Screws For Aluminum Studs
Weight Range ： 0.5g–500kg
Dimensional tolerance ： ±0.1mm
"Please provide product specifications so that we can offer specific pricing and MOQ."
Screws for aluminum studs are specially developed for joining aluminum alloy profiles. The thread angle is designed to be 60 degrees. This angle increases the contact area with the aluminum. Based on tensile test data. M6 size screws on 2.5mm thick aluminum. The breaking torque reaches 5.5 Nm. This is far beyond the output range of conventional electric drills. Make sure the connection points have sufficient safety margin. The surface coating thickness is controlled between 8 and 12 microns. Can cover thread sharp corners. It will not increase the screwing resistance due to excessive thickness.
This type of screw causes minimal damage to the base material. After drilling, the hole diameter is only 0.2 mm larger than the screw diameter. Will not damage the structural strength of the profile. Actual measurement data is displayed. Double-layer aluminum panels connected using special screws. After 200 hours of salt spray testing. The residual torque still maintains more than 90% of the initial value. The tail of the screw is specially hardened. It can continuously drill through multi-layer aluminum profiles with a total thickness of 20 mm. No need to change drill bits during the entire process.

Advantages
► Reliable tensile strength
The degree of engagement between the screw and the aluminum determines the stability of the connection. Take the M5.5x25mm specification as an example. High quality product on 1.5mm thick aluminum alloy base material. Its ultimate pull-out force exceeds 2.2kN. This means that a single screw can withstand a static pulling force of approximately 220 kg. It can ensure that the suspended ceiling keel does not fall off. Heavy equipment mounts won't come loose due to gravity, either.
► Adapt to profiles of different thicknesses
Architectural aluminum profiles vary in thickness. The thin-walled auxiliary keel is only 0.8mm. The main stress-bearing column can reach 3.0mm. Users can choose different tail models. Such as F25 or F32 models. High-quality screws are suitable for penetration of total thickness up to 12mm. For example, SD5-32 type screws. It can penetrate two layers of 1.5mm aluminum plates. Add another layer of 2.0mm connectors. There is always enough allowance at the tip of the screw. Make sure the threads are fully formed.
► Improve the fitting accuracy of curved surfaces
Curved aluminum alloy columns are commonly used in modern buildings. There are ball washers under the screw heads. Its extra large washer surface has a diameter of 11mm. This design allows the screws to be offset from the board surface. The maximum deflection angle can reach ±3°. Test data proves it. When tightened, the gasket can fit the curved surface 100%. It provides even compression. Avoid local stress concentration on aluminum alloy panels. Prevent panels from deforming or cracking.
► Adapt to anodized surface requirements
There is an anodized film on the surface of aluminum alloy profiles. This membrane is insulating and hard. The tip angle of high-quality self-drilling screw drills is 108° to 120°. It has an auxiliary cutting edge. Penetration test proven. It can effectively penetrate 20μm thick oxide film. The drill tail will not chip. The thread opens the film layer. Make sure the screws are in direct contact with the base metal. Form a reliable conductive path. A solid mechanical bite is achieved.
why choose us
★ Support accurate cost accounting
- Each box of screws is marked with plate thickness and quantity. Budgeters can accurately calculate usage. The material loss rate dropped from 12% to less than 7%.
★ Suitable for building renovation projects
- The surface hardness of old aluminum materials varies greatly. Ordinary screws slip easily. Special screw drill tail hardness output is stable. The rework rate of renovation projects was reduced by 25%.
★ Compatible with smart machine operations
- Assembly robots have high requirements on screws. The torque fluctuation of special screws is less than ±0.8N·m. The robotic arm tightening success rate reaches 98.3%.
★ Reduce the amount of tools you carry
- The working space of aerial vehicles is limited. Special screws only require an electric drill. Tool kit reduced from 5 pieces to 2 pieces. The risk of falling is reduced by 40%.
