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.

Nuts, on the other hand, serve as the complementary part to bolts. When tightened onto a bolt, they provide the necessary clamping force to hold components together, ensuring stability and resistance against dynamic forces such as wind, earthquakes, or the weight of the structure itself. The choice of nut, whether it's a hex nut, wing nut, or castle nut, is determined by factors like accessibility, safety considerations, and the need for locking mechanisms.
