You cannot directly put the nuts onto the screws. You might require the help of the bolts to place them tightly onto the screws and keep them in place. Besides, you also need to look at the compatibility of these fasteners with the screws. Remember, not all the nuts to the bolts and screws. Hence, make sure you keep an eye on these factors before you try to fit in the hardware nuts onto the screws. The compatibility will not be an issue if you check out specifications before buying. Even though these nuts and bolts are small pieces, it doesn’t mean you should not spare enough time for the purchase. Remember that even a big project relies its durability on its hardware. So, keep this in mind and do not compromise with quality just to save some bucks.
