Frequently Asked Questions
Q: What thread size are these brass standoffs?
A: All standoffs, screws, and nuts in this kit use the standard M3 thread size, making them compatible with a wide range of PCB boards, Raspberry Pi, Arduino, and other common electronics hardware.
Q: What is the difference between male-female and female-female standoffs?
A: Female-female standoffs have threaded holes on both ends, allowing a screw to be inserted from each side — great for stacking boards. Male-female standoffs have a threaded post on one end and a threaded hole on the other, enabling you to screw directly into a surface on one end while accepting a screw from above on the other end.
Q: Are these standoffs compatible with Raspberry Pi and Arduino boards?
A: Yes! M3 brass standoffs are widely used with Raspberry Pi, Arduino, and most single-board computers. The assorted lengths (6mm, 10mm, 15mm, 20mm) give you the flexibility to achieve the perfect mounting height for your specific project.
Q: Do the screws and nuts included match the standoffs?
A: Absolutely. The 20 stainless steel M3 screws and 20 M3 stainless steel nuts included are sized to work directly with all the brass standoffs in this kit for a complete, hassle-free assembly.
