Stainless Steel Hex Socket Flat Thin Head Drilling Screws
Hex Socket Flat Thin Head Drilling Screws are precision-engineered fasteners ideal for flush surface applications where both strength and aesthetics matter. These screws are designed with a thin flat head for countersunk finishes and an internal hex drive that offers excellent torque transmission. The self-drilling tip allows direct penetration into metal without pre-drilling, making them highly efficient in time-sensitive installations.
At Flybear Fastener, we manufacture and supply high-quality stainless steel Hex Socket Flat Thin Head Drilling Screws tailored for industrial and construction needs.
Product Overview
Hex Socket Flat Thin Head Drilling Screws are specialized self-drilling screws made of high-grade stainless steel. They are designed for fastening metal panels and other materials where a flush surface is required after installation. The internal hex drive provides increased tightening torque without stripping, while the self-drilling point eliminates the need for pilot holes.
These fasteners are extensively used in applications demanding corrosion resistance, sleek finishes, and strong mechanical connections.

Material and Manufacturing Process
Our Hex Socket Flat Thin Head Drilling Screws are made from premium stainless steel grades such as SS304 and SS316, ensuring excellent oxidation and corrosion resistance. Stainless steel is especially suitable for exterior-use fasteners due to its longevity and minimal maintenance.
The production process includes:
- Precision cold forging of the screw head and body
- Thread rolling to achieve tight tolerances
- Heat treatment for enhanced mechanical properties
- Self-drilling point formation
- Surface cleaning and optional passivation or coating
- Final inspection and packaging
Each step is carefully monitored to meet international standards and ensure reliable and consistent product performance.
Applications in Multiple Industries
These stainless steel drilling screws are commonly used in:
- Metal roofing and siding installations
- HVAC ductwork and assemblies
- Automotive and aerospace subassemblies
- Electrical enclosures and panel fixing
- Interior architecture and cabinetry requiring flush fastenings
- Marine environments due to elevated corrosion resistance
