The Unifix Grade 10.9 Socket Button Head Screws are high-strength fasteners engineered for professionals and DIY enthusiasts requiring reliable, heavy-duty hardware for machinery and structural assemblies. These screws offer superior tensile strength due to their 10.9 grade steel composition, ensuring secure fastening in demanding environments; however, users should note that the socket button head requires a specific hex-key drive, which may limit compatibility with standard Phillips or flathead tools.

The 10.9 rating indicates the mechanical properties of the steel, specifically that it has a tensile strength of 1000 MPa and a yield point of 900 MPa, suitable for high-stress applications.
No, these are high-strength alloy steel screws with a silver-colored finish; they are not classified as stainless steel and should be kept away from harsh corrosive environments.
You need a standard metric hex key (Allen key) that fits the specific socket size of your screw diameter.
Due to the steel composition, they may develop surface rust if exposed to rain or high moisture; for outdoor use, stainless steel fasteners are generally preferred.
These listings typically refer to the screws only; please check your specific package contents to confirm if nuts or washers are included.
Yes, as long as the threads are not stripped and the hex socket remains in good condition, they can be reused for multiple assembly cycles.
Verify that you are using the correct metric hex key size and that the key is not worn down.
Check the thread pitch match; ensure there is no debris or paint residue in the receiving hole.
Ensure the screw is perfectly perpendicular to the surface and use a manual torque-limiting tool.
To install, select an appropriately sized metric hex key corresponding to your screw diameter. Ensure that the mating material is pre-drilled and threaded to match the screw's ISO 7380-1 specifications. While these screws are durable, they are not inherently stainless steel; therefore, it is advisable to keep them in dry storage to prevent surface discoloration. If used in a high-vibration environment, consider adding a thread-locking compound to the threads to maintain bolt tension over time. Clean with a light machine oil if necessary to maintain the silver finish and prevent superficial oxidation.
