Review on πŸ”© PZRT 10pcs M5 x 16mm Hammer Head Bolt T Screw and 10pcs M5 Hexagon Flange Nuts Set – Carbon Steel, Nickel Plated for 2020 Series Standard 6mm T-Slot Aluminum Profile by Ryan Nguyen

Revainrating 2 out of 5

Dimensional and parts variation with same part number/part number

II ordered 4 packs of these. The first 2 boxes worked great on my rack system. The next two boxes had the same specs but they were stamped 10t and these new boxes exactly the same PN etc do not match. Only the head is a bit big.

Pros
  • M5 flange hex nuts are made of high quality carbon steel, nickel plated finish for good corrosion resistance and better performance, high hardness and long life
Cons
  • Definitely bad product
