These solid brass standoffs are perfect for all you DIY-ers and electronics builders out there! Standoffs are commonly used in PC building to raise motherboards up off the frame of whatever case they're in. Standoffs can be used for DIY project building, circuit board installation and many other applications. You'll need M.3 sized screws. These standoffs ARE NOT COMPATIBLE with "American Standard" size #6-32 screws. Those are the screws commonly used to hold a PCIe card bracket onto the back of your computer case (near the I/O Interface). Again, These are made for M.3 (M3) screws, NOT #6-32 American Standard. We do sell both types as both are common for PC building. SHIPPING TO CANADA ONLY Shipping is FREE ECONOMY to anywhere in Canada.
