Great value, minor packaging issue

The screws and nuts are excellent quality and fit perfectly. One of the dividers in the plastic box was cracked upon arrival, but the hardware itself was undamaged. Would buy again.

Essential for DIY enthusiasts

I use these constantly for assembling furniture and fixing appliances. Having M3 through M10 in one box saves so much time. The spring washers are a nice touch for vibration resistance.

High quality metal

Very impressed with the finish. They look professional and the threads are cut cleanly. No stripping issues when tightening them down. Highly recommended for anyone needing a reliable set.

Good selection of sizes

The variety of sizes covers almost all my needs. The M6 and M8 bolts are particularly sturdy. I wish there were slightly more M3 screws included as I use those most often, but overall a solid purchase.

Fast delivery and great product

Arrived right on time. The case is compact and fits easily in my tool drawer. The stainless steel is genuine and magnetic testing confirms it's good grade. Very satisfied with this purchase.

Perfect assortment for my workshop

This kit has everything I need for various projects. The 304 stainless steel feels high quality and hasn't shown any signs of rust after a few months in my garage. The organizer box keeps everything neat.

5 FAQ

Q: Does the kit include a screwdriver bit?

A: No, this kit includes only the fasteners (screws, nuts, and washers) and the storage case. A Phillips head screwdriver or bit is not included.

Q: Is the plastic case stackable with other similar boxes?

A: The case features a flat lid and base designed for stable stacking, though it does not have interlocking latches specifically for connecting multiple boxes together securely.

Q: Can I buy refills for just the M4 size?

A: Currently, we only sell the complete assorted kit. We do not offer individual size refills at this time, but we often run promotions on the full set.

Q: Are these screws compatible with aluminum materials?

A: Yes, 304 stainless steel screws are generally compatible with aluminum. However, to prevent galvanic corrosion over long periods in wet environments, we recommend using an anti-seize compound or ensuring the area stays dry.

Q: What is the tensile strength rating for the M8 bolts?

A: These are standard commercial grade 304 stainless steel fasteners. While specific tensile tests vary by batch, they typically meet general ISO standards for A2-70 stainless steel, suitable for most household and light industrial applications.
