Metric Hex Cap Screws
Zinc Plated Steel Hex Head Bolts in Metric Sizes
Though these products go by many names, including hex bolts, hex head bolts and hex cap screws, the characteristic that they all share is a hexagonal head, designed to be driven by a wrench. They all are commonly referred to as both bolts and screws. Hex Cap Screws are unique because of the threading. Hex Cap Screws are partially threaded with a shoulder beneath the head. Shorter lengths are fully threaded up to the hexagonal head.
Zinc Plated Steel
Zinc adds a layer of corrosion resistance to plain alloy steel. Clear zinc has a light, shiny color and blue zinc has a bright blue hue. Zinc plated steel is not suitable for extreme environment use, as it is not as resistant to corrosion as hot dipped galvanized.
