company news about What Size Screws for Motherboard? Your Complete Guide

Building a PC and wondering what size screws hold your motherboard in place? You’re not alone. Using the wrong screws can damage components or cause instability. This guide covers everything you need to know about motherboard screw sizes and installation best practices.

Standard Motherboard Screw Sizes

Most modern motherboards use two critical screw types:

Why Correct Screw Size Matters

• Avoid Short Circuits: Standoffs prevent the motherboard from touching the metal case
• Secure Fit: M3 screws ensure firm attachment without damaging threads
• Compatibility: Universal sizing works with ATX, Micro-ATX, and Mini-ITX boards

Step-by-Step Installation Guide

1. Position Standoffs: Screw 6-32 standoffs into your case’s mounting holes (match your motherboard’s form factor)
2. Align Motherboard: Lower the board onto standoffs, aligning holes
3. Secure with M3 Screws: Hand-tighten screws diagonally (like a car wheel) for even pressure
4. Final Check: Ensure no standoffs touch unintended PCB areas

Common Mistakes to Avoid

• ❌ Using case screws instead of M3 screws (may strip threads)
• ❌ Overtightening (can crack PCB or warp board)
• ❌ Installing extra standoffs (can cause short circuits)

FAQ: Motherboard Screws

Q: Can I use M3.5 screws instead?
A: No – M3.5 screws are for GPU brackets. Forcing them can damage motherboard threads.

Q: What if I lost my motherboard screws?
A: Purchase "M3-0.5 PC screws" online or from hardware stores. Avoid substitutes.

Q: Do all motherboards use the same screws?
A: Yes – ATX, Micro-ATX, and Mini-ITX boards all standardize on M3 screws and 6-32 standoffs.

Key Takeaways

• ✅ Always use M3-0.5 screws to secure motherboards
• ✅ 6-32 standoffs are non-negotiable for safety
• ✅ Hand-tighten only – no power tools!

Equipped with the right screws and knowledge, you’ll build a stable, safe PC that avoids costly mistakes. Happy building!
