S-91210A717 M5 x 45 mm DIN 914, ISO 4027 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with a 90° cone point that bites into materials, preventing component slippage and ensuring reliable positioning.
• Exceptional durability and wear resistance thanks to the high-strength alloy steel construction and Rockwell C45 hardness rating.
• Easy and secure installation with a 2.5mm hex drive, allowing for high torque application in confined, headless designs.
• Precise and reliable coarse threading (M5 x 0.8mm) with a Class 5g6g fit, enabling quick assembly and robust fastening in a wide range of materials.
• Guaranteed quality and interchangeability as it is manufactured to meet the stringent DIN 914 and ISO 4027 standards.
• Safe for use in regulated industries with full compliance to RoHS 3 and REACH environmental directives.
• Versatile right-hand thread design for standard industrial applications, ensuring compatibility with common assembly practices.

Professional Applications & Engineering Value

This M5 set screw is engineered to solve critical challenges in precision assembly and motion control systems. The alloy steel construction and Rockwell C45 hardness provide the necessary strength to resist vibrational loosening and shear forces in demanding environments like automotive transmissions, robotics, and heavy machinery. The headless design with a hex drive is ideal for applications where space is limited and a flush finish is required. The 90° cone point concentrates force to create a secure, permanent lock on shafts, gears, and pulleys, preventing axial movement and maintaining alignment. This makes it an indispensable metric set screw for engineers who require a reliable, high-strength fastener that delivers consistent performance and long-term durability in industrial settings.

Specification Summary & Compliance
