Excellent corrosion resistance

I used these for an outdoor garden bench assembly. After several months of rain and sun, there is absolutely no sign of rust. The 304 stainless steel claim is legitimate.

Perfect fit for my woodworking projects

These screws are exactly what I needed. The flat head sits perfectly flush with the wood surface, and the anti-loosening nuts hold tight even under vibration. Great quality stainless steel.

Great for general repairs

Solid set of fasteners. The threads are clean and cut smoothly. I wish the pack came with a small storage case, but otherwise, the product quality is top-notch.

Sturdy and reliable

The cross drive grips well without stripping. I assembled a metal rack using these, and it feels incredibly solid. The anti-loosening feature gives me peace of mind.

Best seller for a reason

Fast shipping and high-quality items. These screws are much better than the cheap ones I bought locally. The combination of screw, nut, and washer makes assembly so much faster.

Good value combo pack

Very happy with this purchase. Having the washers and nuts included saved me a trip to the hardware store. The only reason for 4 stars is that the box was slightly dented on arrival, but the contents were fine.

5 FAQ

Q: Can these be used with hardwoods like oak or maple?

A: Absolutely. The sharp threading and durable steel construction allow them to penetrate hardwoods effectively without breaking. Pre-drilling is recommended for very dense woods.

Q: What sizes are included in this combination pack?

A: This specific listing contains M4 x 20mm screws. Please check the size selector dropdown if you require different dimensions like M5 or M6.

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

A: Yes, made from 304 stainless steel, they offer excellent corrosion resistance against saltwater and humidity, making them suitable for most marine applications.

Q: Do the nuts have a nylon insert for the anti-loosening feature?

A: Correct, the nuts feature a nylon ring insert which creates friction against the screw threads to prevent loosening due to vibration.

Q: Is there a warranty on the rust resistance?

A: We guarantee the material is genuine 304 stainless steel. If you experience rusting under normal conditions within a year, please contact us for a replacement or refund.
