Product Description

ANSI/ASME A490M Hot Dip Galvanized Metric Heavy Hexagon Bolt with Nut


A bolt is a form of threaded fastener with an external male thread. Bolts are thus closely related to, and often confusedwith, screws. The ANSI/ASME A490M Hot Dip Galvanized Metric Heavy Hexagon Bolt with Nut is a specific type of fastener conforming to ANSI/ASME standards and designed for heavy-duty applications requiring high-strength bolts. This particular bolt, known as an A490M bolt, is crafted to metric specifications and features a hot-dip galvanized coating. The hot-dip galvanization process involves immersing the bolt and nut in molten zinc, providing superior corrosion resistance, particularly in demanding environments or outdoor settings. The heavy hexagon design of the bolt's head allows for a larger bearing surface, offering enhanced clamping force and minimizing the risk of slippage. Paired with the accompanying nut, this set is ideal for applications demanding exceptional strength and resistance to corrosion.

These A490M bolts with hot-dip galvanized finishing are commonly employed in construction, infrastructure, and structural projects where high-strength fastening is essential, and durability in challenging conditions is required. They play a vital role in ensuring secure and reliable connections in critical load-bearing applications.


The nature of the tolerance difference allows an ASME B18.2.1 hex cap screw to always fit where a hex bolt is installed but a hex bolt could be slightly too large to be used where a hex cap screw is designed in.
