❓ Frequently Asked Questions
How do I know which screw size (M2, M2.5, or M3) I need for my device?
The easiest method is to remove the original screw and measure the thread diameter with a caliper. M2 screws are 2mm in diameter (approx. 5/64"), M2.5 are 2.5mm (approx. 3/32"), and M3 are 3mm (approx. 1/8"). Most smartphones and ultrabooks use M2 or M2.5, while standard desktop PC components like hard drives and optical drives typically use M3. If you're unsure, this assortment kit includes all three sizes so you can test-fit before committing.
What materials are these screws made from?
These machine screws are generally made from carbon steel with a black oxide or zinc finish, which is typical for small precision electronics fasteners. The finish provides basic corrosion resistance for indoor use. If you need stainless steel variants for a specific application, contact us to confirm availability.
Are these screws suitable for outdoor or humid environments?
These screws are designed primarily for indoor electronics and device assembly applications. They are not recommended for prolonged outdoor or high-humidity environments. For outdoor or corrosion-sensitive applications, stainless steel fasteners are generally a better choice.
What thread standard do these screws use, and are they compatible with standard metric hardware?
These are ISO metric machine screws (M2, M2.5, M3) with standard coarse metric threads. They are compatible with standard metric threaded holes, standoffs, and nuts used in PC components, laptops, and consumer electronics. They are not compatible with UNC/UNF inch-standard threads.
What drive type do these screws use, and what screwdriver do I need?
Small machine screws in this size range typically use a Phillips (cross) head drive, though some may use a flat or JIS head. A precision Phillips #0 or #00 screwdriver is generally required for M2 and M2.5 screws, while M3 screws typically use a Phillips #1. A precision screwdriver set is recommended for electronics repair work.
How are the 320 pieces organized in the kit?
The 320-piece assortment typically includes multiple lengths for each diameter (M2, M2.5, M3), organized by size. The kit is generally packaged in a compartmentalized case or sorted bags to keep sizes separated and easy to identify. Exact compartment layout may vary — contact us to confirm packaging details.
Can I use these screws to replace stripped or lost screws in my laptop or phone?
Yes, this is one of the most common uses for this type of assortment kit. Most consumer laptops and smartphones use M2 or M2.5 screws in lengths ranging from 2mm to 8mm. Having a full assortment on hand means you can find a matching replacement without ordering individual screws. Always verify thread pitch and head type before installing a replacement screw.
