Accurate sizing

Measured several pieces from the assortment and they all met standard metric specifications. Will definitely order again for future projects.

Good value but heavy box

The screws themselves are excellent quality. The only reason for 4 stars is the packaging was quite heavy to lift upon delivery. Product is great though.

Corrosion resistant

Using these in a humid environment and there is no sign of rust after three months. Very satisfied with the 304 stainless quality.

Solid hardware

Great assortment for the price. I wish the box had dividers to separate the sizes better, but the screws themselves are top notch.

Perfect for industrial use

Ordered the bulk pack for our workshop. The threading is clean and the stainless steel quality is genuine. No issues with stripping during installation.
