You want your building projects to stay strong for a long time. When you pick a bi metal screw, you get more than just a regular fastener. Many builders trust bi metal screws because they go into steel fast, do not rust in bad weather, and stay strong when holding heavy things. Regular screws do not give you this mix of strength and safety. People use these screws in solar panels, steel roofs, and metal frames. Jiaxing Haina Fastener Co., Ltd. promises good quality, so you can feel sure with every screw.
Bi metal screws have a hard steel tip and a stainless steel shaft. They are strong and last a long time. These screws do not rust easily. This makes them good for tough places like near the ocean or in chemical plants. The self-drilling tips help you put them in fast. You do not need to drill holes first. This saves time and money on work. Bi metal screws can hold heavy things well. They are used in many jobs, like building, boats, and solar panels. Using these screws makes less waste. It also makes the work site safer by needing fewer tools and steps.
You want your projects to last a long time. You need fasteners that do more than just hold things. A bimetal screw uses two metals for better results. The steel tip is very hard and cuts through tough stuff easily. The stainless steel shaft does not rust, even in bad weather. This smart design helps you put screws in fast and keeps them strong for years.
Here’s how bimetal screws and traditional fasteners are different:
Aspect | Bi-Metal Screws | Traditional Fasteners |
|---|---|---|
Material Composition | Combination of SUS 304/316/316L Stainless Steel and Alloy Steel SMC 435 | Typically C1022A and SUS 410 |
Corrosion Resistance | High, enhanced by RUSPERT coating | Lower corrosion resistance |
Mechanical Strength | High toughness and strength due to hybrid materials | Lower durability and strength |
Surface Treatment | RUSPERT coating for superior corrosion protection | Generally no advanced coating |
Application Suitability | Ideal for harsh environments like coastal, chemical, and transportation hubs | Less suitable for demanding environments |
A bimetal screw has a stainless steel shaft that fights rust. Its strong tip makes drilling easy. This mix helps the screw work with many materials and keeps your project safe.
Bimetal screws are stronger and last longer than regular ones. The stainless steel shaft stops rust, so the screw stays strong in wet or salty places. The steel tip lets you put the screw into metal, wood, or other materials without problems. You will not have weak or rusty screws.
A bimetal screw is special because it uses the best parts of both metals. The stainless steel shaft lasts a long time. The steel tip gives you the power to do hard jobs. This design keeps your project safe and working well. You get a screw that works hard and does not break, so you save time and money.
Tip: If you need a screw for tough jobs or bad weather, pick a bimetal screw with a stainless steel shaft. You will see it lasts longer and works better.
You want your projects to last, even when the weather is bad or the air is salty. Bimetal fasteners help you in these tough places. A bimetal screw has a stainless steel shaft and a hard steel tip. This mix helps stop rust and damage from water, salt, and chemicals.
Bimetal screws work well in places with lots of moisture or chemicals.
The stainless steel shaft stops rust, so you do not get weak spots.
The steel tip lets you drill into hard things and keeps its strength.
You get a fastener that holds tight, even when rain, salt, or chemicals try to break it.
Note: Galvanized fasteners can lose their coating after a while, especially near the ocean or in places with lots of chemicals. Bimetal screws have a stainless steel core, so they keep working long after other fasteners stop.
You can trust bimetal screws in buildings near the sea, chemical plants, and outdoor places. They help you avoid expensive repairs and keep your work safe.
When you pick bimetal fasteners, you get long-lasting results. These screws do not just last—they do well in tough places. The stainless steel shaft fights rust, so your fasteners stay strong for many years.
You do not have to worry about rust making your connections weak.
The bimetal design means you do not need to fix or change them often.

A table can help you see the difference:
Fastener Type | Corrosion Resistance | Durability in Harsh Environments | Maintenance Needs |
|---|---|---|---|
Bimetal Screw | Excellent | High | Low |
Galvanized Fastener | Moderate | Medium | Medium |
Stainless Steel | Superior | High | Low |
You want to build and feel sure about your work. Bimetal screws give you that feeling. Their strong resistance to rust protects your work and keeps your buildings strong. You save time, money, and effort by using fasteners that last.
Tip: For jobs in wet, salty, or chemical-heavy places, always use bimetal screws. You will notice they are stronger and last longer.
You want to finish your projects quickly and with less effort. Bi metal screws help you do just that. These screws have a sharp point and a strong tip. You do not need to drill a pilot hole first. You can drive the screw straight into metal or wood. This saves you time and energy.
Bi metal screws support a driver speed of up to 1800 R.P.M.
Traditional screws only allow about 800 R.P.M.
You can install bi metal screws more than twice as fast as regular ones.
Tip: Self-drilling screws combine drilling and fastening in one step. You skip the extra work of making pilot holes.
Here is how the process works:
Place the screw where you want it.
Use your drill to drive it in.
The screw drills and fastens at the same time.
Field data shows you can cut installation time by over 60% with self-drilling screws. A job that takes 8.5 seconds with a regular screw only takes about 3.2 seconds with a bi metal screw. You finish your work faster and move on to the next task.
You want to save money and reduce hard work on every project. Bi metal screws make this possible. Their design lets you use one tool for both drilling and fastening. You do not need extra equipment or extra steps. This means fewer tools, less clutter, and less time spent on each job.
Combined drilling and fastening reduce installation steps.
Single-tool operation lowers equipment needs.
No extra parts needed, so you spend less on materials.
Simple process means fewer labor hours.
Projects finish faster and safer.
Bi metal screws offer a cost-effective alternative to traditional fasteners. You can save between 30% and 50% on labor costs because you skip many steps. In large construction projects, these screws help you manage your budget better. You also avoid extra costs from material damage or rework. The result is a cleaner, faster, and more reliable installation.
Note: When you use bi metal screws, you get strong, fast, and safe results. You also keep your project on schedule and under budget.
