Stainless Steel Self Drilling Screws For Metal
Weight Range ： 0.5g–500kg
Dimensional tolerance ： ±0.1mm
Thickness ： 1mm-100mm
Stainless steel self drilling dcrews for metal are fasteners designed specifically for metal connections. It is made of high-strength stainless steel material. Product size tolerance is strictly controlled at ±0.1mm. This ensures installation accuracy. Standard lengths range from 10mm to 100mm. If special sizes are required, JOYEAR provides professional customization services. JOYEAR can meet your individual needs.
This screw has excellent performance. Its tensile strength exceeds 700MPa. It can drill directly through 2.5mm thick steel plate. The surface is professionally passivated. It passed 500 hours salt spray test. Corrosion resistance far exceeds that of ordinary fasteners. The unique drill tail design enables drilling and tapping to be completed in one go. Compared with traditional methods, it saves about 80% of operating time. These advantages make it ideal for building curtain walls and industrial equipment. It significantly improves engineering efficiency. At the same time, maintenance costs are effectively reduced.
Drawing Design & Confirm
Obtain drawings from clients or produce drawings using their samples or specifications.
Both parties attest to the drawings, product raw materials, surface treatment, and other specifics.
Benefits
Strong mechanical properties and gripping force
High-quality stainless steel self-drilling screws with excellent mechanical properties. Its performance level is A2-70 or A4-80. This means that the tensile strength reaches 700 MPa and 800 MPa respectively. The screws are designed with self-tapping threads.
It cuts matching threads into the base material. This creates strong clamping force. Tests have shown that the pulling force of a 5.5mm screw can reach thousands of Newtons. It ensures that the connection points are strong and durable. It effectively resists vibration and shear forces.
Wide material adaptability
With its hardened drill tip (hardness can reach over HRC 50), stainless steel self-drilling screws can easily penetrate a variety of materials. For example, a screw with a #3 drill bit can effectively drill through 1.0 to 2.0 mm thick mild steel plate; a #5 drill bit can handle substrates exceeding 3.0 mm.
It can not only be used to connect metal plates of various specifications (such as color steel plates, aluminum plates), but can also be successfully fixed to light steel keels, wood and metal composite structures, etc., showing excellent versatility.
Material uniformity to eliminate galvanic corrosion
Since the screws and the connected metal base materials (such as stainless steel plates, aluminum materials) are corrosion-resistant materials, or are separated by coatings, electrochemical corrosion caused by contact of dissimilar metals is fundamentally avoided.
Actual measurement data shows that in a salt spray environment, the galvanic corrosion rate of the A4-80 stainless steel screw-platesystem with unified materials is more than 95% lower than that of the carbon steel screw-aluminum plate combination, effectively extending the structural life from 3-5 years to more than 20 years, and is especially suitable for ships and chemical equipment.
Enhanced protection by surface passivation treatment
High-quality stainless steel self-drilling screws will undergo strict passivation treatment to make the chromium oxide protective film on the surface more dense and uniform.
According to the ASTM B117 standard, the time for passivated screws to first appear red rust in the neutral salt spray test can be extended to more than 500 hours, and their corrosion resistance is more than 30% higher than that of similar products without treatment.
This protective film can also effectively resist fingerprints and other pollutants, keep the product beautiful, and meet application scenarios with extremely high hygiene requirements such as medical devices and the food industry.
