Great value, minor organization issues

The hardware itself is excellent quality and fits perfectly. The only reason for 4 stars is that the plastic divider in the box was slightly cracked upon arrival, but the screws were safe. Would buy again for the price.

Professional grade quality

As a contractor, I go through a lot of fasteners. This Jinchao set offers consistent threading and high-quality metal. The large flat head provides a nice clean finish on wood and metal surfaces.

Excellent corrosion resistance

Used these for an outdoor railing project. After several rainstorms, there is absolutely no sign of oxidation. The flat head design sits flush as expected. Highly recommended for exterior applications.

Perfect for our workshop needs

We ordered this set for our small manufacturing unit. The 304 stainless steel quality is evident; no rust after weeks of use in a humid environment. The variety of sizes in the box covers almost all our daily assembly tasks.

Complete set saves time

Having the nuts and washers included in the same box as the bolts is a huge time saver. No need to run to the hardware store for matching components. The cross-head grip is strong and doesn't strip easily.

Good for general procurement

Bought this for office maintenance repairs. The assortment is wide enough for most standard fixes. The steel feels sturdy and durable. Delivery was fast and packaging was secure.

5 FAQ

Q: Is the storage box durable enough for long-term use?

A: Yes, the kit comes with a sturdy compartmentalized plastic box designed for organized storage and easy transport within a workshop or job site.

Q: Does this set include both metric and imperial sizes?

A: This specific collection focuses primarily on standard metric sizes commonly used in industrial and corporate procurement. Please check the detailed size chart in the product images for exact dimensions.

Q: Are replacement parts available if I run out of a specific size?

A: We sell bulk packs of individual sizes separately. Please contact our sales team with the specific dimension you need, and we can provide a quote for additional quantities.

Q: What is the drive size for the largest bolts in the set?

A: The drive size varies by bolt diameter. Generally, larger bolts in the set utilize a PH2 or PH3 Phillips head driver. Specific details per size are listed in the technical specification sheet.

Q: Can these screws be used for marine applications?

A: While 304 Stainless Steel offers good corrosion resistance, for constant submersion in saltwater, 316 Stainless Steel is typically recommended. These are suitable for outdoor use and humid environments but not for direct, continuous saltwater immersion.
