200 Pcs M3 x 20/25/30/35 mm Stainless Steel 304 Hex Socket Head Cap Screws Bolts Nuts Assortment Kit

This is a nice collection of longer sizes that are usually missing from the other assortments. It's good hardware as described in other reviews. So, I guess I'll review the case. The case is especially nice. It can be tossed in a tool box without worrying about the latch popping open or pieces migrating between compartments - even the little M3 hex nuts will stay put. In another, unnamed, assortment of screws and bolts I recently purchased, the top of the box is warped/bowed out so even the screws can "shaken" into another compartment. Not so with the box used in this iExcell set. Even when I've used up this hardware, I'll be re-using this case (and tossing that other one.)

The iExcell 200 Pcs M3 x 20/25/30/35 mm Stainless Steel 304 Hex Socket Head Cap is a nice set with a nice assortment.

Great screws

Using these for an upcoming project. These smoothly thread into the frame I’m using for my next drone build and look great. Highly recommend.

This set of M3 Bolts+Nuts is great for making custom 3D printed enclosures/cases for Raspberry Pi, Arduino, etc. I also use these bolts to help me join together small 3D printed mechanical/structural parts such as trusses and gearboxes.
