450Pcs M3/M4/M5/M6/M8 Allen Head Socket Hex Grub Screw Set Assortment Kit with Internal Hex Drive - 12.9 Class Black Alloy Steel

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.

The parts are nicely separated by type and size. Included in the box is a map of that. It is loose so we taped it in so we can always see the layout. Very happy.

Good quality and useful assortment for fixing today’s imported products. Fixed a loose towel bar and improved a speaker wall bracket, for example. Much better price than paying $2 each at the so-called “hardware” stores.

Headline says it all. The screws work great and have no issues, but the case they come in is incredibly shoddy. It buckles when you open it so all four sides bulge outwards. As a consequence, the compartment dividers do not stay in their slots, so prepare for all your different set screws to mix together in the case. Not ideal.

Good value, comes in handy for what I need.

I bought this kit for one screw for an oil passage plug for a Stihl Chainsaw that was obsolete.

The grub screws in this set are very well made, but the container that they are put in is about as cheap as you can get. The grub screws were all over the place and I had to get another, better made, container.
