S-91217A155 M5 x 5 mm DIN 914, ISO 4027 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and extended service life.
• Secure and permanent fastening thanks to the 120° cone point design, which bites into materials to prevent component slippage.
• High mechanical strength with a Rockwell B80 hardness rating, ensuring the set screw maintains its form under high clamping loads.
• Easy and reliable installation using a standard 2.5 mm hex key, providing a secure drive that minimizes tool slippage and head stripping.
• Precise and reliable thread engagement with a Class 6g tolerance on the coarse M5x0.8mm thread, ensuring consistent performance and fit.
• Compliance with major international standards including DIN 914 / ISO 4027, guaranteeing dimensional accuracy and interchangeability.
• Safe for use in regulated industries as it is fully compliant with RoHS 3 and REACH environmental directives.

Professional Applications & Engineering Value

This M5 DIN 914 set screw is engineered to solve critical challenges in precision assembly and motion control systems. Its headless design and cone point are ideal for securing collars, gears, and pulleys onto shafts where a flush finish is required and rotational slippage must be prevented. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, making it a reliable choice for applications in machinery, automotive, and outdoor equipment exposed to moisture or chemicals. The coarse metric thread (M5x0.8mm) allows for faster installation and greater resistance to vibration loosening compared to fine-pitch alternatives. Paired with a 2.5 mm hex drive, it offers a high-torque solution for set-and-forget applications, ensuring your components remain securely locked in place.
