Which Screws for Motherboard: Complete Guide for PC Builders

Which screws for motherboard is one of the most common questions asked by new PC builders. When you open a computer case and look at the shiny motherboard, you may wonder: How do I secure this safely? The answer lies in using the right screws. Choosing the correct screws is important because they keep your motherboard stable, prevent damage, and ensure smooth performance.

In this guide, we will explore everything about motherboard screws. We will cover screw types, sizes, materials, installation tips, mistakes to avoid, and even FAQs. By the end, you will know exactly which screws for motherboard are right for your build.

Why Knowing Which Screws for Motherboard Matters

• 🛠️ Prevents damage: Using the wrong screws can crack or bend the board.
• 🔒 Ensures stability: Correct screws keep the motherboard firmly in place.
• ⚡ Improves safety: Proper screws avoid short circuits caused by loose metal.
• 💻 Helps airflow: A stable motherboard allows better cable management and cooling.

Because of these reasons, every PC builder should learn which screws for motherboard before starting a build.

Types of Screws Used for Motherboards

1. Standard ATX Motherboard Screws

Most ATX motherboards use 6-32 UNC screws. These are coarse-thread screws that fit into the standoffs inside your case. They are about 1/4 inch long and are the most common type.

2. M3 Screws

Smaller motherboards, such as micro‑ATX or mini‑ITX, often use M3 screws. These are metric screws with a finer thread. They are slightly thinner than 6-32 screws but still strong enough to hold the board.

3. Standoff Screws

Standoffs are small brass or steel spacers that lift the motherboard off the case. They prevent direct contact between the board and the metal case. Standoff screws are used to secure the motherboard to these spacers.

4. Specialty Screws

In some cases, especially from brands like Dell, HP, or Lenovo, may use proprietary screws. These are less common but worth mentioning. Always check your case manual to confirm which screws for motherboard are required.

Which Screws for Motherboard: Size and Length

• 6-32 UNC screws: 3–5 mm in length, coarse thread.
• M3 screws: 4–5 mm in length, fine thread.
• Standoff screws: Usually 6 mm tall brass spacers with threaded holes.

The length matters because too long screws can damage the board, while too short screws may not hold it securely.

Materials Used in Motherboard Screws

• Steel screws: Strong and durable, most common.
• Brass standoffs: Non‑corrosive and safe for electronics.
• Nickel‑plated screws: Resist rust and look shiny.

When asking which screws for motherboard, remember that material quality is just as important as size.

How to Install Motherboard Screws Correctly

Step 1: Prepare the Case

Place standoffs in the correct holes that match your motherboard size (ATX, micro‑ATX, mini‑ITX).

Step 2: Align the Motherboard

Carefully lower the motherboard into the case, aligning it with the standoffs.

Step 3: Insert Screws

Use a screwdriver to insert screws gently. Do not overtighten, as this can crack the board.

Step 4: Check Stability

Once all screws are in place, lightly shake the case. The motherboard should not move.

Mistakes to Avoid When Choosing Which Screws for Motherboard

• ❌ Using random screws from other devices.
• ❌ Overtightening screws.
• ❌ Forgetting standoffs.
• ❌ Mixing screw types (M3 vs 6-32).
• ❌ Leaving screws loose.

Which Screws for Motherboard in Different Case Types

ATX Cases

Usually require 6-32 UNC screws with brass standoffs.

Micro‑ATX Cases

Often use M3 screws with smaller standoffs.

Mini‑ITX Cases

Compact builds may use M3 screws exclusively.

Pre‑built PCs

Brands like Dell or HP may use custom screws. Always check the manual.

Which Screws for Motherboard: Brand Examples

• Corsair cases: Typically include 6-32 screws and standoffs.
• NZXT cases: Provide both M3 and 6-32 screws.

Using these terms naturally helps search engines understand the topic better.

Advanced Notes for Enthusiasts

Some high‑end cases use tool‑less designs, meaning you don’t need screws at all. However, most traditional builds still rely on screws. Enthusiasts often prefer steel screws with nickel plating for durability.

Conclusion

Choosing which screws for motherboard may seem like a small detail, but it is a critical step in building a computer. The right screws ensure stability, safety, and performance.

Most ATX boards use 6-32 UNC screws, while smaller boards often use M3 screws. Standoffs are equally important because they prevent short circuits. By following the tips in this guide, you can build your PC with confidence and avoid costly mistakes.
