Stainless Steel Hex Socket Set Screws with Cup Point DIN916
Product Overview
Hex Socket Set Screws with Cup Point are a widely used threaded fastener designed for precision and secure applications. Manufactured in compliance with DIN916 standards, these set screws feature a cup-shaped point that embeds firmly into mating surfaces, helping resist loosening due to vibration or torque. These screws are commonly made from austenitic stainless steel, offering superior corrosion resistance and durability.
Ideal for mechanical assemblies, precision engineering, and equipment where secure axial fixing is critical, Hex Socket Set Screws are an indispensable fastening solution in various industrial domains.

Material and Manufacturing Process
Hex Socket Set Screws with Cup Point are typically manufactured from high-quality stainless steel grades such as A2 (304) and A4 (316). A2 stainless steel offers good corrosion resistance in dry indoor environments, while A4 stainless steel provides enhanced resistance in marine or chemical processing applications.
Manufacturing Process Includes:
- Cold heading or thread rolling for forming the screw blank.
- Heat treatment for required mechanical properties and hardness.
- Precision machining to create the hex socket and cup point end.
- Surface finishing such as passivation to enhance corrosion protection.
- Inspection and packaging.
This process ensures optimal thread engagement, tight dimensional tolerances, and consistent performance in demanding applications.
