M8 refers to the 8mm diameter of the bolt thread, and 20 indicates the length of the shank in millimeters.
No, these are designed specifically for tool-free, hand-tightened operation.
They feature a bright zinc plating which provides good corrosion resistance, but they are not stainless steel and should be kept away from harsh, wet, or saltwater environments.
No, these are intended for furniture, cabinetry, and light machinery adjustments, not for structural load-bearing connections.
Yes, the Unifix range includes various diameters and lengths such as M6 and other M8 variations.
Ensure the threading matches the M8 size. If it is a new hole, verify the thread pitch is compatible.
Check that the shoulder is properly seated against the surface and that the fastener is not being asked to support more weight than its design capacity.
To ensure proper installation, clear the threaded hole of any debris or old sealant before inserting the screw. Simply align the screw with the hole and turn clockwise by hand until firm. Do not overtighten using pliers or mechanical tools, as this may strip the threading or damage the shoulder. Keep the threads clean and dry; if the environment is highly humid, consider applying a light machine oil to the threads to maintain ease of movement.
