Reduced Shank Hexagon Head Bolt

The head of the reduced shank hexagon head bolts is hexagonal, and there is a section with a smaller diameter in the middle of the screw. The tail of a bolt is usually flat, and some may have some chamfering treatment.

The standard specifications of the hexagon head bolt with reduced shank include thread specifications, length, performance grade, etc. There are many different specifications according to the standards. Choose according to specific needs and usage. If you are not sure how to choose the right one, you can contact us and we will provide you with professional personnel to connect with you.

Product details and parameters

Reduced shank hexagon head bolt is commonly used on automotive production lines. It is often installed on some components of the engine and parts of the bottom suspension system. It can reduce the fuel consumption of cars.

Hexagon head bolt-reduced shank is installed on aircraft and spacecraft. It can ensure that the connections between various components of the aircraft or spacecraft are stable during flight. It is also often installed on various large-scale mechanical equipment, such as machine tools, construction machinery, etc.

The shank of the hexagon head bolt with reduced shank can be easily inserted into places where larger bolts may get stuck. It is often used to modify old machinery or calibrate mismatched components. For example, outdoor equipment or ship equipment, etc.

Material Choices

Reduced shank hexagon head bolts is available in different materials to meet your various needs. For example, stainless steel, carbon steel and alloy steel, etc., are suitable for outdoor use or on ships. Please select the appropriate bolt grade according to your requirements to avoid slippage or breakage.

Product Uses

This fastener is made for situations where you need a smooth shank part to slide through pre-drilled holes easily—no getting stuck or extra friction. It’s often used in machinery assembly, especially for connecting parts that need precise alignment and occasional taking apart for maintenance. You’ll also find it in automotive manufacturing, like fixing engine components or chassis parts, because it strikes a balance between strength and easy handling. It works fine for medium-load uses, but not for super heavy-duty jobs that need full-threaded bolts. You just use a regular wrench to tighten it; no special tools are needed for putting it in or taking it out.

Product Material

Reduced Shank Hexagon Head Bolt is usually made of two main types of steel, depending on where you use it. Carbon steel is the basic pick—it’s cheap and works well for indoor, dry spots where rust isn’t a problem. If you need a bit more corrosion protection for damp rooms, we can zinc-plate it for you. Stainless steel 304 or 316 is for outdoor use, marine areas, or places with chemical exposure—these don’t rust easily and last longer. Some manufacturers also use alloy steel for higher strength needs, but that’s not common for regular use. All materials meet basic industrial standards; we don’t use rare alloys unless you have specific requirements.
