Missing a few M4 sizes

The quality is fine, but my kit seemed to be missing a couple of the M4 lengths listed on the box. Contacted support and they resolved it quickly though.

Good quality, slightly soft metal

Overall very happy with the purchase. They look great and haven't rusted yet. Just be careful not to overtighten the smaller M2 sizes as they can strip easily.

Clean finish and precise threads

Used these for assembling a custom PC case mod. The threads are cut very cleanly and they screw in smoothly without cross-threading.

Great for outdoor furniture repair

Replaced some rusted bolts on my garden bench with these. Since they are 304 stainless, I expect them to last much longer. Very satisfied.

Perfect fit for my electronics project

These screws are exactly what I needed. The 304 stainless steel feels durable and the heads sit perfectly flush. Great variety of sizes in the kit.

Excellent value for money

You get a huge amount of screws for the price. The storage box is a nice bonus to keep everything organized. Will definitely buy again.

5 FAQ

Q: Are these screws suitable for use in marine environments?

A: While 304 stainless steel offers good corrosion resistance, for constant exposure to saltwater, we recommend 316 grade stainless steel for maximum longevity.

Q: What is the thread pitch for the M5 screws?

A: The M5 screws in this set feature a standard coarse thread pitch of 0.8mm, which is the industry standard for general purpose machine screws.

Q: Is the storage box durable enough for long-term storage?

A: The included box is made of sturdy plastic with dividers, designed specifically for organizing and storing these small hardware components safely.

Q: Can I use a standard Phillips head screwdriver with these?

A: Yes, these screws have a standard cross recess (Phillips) drive. We recommend using a #1 driver for M2-M3 and a #2 driver for M4 and larger sizes.

Q: Does this kit include nuts or just the screws?

A: This specific kit includes only the flat head machine screws. Nuts are not included as these are designed to be threaded directly into tapped holes.
