The aim of the article is that introduce bolt fasteners development status at home and abroad, the stainless steel hex bolt dimensions, the stainless steel hex bolt weight, the standard specification for stainless steel bolts, the hex cap screws and studs, the different types of hex bolts, the hex bolt full thread dimensions, the hex bolt head design, hex bolt head dimensions.


Hex bolts, also called hexagon screw head bolts, hex cap bolts, hex-cap screws, or machine bolts, are a very common choice when it comes to construction and repair. Hexagon screw head bolts come in a large variety of sizes and diameters.


Hexagon bolts in Stainless Steel. With the addition of alloying elements to low Carbon steel such as Chromium and Nickel in high amounts, Carbon steel develops a resistance to corrosion or staining, and will not lose this resistance if scratched; it is then known as Stainless steel. With over 11% chromium, Stainless steel is about 200 times more resistant to corrosion than mild steel the alloying elements are a lot more expensive than normal carbon steel. In common fastener stainless steel grades, nickel can account for up 20% by weight but this can represent more than half of the value. Nickel prices fluctuate and this there could be a cost penalty for using stainless steel fasteners.

Each different hex bolt material has particular properties to fit specific applications. Hexagon screw head bolts are made from a variety of materials to accommodate the wide range of applications in which hex cap bolts are used.

Stainless steel bolts: Common choice of hex screws since they don’t need any coating and are corrosion resistant.

Carbon steel bolts: The most common hexagon screw head bolts are zinc plated for added corrosion resistance.

Alloy steel bolts: These types of hex bolts are made to withstand an enormous amount of pounds per square inch. They are coated with either cadmium or zinc plating to protect them against corrosion.


Hex bolts are available with standard threading or full threading, depending on the length of the bolt. Applications for hexagon screw head bolts can vary from exterior and automotive to marine, coastal, and high temperature environments.
