"I purchased 6x M10x220mm cap heads. They took a week and 2 days to come which was cutting it a bit fine for our deadline. When they did come, all 6 cap heads were bent to the point were they wouldnt fit through the engine they had to go through. Unfortunately because we were so close to our deadline, we had to straighten them to use them. Not impressed with the quality of product, won't be using them again if i can help it."
