350PCS M3 Black Male Female Nylon Hex Spacer Standoff Screw Nut Set Assortment Kit (Black) for PCB Motherboard Circuit Board

Great standoffs of varying heights. The plastic seems that it will reliably hold circuit boards in place. I like the sizes that were included in the pack that allowed me to set circuit boards into a project at different heights so I can plugin everything needed and wire everything in a way that allows everything to remain neat and tidy. They function very well for what they are, as the back includes threaded standoffs as well as screw in standoffs with all the screws, plastic washers and nuts needed to give you the versatility to work around circuit boards where the components are close to the bolt holes. These have been durable in the installations I have used them on and the variety of sizes (standoff height and bolt size) available makes it an item that I will continue to re-buy into the future.

Got this kit to mount my Pi in an official Pi case and needed some standoff or riser spacer for future accessories. The risers are made from nylon plastic and the threads are clean and precise. The screws and nuts are made from black oxide coated steel and again everything fits perfect inside the case and the diameter is dead on at 2.5mm This kit comes with more than enough hardware all your pi needs. It comes with a variety heights and and sizes depending on your needs and for the money, it's a great kit and value. All hardware are nice and well made. Great hardware kit.

Very good Quality,and size is correct, not bad price

I primarily use the screws and standoffs in this kit for DIY projects involving Raspberry Pi's and ESP32 boards, and they work great. I don't feel like I'm going to break them with moderate torque, and even some slight bending in the longer screws doesn't feel too bad. This is a must have if you do any hobby electronics work with dev boards.

Durable nylon material, complements the brass hardware I also use when I want to insulate the boards from each other

Had the piece I needed and I got it done. Happy all the way around

Works well with Raspberry Pi and Hats. Nice variety of lengths, but not the usual Pi-centric lengths like 11mm, 16mm, etc. This are 10mm, 15mm, etc. The kit includes nuts and washers that can be used as spacers if necessary. The threads are smooth and flawless, and easy to start. The kit stinks a bit, probably made of cancer. As for durability, I wouldn't expect these would take much abuse. I wish someone made a kit like this with black metal standoffs! I only used plastic grudgingly, because I didn't really want unpainted brass.

There was a space for washers, but non-present, dont really care, but kinda strange.
