iExcell 1800 Pcs M2-P0.40 x 4/5/6/8/10/12/14/16/18/20/25/30 mm Stainless Steel 304 Hex Socket Head Cap Screws Bolts Nuts Washers Assortment Kit

Good starting assortment to stock bench for device repair and 3-D printer modifications and upgrades. At least a few of just about everything.

Excellent quality screws, as described.

I ordered this assortment of M2.5 cap screws because I needed a grand total of four M2.5 x 25 mm screws, nuts and washers to mount a cooling fan on the heat sink of a small single board computer. There's not much one can say about screws, but these seem to be of very high quality and come in a compact storage case that keeps each size screw securely within its own compartment. Handling screws of this size, many of which are quite tiny, may be difficult if you have average adult-sized hands, but the cap heads of each screw are knurled on the side, allowing one's fingers to easily get them started and finger-tightened. An Allen wrench of the correct size is also supplied to tighten them securely. If you need metric hardware in this size, I highly recommend this assortment. You won't be disappointed.

Los tornillos tienen un excelente acabado, la rosca está muy bien diseñada, soy muy duros

I have purchased 5 different brands and iExcell is hands down the best set. Great range in sizes, better than any other kit.
