Carbon Steel Hex Socket Cup Point Set Screws
Product Overview
Hex socket cup point set screws are critical components in modern mechanical assemblies, particularly where secure, flush fastening is required. These set screws feature a hexagonal recessed drive (also known as an Allen socket) and a cup-shaped point that penetrates the contact surface to provide firm gripping without damaging the mating part. Manufactured from high-quality carbon steel, they are widely recognized for their high tensile strength, resistance to wear, and optimum holding power under vibration or dynamic stress.
Designed for precision fits and strong torque transmission, these fasteners are key in applications demanding secure locking in rotary elements. Whether for machinery, automotive components, or electronics, hex socket cup point set screws deliver reliable performance and extended lifespan.

Material and Manufacturing Process
Our hex socket cup point set screws are manufactured from high-grade carbon steel, chosen for its balance of strength, machinability, and cost-efficiency. The production process includes:
- Raw Material Selection – Only certified carbon steel is selected.
- Cold Heading – For forming the screw heads and threads precisely.
- Thread Rolling – Threads are formed with dies, ensuring strength and dimensional accuracy.
- Heat Treatment – For achieving the desired hardness and tensile strength.
- Surface Treatment – Finishing processes like black oxide or zinc plating for enhanced corrosion resistance.
This manufacturing process ensures that every screw meets international performance and safety standards.
