The “M” indicates that it’s a metric screw, while “8” refers to the nominal diameter of the screw in millimeters (8 mm). The “1.25” is the pitch of the thread, meaning the distance between threads is 1.25 mm. Knowing this helped me ensure compatibility with my applications.

In my search, I discovered various types of M8 x 1.25 fasteners, each suited for different applications:
- Bolts: Perfect for heavy-duty applications, I found that M8 bolts are often used in structural assemblies.

- Screws: M8 screws are versatile and can be used in wood, metal, or plastic. I personally found socket head cap screws very useful in my projects.
Materials Matter
The material of the fastener can significantly impact its performance and durability. Here are the options I considered:
- Steel: This is the most common material. I found that galvanized or zinc-coated steel provides good corrosion resistance.
- Stainless Steel: For projects exposed to moisture, I opted for stainless steel fasteners for their superior rust resistance.
- Aluminum: Lightweight and resistant to corrosion, I used aluminum M8 fasteners for specific applications where weight was a concern.
Coating Options
When I looked into coatings, I discovered that they can enhance durability and resistance:
- Zinc Plated: This coating provides decent corrosion resistance, which I found suitable for indoor applications.
- Black Oxide: I appreciated the sleek appearance and moderate corrosion resistance for certain projects.

Price Considerations
In my experience, prices for M8 x 1.25 fasteners can vary widely based on material, coating, and quantity. I found bulk purchases to be more economical, but I always weighed the price against my immediate needs and project scope.
Final Thoughts
