Excellent product and a fast delivery

These bolts do exactly what they say and they came to the exact specs I ordered them to. I ordered something which was designed to be mounted to a 1-2mm thick aluminium frame and arrived with bolts 20mm long, including a washer & nut. I needed to mount mine to wood with a thickness of 20mm, so needed bolts around 18mm longer ... Thus, I ordered these. I ordered M6 x 40mm and these fit the 6mm diameter holes perfectly. The nuts which arrived with the default bolts fit these bolts perfectly, so the threading was exactly as it should be. Ulitmately, if you order M6 x 40mm bolts here, you get M6 x 40mm bolts. That's a 5/5 if you ask me.

The item it was to big fir the intended purpose but the actual item was alright and properly build

I bought these allen bolts to fit a rear luggage carrier on a motorcycle. They were exactly what I needed and a perfect fit. Being stainless steel they will not rust. Very good value and seem to be very good quality.

I don’t understand what these strange things are , what are they for ?

As described

Very very fast delivery and good quality product.
