Excellent corrosion resistance

Used these for an outdoor garden fixture. After three months of rain and sun, there is absolutely no sign of rust. Highly recommend for outdoor use.

Solid choice for DIY

Great for general household repairs. The only reason for 4 stars is that the packaging was slightly damaged upon arrival, but the screws themselves were fine.

Professional grade hardware

I run a small repair shop and these screws meet all our standards. The threading is clean and consistent across all sizes in the pack.

Perfect fit for my project

These screws are exactly what I needed for my 3D printer assembly. The 304 stainless steel feels durable and the hex heads didn't strip even under tight torque.

Good quality, great variety

The assortment kit is very convenient. Most lengths were perfect, though I wished there were a few more M3 x 12mm screws included. Overall great value.

5 FAQ

Q: Can these be used in saltwater environments?

A: While 304 Stainless Steel has good corrosion resistance, for constant submersion in saltwater, we recommend 316 Stainless Steel for superior protection against pitting.

Q: What is the tensile strength of these screws?

A: These 304 Stainless Steel screws typically have a tensile strength of approximately 500-700 MPa, suitable for most general mechanical applications.

Q: What size Allen key do I need for the M6 screws?

A: For M6 Hex Socket screws, you will typically need a 5mm Allen key (hex wrench).

Q: Are these screws magnetic?

A: 304 Stainless Steel is generally non-magnetic or weakly magnetic depending on the manufacturing process. These screws may show slight magnetism but are not strongly attracted to magnets.

Q: Does this kit include nuts and washers?

A: No, this specific listing is for the Hex Allen Screws only. Nuts and washers are sold separately in our store.
