You’ll see a few names used for tiny fasteners on this page. The label often tells you what they’re for:

• Micro screws / mini screws: A general term for very small fasteners.
• Machine micro screws: For pre-threaded holes in electronics and devices; commonly in metric sizes like M1, M1.2, M1.4, M1.7, M2, and M2.5.
• Self-tapping micro screws: Designed to cut their own threads in plastic, wood, or soft metals.
• Head styles: Pan, flat/countersunk, and washer-head are common.

When browsing, check the title or description for the size (e.g., M1.4) and head style to match your project.

A gentle approach helps with small fasteners, especially in electronics and DIY projects.

1. Match the screw type: Use machine screws for threaded holes; self-tapping for plastic or wood.
2. Pick the right size: Confirm the metric size (e.g., M1–M2.5) and length listed.
3. Use a precision bit: Choose a bit that fully fits the recess (Phillips, slotted, Torx).
4. Go slow: Turn by hand or use a low-torque driver; apply light, steady pressure.
5. Avoid overtightening: Stop when snug to reduce the chance of stripping or cracking materials.

A small precision screwdriver set can make handling and alignment easier.

Based on the assortments on this page, the smallest commonly listed size is M1 (about 1 mm nominal diameter). Many kits also include intermediate sizes like M1.2, M1.4, M1.6, M1.7, M2, and M2.5, with some sets extending up to M3 or beyond.

Exact options vary by kit, including length and head style. It’s a good idea to review each product’s size chart in the description to confirm what’s included. If you’re unsure, an assorted set with clearly labeled compartments can offer flexibility for small repairs and prototyping.

Small screws are easy to damage, so the safest approach is to use a matching precision screwdriver. Without one, removal attempts can strip the head or harm your device.

• Best option: Use a glasses/precision driver from a small tool kit available on this page.
• If you must wait: Avoid knives, coins, or oversized tools—they can slip and cause damage.
• When you try: Work under good light, apply gentle downward pressure, and keep the tool square to the screw.

If the screw is stubborn or sensitive components are involved, seeking help from a repair professional can reduce risk.

It depends on the screw type and your material.

• Self-tapping micro screws: Typically used for plastic, wood, and softer metals. A small pilot hole can help, but requirements vary by material.
• Machine micro screws: Designed for pre-threaded metal inserts, standoffs, and device housings in electronics.
• Head styles: Flat/countersunk sit flush; pan and round heads sit proud. Choose based on clearance and appearance needs.

Check each product’s description for “self-tapping” or “machine,” the metric size (e.g., M1–M2.5), and head type. If you’re unsure, an assortment kit offers multiple sizes for test fitting.
