Excellent corrosion resistance

Used these for an outdoor garden box assembly. After a few weeks of rain, there is no sign of rust. Highly recommended.

Solid hardware

Bought the M4 size for a computer build. They are strong and the finish looks professional. One star off only because packaging was a bit loose.

Good quality, fast shipping

Great value for the price. The cross drive is well-formed and didn't strip during installation. Would buy again.

Precise threading

The machine threads are cut very precisely. They screw in smoothly without any binding. Great for fine mechanical work.

Perfect fit for my project

These screws are exactly what I needed for my electronics enclosure. The 304 stainless steel feels durable and the heads sit perfectly flush.

5 FAQ

Q: Is the thread full length or partial?

A: These are machine thread screws with full threading along the shank, designed to be used with nuts or tapped holes.

Q: What driver size do I need for the M4 screw?

A: For the M4 Cross Countersunk screws, we recommend using a PH2 (Phillips #2) screwdriver bit for optimal torque and to prevent stripping.

Q: Do you offer an M10 size in this style?

A: Currently, this specific listing covers sizes M2 through M8. Please contact us directly if you require M10, and we can check our bulk inventory for you.

Q: Are these screws magnetic?

A: 304 Stainless Steel is generally non-magnetic or slightly magnetic depending on the manufacturing process, but they are not strongly attracted to magnets like carbon steel.

Q: Can I get a VAT invoice for this order?

A: Yes, as stated in the description, VAT invoices are available. Please provide your company tax details in the order notes or contact support after purchase.
