Review: Quality parts - Good quality parts and had exactly what I needed and was shipped fast. Thanks!
Review: Worth the price easily - While this probably has sizes you may never need, it has almost all that you will need. The big box home improvement places charge 1-2$ for a package of 4, if they even have the size you need, as more and more they stop carrying these types of items because they need the equation to be dollars of profit per square foot over actually being of service. And then online you have to buy 50 of the item that you need 2 of. But I digress. This comes in at less than 3 cents per piece and is filled with sizes that you aren't easily finding down the street but when you need them you need them. The case is "meh" but functional and could be worse. It's paid for itself already in the few I've used and not going to search, and I will need more for future projects.
