Metric Sizes Cup Point Black Oxide 45H ISO 4029 DIN 916 Socket Set Screws

Metric cup point socket set screws, finished in black oxide and manufactured to ISO 4029 / DIN 916 standards, are precision-engineered for secure, flush fastening in high-performance metric applications. These 45H hardened alloy steel fasteners deliver exceptional strength and wear resistance, making them ideal for use in mechanical assemblies, automotive systems, industrial machinery, and precision equipment.

The cup point design provides a concave tip that grips the mating surface securely without excessive material deformation, delivering reliable holding power for securing shafts, collars, pulleys, gears, and rotating components. This makes them ideal for both permanent and adjustable setups, where alignment and vibration resistance are key.

The black oxide finish offers mild corrosion resistance and a low-reflection, professional appearance, making these screws well-suited for both functional and visible installations. It also improves lubricity for smoother torque application and easier installation.

Manufactured to ISO 4029 / DIN 916 standards, these screws include a hexagonal socket drive and a cup point tip for consistent engagement, torque control, and secure positioning.
