The shipping cost for Classic Square Head Bolt is not high because they are small in size and light in weight. A box of 100 small bolts usually weighs less than one pound, so the shipping cost to overseas destinations is approximately between 6 and 12 US dollars. Shipping within the United States or Europe is cheaper - usually the regular shipping cost is less than 4 US dollars. If your order amount exceeds 300 US dollars, we will cover the standard shipping cost - no additional charges will be required. We have reached cooperation with logistics companies and can strive for more favorable cooperation prices to effectively reduce your transportation costs. Therefore, whether you are purchasing a few bolts for an emergency repair or a full tray of bolts for your workshop, the shipping cost will not have a significant impact on your total cost.
