Vis à tête hexagonale 1/4-28 X 1-1/2" | Acier grade 5 zinc jaune | Filetage partiel (200 / Paquet)

I was replacing some worn bolts on a piece of equipment, and these hex head cap screws fit the thread perfectly without any binding. The yellow zinc coating looks clean and seems durable enough for shop use.

The partial threading really helped when fastening a bracket on my press—the smooth shank section kept the threads from binding in the first few turns. These Grade 5 bolts have a nice bite with a socket, and the yellow zinc finish looks clean against gray machinery. Exactly what I needed for a solid

Installing these on a milling machine jig and the partially threaded design let me get a solid clamp without bottoming out. The hex head grabs nicely with a socket wrench for proper torque. Decent finish, no burs or weak spots in the threads on the first fifty I used.
