The Unifix Grade 10.9 Socket Button Head Screws are designed for DIY enthusiasts and professional builders who require high-strength, reliable fastening solutions for metal-to-metal or heavy-duty mechanical assemblies. These screws offer exceptional tensile strength and a corrosion-resistant finish, making them ideal for long-term structural integrity, though users should ensure they have the appropriate hex key drive size to avoid stripping the socket during high-torque applications.

Grade 10.9 indicates the tensile strength of the steel. It is a high-strength fastener, meaning it can withstand 1,000 MPa of tensile stress, making it ideal for heavy-duty applications.
While the silver finish provides some rust resistance, these are not stainless steel. They are best suited for indoor use or protected, dry outdoor environments.
These are socket button head screws, which have a rounded, low-profile top that provides a neat appearance while offering enough depth for the hex drive.
No, these screws are designed to be used with pre-tapped or threaded holes. They are not intended to cut their own threads into raw material.
No, the pack contains only the screws. You will need to provide your own hex key or drive tool of the corresponding size.
Ensure your hex key is not worn down and is the correct metric size. Use steady manual pressure before applying full torque.
Verify the thread pitch of your tapped hole matches the screw. Do not force the screw if it meets resistance; remove and check for debris in the hole.
Installation requires a high-quality hex key or an Allen bit that matches the screw socket size perfectly. To ensure the longest lifespan, avoid using power tools with excessive torque settings, as this can damage the internal drive. It is recommended to apply a small amount of machine oil to the threads if you are fastening into rusted or tight-tolerance tapped holes to reduce friction. Keep the screws in a dry environment to maintain the integrity of the silver finish. Periodically check fasteners after the initial assembly of heavy-vibration equipment to ensure they remain at the proper torque specification.
