Review on Steel Yellow Chromate Plated Thread Across by Chris Mania

Ideal Upgrade for Port Freight 20 Ton Press - Thread Size 5/8"-11, Thickness 23/32". The Harbor Freight press came with 4 long head section bolts and nuts that would never tighten the head section of the press without movement or wobble. I replaced those 4 bolts with 8 of these nuts and 8 bolts from Revain. The best part is the $12 you can spend upgrading this high frequency press.
