screw for holding nvme

[Wadim4ik22]

Hello everyone, does anyone know where I can get the screw to hold nvme? small blue screw. possibly the part number

Blue type, with M2 metric screwBlue example in placeBlack type, with M1.5 metric screw

EDIT:  The smaller size HP ones with the black plastic surround are actually 1.6 mm diameter. I looked up a purchase from McMaster.com that I used to fix a missing hold-down for a Z Turbo Drive in the past and it was "Alloy Steel Socket Head Screw, Black-Oxide, M1.6 x 0.35 mm thread, 6 mm long". It turned out to be more trouble than it was worth, and finally some of those are showing up on eBay. Corrected in the post below:

These are hard to find.  Search eBay for "hp m.2 screw" with no quotes. Both the HP blue and black ones were in there today.    Standard M.2 stick hold-down screws generally are M2-threaded wide head short metric screws. These HP ones are different, highly engineered, and nice until you lose them.

There are two HP types... some have blue plastic and some have black plastic as part of their build. Either type is meant to firmly slip onto the "rear" half-round notch of a M.2 stick, but their center screws are of two different sizes. Central in the plastic is a finely machined brass nut with a specially milled steel screw running through that. The notch in the plastic keeps the M.2 stick properly elevated above the motherboard. This is almost nanotechnology...     In some of the HP/Compaq PCs they just use plain old inexpensive M2-threaded metric screws. The more advanced ones are not cheap for HP to make, but they are easy to lose. See install tip below.

Either type screw is tiny and relatively soft. Don't crank down on the screw because it can be easy to strip... just gentle snug. The plastic part has a notch with side ears that you slip evenly onto the M.2 stick. This is meant to be done while both are out of the case and do it over a towel. The notch should be a snug fit onto the M.2's circuit board so it won't easily fall off. Then you insert the contacts end of the stick into the M.2 socket fully, fold it down to the motherboard's threaded insert, and screw on carefully. Once you know you can eyeball the motherboard's insert for whether it is a M1.5 vs M2 size (which you can see in the pics above).

Blue = M2 metric threads and black = M1.6 slightly thinner metric threads. The black ones are used also on the HP Z Turbo Drives, both G1 and G2. The blue ones don't fit on those. I have no part numbers for you.

most nvme screws are the common m2x3 mm screw size available on amazon/Newegg

however some HP products use a non std size of m1.6x6mm and you may still need a washer for the screw
