Absolutely horrible quality. Screws are so soft that they can’t be unscrewed without seriously damaging them.

Worked perfectly for my OneWheel GT fender. I 3d printed a fender and needed longer screws. This did the job.

Our son is a full time wheelchair user and we have had issue after issue with screws needing replaced and the company we use to fix it taking months. We bought these to make little fixes ourselves and they are perfect! Great price for the assortment and number you get. Highly recommend

all sizes packaged in labeled bags. There is a protective oil on all the screws that should be removed before use. I used 99% isopropyl alcohol. all screws appear to be quality made.

All of the sizes except for the M3x12 were correct, the M3x12 were actually M4x12, And unfortunately the M3x12 were the ones I bought the set for. Every screw in the M3x12 bag is an M4.

Looks like a quality product. However, the screws came in individual zip lock bags. Not that big of a deal, but if you were looking for a plastic tray holder, keep looking.

Each different length of screw were in a separate plastic bag. I was looking for screws in a particular length which were part of the kit. So far, they’ve been very useful. Plating seems durable also
