Products Description

Flat head hexagonal bolt material has carbon steel and other options, carbon steel material, high strength, relatively low cost, can meet the general industrial use. Stainless steel material has excellent corrosion resistance, commonly used in the environment of high requirements for rust, such as food processing equipment, outdoor facilities.

In terms of dimensions, they are available in metric and imperial series, and can be precisely adapted to various types of nuts and parts with internal threads. The principle of its function is to withstand certain tensile and shear forces through the threads of the close bite, for many mechanical structures, building decoration, electronic equipment and other fields to provide a strong guarantee of reliable connection.

Key Features

Hex head design

Standard side-to-side dimensions ensure compatibility with standard wrenches and sockets, enabling convenient tightening and efficient torque transfer.

Flat-top design

The head's bearing surface is flat, ensuring a tight fit with washers and connected components for even force distribution; it also facilitates operation with low-profile wrenches in confined spaces.

Full-threaded or partial-threaded

Available in full-threaded (for higher nut positions) or partial-threaded (for positioning and shear resistance requirements) configurations as needed.
