M12 X 85 Through Bolts A2 Stainless Steel (304)

A2 through-bolts are used for heavy-duty fixing in materials like concrete and solid brick, especially where corrosion resistance is needed, such as for outdoor and marine applications. Common uses include fixing brackets, railings, park benches, and metal structures, particularly in construction where safety and stability are critical. They are also ideal for attaching awkward fixtures without having to remove them for marking and repositioning.
