Metric Flat Point Socket Set Screws, 45H Iso 4026 / Din 913, Thermal Black Oxide, Alloy
Metric flat point socket set screws are manufactured to ISO 4026 / DIN 913 standards and hardened to 45H for superior strength and reliability. These fasteners feature a smooth, flat‑ended tip engineered to apply uniform pressure without penetrating or scoring the mating surface—making them ideal for applications requiring repeated adjustments, precision alignment, or gentle clamping.
Constructed from high‑strength alloy steel and treated with a thermal black oxide finish, these screws offer enhanced wear protection, improved lubricity, and a clean, low‑glare black appearance. The internal hex (Allen) drive provides dependable torque transmission and easy installation in tight or recessed areas.

Metric 45H alloy flat point set screws are widely used in mechanical assemblies, machinery maintenance, and OEM production where non‑marring surface contact is essential. The flat tip distributes pressure evenly across the surface, making them suitable for securing collars, gears, pulleys, and components on shafts or rods without causing damage.
The thermal black oxide coating provides added resistance to oxidation and wear, ensuring long service life in industrial environments. Available in a broad selection of metric diameters and lengths to meet precise engineering specifications and manufacturing requirements.
