Professional quality

I use these for repairing small appliances. The countersunk head sits perfectly flush, and the black finish matches modern appliance designs beautifully. Will buy again.

Essential for marine repairs

Used these to repair a fixture on my boat. The 304 stainless steel holds up well against salt spray, and the black coating adds a nice aesthetic touch without compromising durability.

Good value, slight color variation

Overall very happy with the purchase. The threads are clean and cut well. There is a very slight variation in the black finish between batches, but it's barely noticeable once installed.

Exactly as described

Fast shipping and the assortment box is very organized. Having multiple sizes in one kit saved me a trip to the hardware store. Highly recommended for DIY enthusiasts.

Solid hardware

Strong screws that don't bend easily. I used the M5 and M6 sizes for assembling a workbench. The only reason for 4 stars is that I wished there were more M4 screws in the pack.

Perfect fit for my project

These black screws look fantastic on my custom PC build. The hex socket is precise and didn't strip even when tightened firmly. Great quality stainless steel.

5 FAQ

Q: Can these be used outdoors without rusting?

A: Yes, 304 stainless steel offers excellent corrosion resistance for most outdoor environments. However, in highly corrosive environments like direct ocean spray, 316 grade might be preferred for long-term use.

Q: Is a VAT invoice included with the order?

A: Yes, as mentioned in the product description, a valid VAT invoice is automatically generated and included with your shipment or sent via email upon request.

Q: What size Allen key do I need for the M4 screws?

A: For M4 flat head hex socket screws, you typically need a 2.5mm Allen key (hex wrench).

Q: Are these screws magnetic?

A: 304 stainless steel is generally non-magnetic or very slightly magnetic depending on the manufacturing process. These specific black oxide coated screws show minimal magnetic attraction.

Q: Does the black coating wear off easily?

A: The black oxide finish is durable for standard applications. It may show wear over time if subjected to heavy abrasion or frequent tightening and loosening, but it provides good protection against surface rust.
