Head Design: Like standard hex head bolts, hex flange head bolts have a hexagonal head designed to be tightened or loosened with a wrench or socket tool. However, they also feature an integrated flange beneath the head.
Flange Design: The flange of a hex flange head bolt is a flat, washer-like feature that extends radially outward from the base of the bolt head. This flange provides a larger load-bearing surface and distributes clamping force more evenly over a wider area, reducing the risk of damage to the mating surface and improving resistance to loosening due to vibration.
Threaded Shaft: Hex flange head bolts have a partially or fully threaded shaft extending from the head to the end of the bolt, allowing them to be threaded into a tapped hole or used with a nut.
Materials: Hex flange head bolts are typically made from steel, stainless steel, or other materials depending on the application requirements. They may be zinc-plated, galvanized, or coated for corrosion resistance, particularly in outdoor or harsh environments.
Sizes: Hex flange head bolts are available in various sizes, including different diameters, lengths, and thread pitches, to accommodate different applications. They are commonly designated by their diameter, length, and thread pitch (e.g., 1/4"-20 x 2" hex flange head bolt).
Applications: Hex flange head bolts are used in a wide range of applications, including automotive, machinery, construction, and industrial equipment. They are commonly used to fasten components together or to secure objects to metal or other surfaces where resistance to loosening and improved load distribution are desired.
