S-91210A112 M4 x 6 mm DIN 914, ISO 4027 Set Screws

Key Features & Benefits at a Glance

• Exceptional holding power with a 90° cone point that bites into materials for secure, vibration-resistant fastening.
• Superior strength and durability from high-grade alloy steel hardened to Rockwell C45, resisting wear and deformation under load.
• Precise and reliable installation with a 2mm hex drive, ensuring high torque application without cam-out for consistent assembly.
• Optimized for quick assembly with a coarse M4 x 0.7mm thread and Class 5g6g fit, providing easy starts and robust engagement.
• Space-saving headless design allows for flush mounting in applications where clearance is limited.
• Guaranteed industrial compatibility by meeting DIN 914 and ISO 4027 standards for dimensional accuracy and performance.
• Safe for regulated environments with compliance to RoHS 3 and REACH, ensuring no hazardous substances are used.

Professional Applications & Engineering Value

This alloy steel set screw is engineered to solve critical challenges in industrial assembly, where loosening under vibration or stress can lead to equipment failure. The M4 metric thread with a coarse 0.7mm pitch and Class 5g6g fit ensures rapid, secure fastening in metals and composites, reducing installation time while maintaining integrity. The 90° cone point concentrates force for a deep, non-slip grip, ideal for securing collars, gears, and pulleys on shafts. Made from Rockwell C45 hardened alloy steel, it withstands high shear and tensile loads, making it a reliable choice for machinery, automotive, and precision tooling applications that demand long-term holding power and durability.
