The Unifix Grade 12.9 Socket Shoulder Screws are precision-engineered fasteners designed for engineers, fabricators, and DIY enthusiasts who require high-strength mechanical components for pivoting or sliding applications. These screws offer exceptional structural integrity and reliable performance under heavy loads, though users should ensure their project specifications align with the 10mm (M8) shoulder dimension and ISO 7379 standards before installation.

These screws are made from Grade 12.9 alloy steel, which is a high-tensile strength material.
No, these are high-strength alloy steel screws and do not possess the corrosion resistance of stainless steel.
The 10mm dimension refers to the diameter of the precision-ground shoulder portion of the screw.
Yes, they are manufactured to meet ISO 7379 standards.
Due to the steel composition, they are best suited for indoor or controlled environments. Use in exterior applications may lead to surface oxidation.
This specific product (MPN 1264356) is supplied in a box of 50.
Verify that the hole is properly reamed and free of debris; ensure the shoulder diameter matches the mating component's bore.
Ensure you are using the correct metric hex key size and that the key is fully inserted into the socket head.
To install, ensure the hole in your workpiece is drilled and reamed to the appropriate tolerance for the 10mm shoulder. Using a high-quality hex wrench, tighten the screw until the shoulder is fully seated against the mating surface.
Compatibility is determined by the M8 thread size and the 10mm shoulder diameter. Ensure you are using the correct thread pitch for your tapped holes. To maintain these screws, keep them in a dry environment and apply a thin layer of machine oil if the assembly is subject to high-friction movement, as this prevents wear on the shoulder surface.
