The Unifix A2-70 Socket Button Head Screws (M6 x 50) are ideal for DIY enthusiasts and professionals seeking a reliable, low-profile fastening solution for metal-to-metal or metal-to-wood projects. These high-quality stainless steel screws provide exceptional corrosion resistance and a clean, flush finish, making them perfect for aesthetic-focused assemblies; however, users should ensure they have the correct size hex key, as the socket head requires specific tooling to prevent stripping.

A2 refers to the grade of stainless steel (304), known for good corrosion resistance. The 70 indicates a tensile strength of 700 N/mm2.
Yes, A2-70 stainless steel is highly resistant to rust and suitable for most outdoor applications, though it may show surface staining in heavy marine or high-salt environments.
These are metric screws with an M6 thread diameter.
The head follows ISO 7380-1 standards, which typically results in a head diameter of 10.5mm.
No, these are individual screw fasteners and do not include nuts or washers unless specified in a bundle.
Apply a stainless steel-compatible anti-seize lubricant or general thread lubricant to the threads before installation.
This is often due to 'galling' caused by stainless steel friction. Back the screw out, add a small amount of lubricant, and tighten at a slower speed.
Check that you are using the correct size hex wrench. If the tool is worn, replace it to ensure full surface contact with the socket walls.
While the screw can be cut down, ensure you clean the threads after cutting so it can be threaded into the nut or tapped hole without damage.
For optimal results, use a high-quality M6 hex key or a hex bit driver that fits snugly into the socket to avoid damaging the head. If installing into hard materials, consider applying a small amount of anti-seize lubricant or wax to the threads to prevent binding. Ensure your mating surfaces are clean and aligned before driving the screw home. Store these screws in a dry, organized container to prevent cross-contamination with carbon steel fasteners, which can cause surface rust on stainless steel over time.
