S-91390A709 M10 x 18 mm DIN 916 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with a cup point tip that bites into surfaces to prevent component slippage and rotation
• Exceptional strength and durability provided by alloy steel construction and a Rockwell C45 hardness rating for reliable performance under stress
• Precise and secure installation enabled by the 5mm hex drive, allowing for high torque application without head protrusion
• Optimized for quick assembly with a coarse M10x1.5mm thread and Class 5g6g fit, ensuring easy engagement and consistent clamping force
• Guaranteed dimensional consistency and interchangeability by conforming to the stringent DIN 916 metric standard
• Safe for use in regulated environments as it is fully compliant with RoHS 3 and REACH environmental directives
• Versatile headless design that saves space and provides a flush finish in assemblies where clearance is limited

Professional Applications & Engineering Value

This M10 x 1.5mm headless set screw is engineered to solve critical challenges in precision machinery and industrial equipment. The alloy steel material, hardened to Rockwell C45, provides the necessary tensile strength to resist vibrational loosening and maintain clamp load in high-stress applications. The cup point design creates a permanent indentation on the shaft, effectively locking components like gears, pulleys, and collars in place without the need for additional fasteners. Its headless and hex drive configuration is ideal for confined spaces, allowing for a clean profile and tool access in complex assemblies. Meeting DIN 916 specifications, this metric set screw ensures reliable performance in automated systems, automotive components, and heavy-duty manufacturing fixtures where precision and repeatability are paramount.

Specification Summary & Compliance

This set screw features an M10 metric coarse thread with a 1.5mm pitch and a Class 5g6g thread fit, providing standard manufacturing tolerances for reliable engagement. It is manufactured in compliance with the DIN 916 standard, ensuring dimensional accuracy and performance consistency. The product is also confirmed to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, adhering to strict environmental regulations for hazardous substances.
