Perfect for outdoor projects

Used these for a garden bench assembly. Since they are 304 stainless, I don't have to worry about rust when it rains. The extended cylinder head looks very clean too.

Solid hardware

The threads are clean and the nuts fit snugly. One screw had a slight burr on the head, but it didn't affect functionality. Would recommend for general use.

Good variety pack

Very happy with this purchase. The case keeps everything organized. I only wish there were slightly more washers included relative to the number of bolts, but overall a great value.

Great organization box

Beyond just the quality of the steel, the plastic case is fantastic. Each size has its own compartment. No more digging through a junk drawer for the right bolt!

Excellent quality for the price

These screws are solid. The 304 stainless steel feels premium and the hex sockets are perfectly machined without any stripping issues. Great assortment for my workshop.

5 FAQ

Q: Does this set include an Allen key for installation?

A: No, this set includes the screws, nuts, and washers only. You will need to provide your own metric hex key set.

Q: What is the range of sizes included in this box?

A: This collection typically ranges from M3 to M10 in various lengths. Please refer to the detailed size chart in the product images for the exact count per size.

Q: Can these be used with aluminum frames without galvanic corrosion?

A: Stainless steel can cause galvanic corrosion when in direct contact with aluminum in the presence of an electrolyte. We recommend using a barrier paste or ensuring the environment remains dry.

Q: Is the plastic case sturdy enough for job site transport?

A: Yes, the case is made from high-impact ABS plastic with secure latches, designed to withstand typical job site conditions and keep your hardware organized.

Q: Are these screws suitable for marine environments?

A: While 304 stainless steel offers excellent corrosion resistance for most outdoor applications, 316 stainless steel is generally recommended for direct saltwater or harsh marine environments.
