Hex Bolt And Flat Washer Set

A hex bolt and flat washer set is a fastener assembly for holding parts together. The bolt has a hexagonal head, and the washer spreads the load under the head.

A hex bolt and flat washer set clamps two or more parts through a drilled hole. The bolt takes a nut of the same thread and class, and the washer spreads the load under the head. Monel K500 suits marine and chemical service where corrosion resistance matters.

This set is often made in Monel K500, a nickel copper alloy. It gives high strength and good resistance to seawater and many chemicals. It suits marine and chemical plant use where corrosion is a concern.

This is a general guide to checking this kind of part. It says nothing about any supplier's parts.

Ask for a mill test certificate for the bolt and washer material. On receipt, check the head marking, the washer dimensions, and that the threads are clean and undamaged.
