Description

Hot dip (often misheard or mistyped as “hot deep”) nut and bolt sets are steel fasteners that have been coated with a thick layer of zinc to protect them from corrosion. They are widely used in outdoor, marine, and industrial structures because they last long in harsh weather and moist environments.���What it isHot dip galvanized nuts and bolts are standard steel fasteners that are immersed in molten zinc, forming a metallurgically bonded protective coating on all exposed surfaces.�� The term usually refers to hex bolts with matching hex nuts and washers that have all undergone the same hot dip galvanizing process.��Key propertiesThe zinc coating provides strong corrosion resistance, often giving full surface coverage and long-term protection against rust in outdoor conditions.�� These fasteners are typically made from carbon or high-tensile alloy steel (such as grade 8.8), with sizes commonly ranging from around M8 up to M72 or similar in metric series.���
