Some suppliers keep their nuts, bolts, and screws in loose form. Frankly, we think this is disasterous. Why? The sizes and types get hopelessly mixed up. You get M6 M8 mixed together for example, you get countersunk and cheese head mixed up. You can never be sure you are getting 304 or 316 grade screws. The bin for the screws you want will be empty as the shop assistant has put the product in the wrong bin. We have decided to put all small diameter fasteners in sealed packs. Whatever the pack says is what you get. We only stock 316 grade fasteners. By buying in a pack, you actually get better value Nothing, nothing is more frustrating than getting home only to find that you have 7 x cheese or pan head screws and ONE maverick countersunk becuase you failed to notice. We hope that you appreciate that we are doing this in your interest.
