The designation 1% 4% 2014 typically reflects specific characteristics associated with the screw's design and material composition, indicating its strength and suitability for particular applications. In many cases, the numbers denote the alloying elements in the screw's material, particularly in the context of steel to enhance corrosion resistance and overall durability. For instance, 1% might refer to the percentage of a certain alloy, while 4% could represent a different additive, both contributing to the screw's ability to withstand environmental stresses.

2. Reduced Stripping Traditional screws can often strip, especially when dealing with tougher materials. Hex screws minimize this risk, as the shape of the head allows for better engagement with the tool, reducing the chances of slippage. This is a significant advantage for woodworkers aiming for precision and reliability in their projects.

4. Durability Made from materials such as stainless steel, zinc-plated steel, or other corrosion-resistant materials, expandable anchors are designed to withstand environmental factors. This durability ensures that they maintain their integrity over time, even in harsh conditions, making them a long-term solution for anchoring needs.
