We carefully packaged the Authentic Square Head Bolt to prevent them from getting damaged during transportation. We classified them according to size to ensure that the larger bolts would not crush the smaller ones. Each head bolt was wrapped with a small piece of foam to protect its edges from damage. The boxes were marked with "Fragile" to inform the delivery personnel to handle them with care. We also did not fill the boxes too full - so as not to put too much pressure on the bolts. Thanks to these measures, almost no bolts were damaged - in fact, the damage rate was less than 1%. But if any bolt was bent or damaged upon delivery, just let us know and we will provide a replacement free of charge - no additional charge will be required.
From the very beginning, we ensured that our Authentic Square Head Bolt were made of high-quality materials. The steel would undergo tests to ensure it was strong enough to remain intact under pressure - so that no inferior metals would appear in your order. When choosing stainless steel, we usually choose mainstream grades such as 304 or 316. The key reason is that it has excellent anti-rust ability and can effectively prevent the erosion of corrosive factors in the environment. Each batch of materials would be inspected for any defects such as cracks or impurities. Any item failing to meet our standards will not be utilized. Thus, each square head bolt starts from high-quality materials - which is very important for its performance.
