The Unifix A2-70 Socket Head Cap Screws are ideal for both DIY enthusiasts and professional contractors who require reliable, high-strength fastening solutions. Engineered for durability and corrosion resistance, these M6 x 30 screws feature a socket head design that facilitates installation in tight or recessed spaces. While these fasteners are highly versatile and durable, users should ensure they are using the correct hex key size to prevent stripping the screw head during installation.

A2 refers to the grade of stainless steel (304), known for good corrosion resistance, and 70 indicates the tensile strength of the fastener.
Yes, the A2-70 stainless steel provides excellent resistance to most weather conditions, though it is not recommended for direct salt-water submersion.
You will need a standard metric hex key (Allen key) compatible with M6 socket head screws.
Yes, but use a low-torque setting and a proper hex bit to avoid over-tightening or stripping the socket.
No, this product is the box of 200 screws only.
The screw length is 30mm, measured from under the head to the tip.
Check the hole for debris or cross-threading; do not force the screw as this may damage the threads.
Verify that you are using the correct metric hex key size and that the tool is not worn out.
For optimal results, ensure that the threaded hole is clear of debris before insertion. Use an appropriately sized high-quality hex key to drive the screw, applying steady, even pressure to avoid cam-out. Because these are A2-70 stainless steel, they are compatible with standard stainless steel nuts and washers. To maintain their appearance and structural performance in outdoor or coastal environments, occasionally clean them to remove salt or chemical buildup. Keep the remaining stock in the original box to prevent thread damage and cross-contamination with other metal types.
