Large Head Stainless Steel Screws
Weight Range ： 0.5g–500kg
Dimensional tolerance ： ±0.1mm
Large head stainless steel screws are a reliable choice for harsh environments. It has excellent carrying capacity. The tensile strength of a single screw exceeds 800 MPa. Can support several tons of pressure. It is made of high-quality 316 material. Can pass salt spray test for up to 96 hours. This ensures long-term stability in humid or corrosive environments. Significantly reduces maintenance frequency and costs.
It performs equally well under dynamic loads. The enlarged head design improves anti-loosening performance. In the vibration test, its pretightening force retention rate is more than 30% higher than that of ordinary screws. In addition, it can adapt to a wide temperature range. The working range ranges from minus 200 degrees Celsius to over 650 degrees Celsius. Performance does not degrade significantly. Therefore, it is widely used in key fields such as rail transportation, energy equipment, and high-temperature pipelines.

Drawing Design & Confirm
Obtain drawings from clients or produce drawings based on their samples or specifications.
The drawings, product raw materials, surface treatment, and other details are attested to by both parties.
Advantages
Extremely high structural integrity
Superior large head stainless steel screws with superior mechanical qualities. For instance, the tensile strength of A4-80 (316 material) is greater than 800 MPa. Because of this, a single M10 screw can endure a static pulling force of about five tons.
Pressure is dispersed over a greater area by the large head. This keeps the connector's surface from being compressed. It works especially well on structural steel beams and heavy machinery.
Excellent anti-vibration performance
The screws can be effectively kept from loosening thanks to the large head design. The connecting surfaces are under less pressure thanks to the bigger head. This lessens the preload loss brought on by material creep.
According to vibration tests, its preload retention rate is over 30% greater than that of conventional screws after a million cycles. Bridges, generators, and railroads all depend on this feature.
Good surface compatibility
These screws have an electropolished or passivated surface. It may have a surface roughness of less than 0.4 microns. Dirt and bacteria are less likely to stick to smooth surfaces.
It can withstand a variety of cleaning agents. As a result, it can satisfy FDA and other health certification requirements. extensively utilized in high-end kitchenware, medical equipment, and food machinery.
Optimized weight to strength ratio
The use of thinner screws with equivalent strength is made possible by the large head design. An M8 large head screw, for instance, can take the place of an M10 standard screw.
A single piece's weight can be decreased by roughly 20% in this way. This can successfully reduce weight without compromising safety in industries like precision instruments and aerospace.
why choose us
-
The sealing performance is reliable
- The large head is used for pipe flange connections, uniformly compresses the gasket, and can sustain 1.6 MPa pressure without leaking.
-
Installation is more convenient
- The preset alignment accuracy is improved by about 40%, and the large head offers substantial visual reference. This can significantly reduce assembly time and is particularly useful in situations involving batch or space-constrained installations.
-
Broad compatibility
- The galvanic corrosion rate is less than 5 microns per year when its passivated surface comes into contact with aluminum alloys, composite materials, etc. appropriate for a range of materials' hybrid connection structures.
