Excellent quality stainless steel

These eye bolts are solid and well-made. The 304 stainless steel finish is smooth and shows no signs of rust after a month of outdoor use. The assortment kit had exactly the sizes I needed for my garage organization project.

No rust after rain exposure

Installed these on an exterior fence gate six months ago. Despite heavy rain and humidity, there is zero corrosion. True 304 stainless steel as advertised. Very satisfied with the durability.

Sturdy and reliable

I am a contractor and go through a lot of hardware. This kit is consistent in quality. The welds on the eye bolts are clean and strong. Highly recommend for professional or DIY use.

Good value, missing one size

Overall a great kit for the price. The washers fit perfectly and the nuts thread smoothly. I noticed one specific size was short by two pieces in my box, but customer service resolved it quickly. Would buy again.

Great assortment

The variety of sizes in this kit is very useful. It saves me from having to buy individual packs. The only reason for 4 stars is that the plastic case lid is a bit flimsy, but the hardware itself is top-notch.

Perfect for hanging plants

Used these to hang heavy planters on my patio wall. They hold securely and look very professional. The spring washers ensure the nuts don't loosen over time due to wind movement.

5 FAQ

Q: Does the kit include a drill bit?

A: No, this kit contains only the eye bolts, nuts, flat washers, and spring washers. You will need to purchase appropriate masonry drill bits separately based on your wall type.

Q: What is the maximum weight capacity for the M8 size?

A: The safe working load varies by installation angle and wall material. For vertical loads in concrete, the M8 bolt typically supports up to 150kg, but please consult a structural engineer for critical applications.

Q: Can I use these on drywall without anchors?

A: No, eye bolts should not be installed directly into drywall without proper hollow-wall anchors or hitting a stud. Drywall alone cannot support the shear strength of these bolts.

Q: Is the thread metric or imperial?

A: This assortment kit features standard Metric threads (M4, M5, M6, M8, etc.). Please check the product specification table for the exact pitch details before purchasing.

Q: Are these suitable for saltwater environments?

A: While 304 stainless steel offers good corrosion resistance, we recommend 316 grade for direct, continuous saltwater immersion. For coastal air exposure, these work well.
