The Unifix Grade 10.9 Socket Button Head Screws are high-strength fastening solutions designed for professional mechanics, engineers, and DIY enthusiasts requiring reliable, heavy-duty hardware. These screws offer exceptional tensile strength for demanding assemblies, though users should ensure they are using the correct hex key size to avoid stripping the socket during high-torque applications.

The 10.9 rating refers to the mechanical properties of the steel, specifically its high tensile strength and yield strength, making it ideal for heavy-duty industrial fastening.
They are zinc-plated for enhanced corrosion resistance, which protects against surface rust in normal environments. They are not stainless steel and should be monitored in highly corrosive or saltwater environments.
Yes, Grade 10.9 is a common standard for automotive components where high-strength steel is required to withstand vibration and mechanical stress.
These use a hex socket drive, requiring a standard metric hex key (Allen wrench).
If the threads are not deformed and the socket head is not stripped, they can generally be removed and reused in similar applications.
This product comes in a box of 200 pieces.
The socket is likely stripped. Ensure you are using the correct metric size hex key and that it is fully seated in the socket before applying torque.
Check the threads of the mating hole for debris or cross-threading. If the hole is clear, try using a small amount of lubricant on the screw threads.
To install these screws, ensure you are using a high-quality hex key that matches the socket size precisely. For best results, clean the threaded holes of any debris or old thread-locking compound before insertion to prevent cross-threading. While the bright zinc finish offers good protection, avoid using abrasive cleaning pads that could scratch the coating and expose the raw steel to moisture. If you are using these in outdoor or high-humidity applications, periodically inspect them for signs of surface oxidation and consider applying a light machine oil if the environment is particularly harsh.
