S-91210A796 M4 x 8 mm DIN 914, ISO 4027 Set Screws

Key Features & Benefits at a Glance

• Superior vibration resistance with the 90° cone point design that bites into mating surfaces for secure, permanent positioning
• Exceptional durability and corrosion protection from the zinc-plated alloy steel construction, extending service life in demanding environments
• High-strength performance backed by a Rockwell C45 hardness rating, resisting wear and deformation under load
• Reliable and precise fit ensured by the Class 5g6g thread tolerance, providing consistent engagement and reducing the risk of cross-threading
• Easy and secure installation with the internal hex drive (2 mm), allowing for high torque application in confined, headless designs
• Broad industrial compatibility with the standard M4 x 0.7 mm coarse right-hand metric thread, facilitating easy replacement and sourcing
• Compliance with global standards including DIN 914 and ISO 4027, guaranteeing quality and interchangeability for international projects

Professional Applications & Engineering Value

This M4 set screw is engineered to solve critical challenges in precision assembly and motion control systems. The zinc-plated alloy steel material provides a robust barrier against corrosion, essential for machinery operating in humid or variable conditions. The 90° cone point is specifically designed to exert concentrated pressure, creating a permanent lock on shafts, collars, and gears to prevent slippage under high vibrational loads—common in automotive, robotics, and conveyor systems. The headless design with a hex drive allows for flush mounting in tight spaces where protruding fasteners are not feasible. Manufactured to DIN 914 / ISO 4027 specifications, this metric set screw delivers reliable performance in applications requiring exact alignment and repeatable clamping force, reducing maintenance downtime and enhancing operational safety.
