M20-2.5 X 90mm Zeskantbout | Klasse 8.8 Staal Geelzink | Volledig schroefdraad (25 st./verpakking)

The hex head on these cap screws grabs a socket perfectly, making installation on my press jig much smoother than with standard bolts. The yellow zinc coating looks consistent across all 25 pieces I received.

Used them to bolt a guard frame onto an old press at work, and the Class 8.8 steel took the torque without a hint of stripping. The yellow zinc finish hasn't shown a single speck of rust after a week of oily shop air, which is more than I can say for the last batch I tried.

The threads are perfectly clean and uniform across all 25 pieces, and the 90mm length with full threading made alignment in my jig a breeze; the hex heads seated firmly in my socket without any stripping issues. For the price per unit, these are solid hardware for general machine assembly.
