M3 x 100 M4 x 100 M5 x 100 M6 x 100 M8 x 60 Often called split lock or split ring washers, spring washers are locking washers that prevent a fastener from loosening as a result of vibration. They have a split in the washer section that when tightened each side of the split bites into the nut and the mounting surface. This prevents any anti-clockwise rotation from occurring under vibration. Spring washers are usually used on the nut side of the fastener. These are the 'square section' type which refers to the end section of the split in the washer, which in this case is square. This set contains a selection of of M3, M4, M5, M6 and M8 (3mm, 4mm, 5mm, 6mm & 8mm internal diameter) washers. A2-70 stainless steel, also known as 304 or 18/8 grade has great weather resistance and longevity. It can be used in all outdoor conditions apart from where consistent exposure to either salt water or sewerage is expected. Complements other M3 – M8 kits and a useful addition to the toolbox.
