Bolt, Hexagon Socket Head

Damaged radiators are never easy to repair, even by professionals. The results can be patchy and quite often lead to more leaks later, or worse, blockages!
Lime deposits are also difficult to remove and reduce the efficiency of the radiator markedly.
Sometimes the best option is simply to renew the radiator and as many of the ancillary items as you can afford, although expensive, it is a lot less than the damage caused by an overheating engine!
