Carbon Steel Hex Socket Flat Point Set Screws
Product Overview
Hex socket flat point set screws are precision-engineered fasteners used to secure an object within or against another object without protruding beyond the surface. Designed with a headless cylindrical body and a hexagonal socket drive, these set screws feature a flat point that provides stability without damaging the mating surface. Manufactured from high-quality carbon steel, these screws are heat-treated for durability and strength. They offer a reliable, discreet locking method in mechanical components and instrumentation assemblies.
These screws are essential in applications requiring flush installations and high torque retention, such as fixing gears, pulleys, and collars to shafts. Their minimal projection design makes them ideal for use where aesthetics or space limitations are crucial.

Material & Manufacturing Process
Hex socket flat point set screws from Flybear Fastener are crafted from high-grade carbon steel, which provides a perfect balance of strength, ductility, and cost-efficiency. The raw material is subjected to precision machining, including cold heading and thread rolling. Post-forming, the screws undergo heat treatment to achieve the desired mechanical properties and wear resistance.
The surface treatment options include black oxide and zinc plating, which enhance corrosion resistance while maintaining a clean, sleek appearance. Each batch of screws is meticulously inspected to ensure tight tolerance control and flawless threading.
Typical Applications & Industry Use Cases
Flat point set screws are widely utilized in:
- Automotive assemblies such as locking collars and synchronizer rings
 - Industrial machinery and gearboxes
 - Electronic housings and instrument enclosures
 - Robotics and automation systems
 - Aerospace components where minimal surface interference is critical
 - Marine equipment with zinc-plated variants providing reasonable corrosion resistance
 
They are especially favored in scenarios where the screw needs to be fully embedded below the outer surface, offering both security and a clean appearance.
