Good value, minor packaging issue

The screws and nuts are great quality and fit perfectly. One of the dividers in the plastic box arrived cracked, but the hardware itself was undamaged. Would buy again just for the fasteners.

Excellent assortment for general repairs

This kit has everything I needed for my home workshop. The stainless steel quality is top-notch, and the organizer box keeps all the sizes neatly separated. Highly recommended for anyone doing mixed metric projects.

Rust resistant and durable

Used these for an outdoor garden project. After three months of exposure to rain, there is absolutely no sign of rust. The 304 grade steel really makes a difference.

Perfect for electronics enclosures

I use these M3 and M4 sizes frequently for mounting circuit boards. The countersunk heads sit flush exactly as they should. No stripping issues with the Phillips drive either.

Solid set, wish it had more M6

Great variety pack. My only critique is that the count for M6 bolts is a bit low compared to the smaller sizes if you are working on heavier machinery. Otherwise, excellent product.

Must-have for DIY enthusiasts

Having washers, nuts, and screws all in one matching set saves so much time. The threads are clean and precise. This is now a staple in my toolbox.

5 FAQ

Q: What tool do I need to install these?

A: Since these feature a cross recessed head, you will need a standard Phillips head screwdriver or a Phillips bit for your power drill.

Q: Are these screws compatible with aluminum profiles?

A: Yes, these 304 stainless steel screws are commonly used with aluminum T-slot profiles and frames without causing galvanic corrosion in standard environments.

Q: Does this set include hex keys?

A: No, this set includes only cross recessed (Phillips) screws, lock nuts, and washers. Hex keys are not required for installation nor included in the package.

Q: Can these be used in marine environments?

A: While 304 stainless steel offers good corrosion resistance, for direct saltwater immersion or harsh marine coastal areas, we recommend 316 grade stainless steel for maximum longevity.

Q: Is the storage box stackable?

A: The included organizer box has a flat lid but does not feature interlocking stacking latches. It is designed primarily for compartmentalized storage within a drawer or shelf.
