Ella F. ★★★★★

I needed some heavy-duty fasteners for a frame jig, and these hex head cap screws were exactly what I was looking for. The class 8.8 steel feels reassuringly strong, and the 30mm length worked perfectly through thick brackets.

Hazel B. ★★★★★

The yellow zinc coating on these is holding up well even with a bit of rain exposure on my trailer hitch—solid grip with a socket too. Needed a full thread for a tight fit and these delivered without any fuss.

Eva ★★★★★

These M20 hex bolts were exactly what I needed for a heavy-duty machinery repair, and the 8.8 grade steel feels solid. The yellow zinc coating is a nice touch, giving them a clean, rust-resistant finish that matches perfectly.
