a trusted component for permanent or semi-permanent fastening solutions.
