US/Imperial Products with ASME Specification

The American Society of Mechanical Engineers (ASME) is a private non-profit organization that oversees the development of voluntary consensus standards for products, services, processes, systems, and personnel around the world. Founded in 1880 and Headquarted in Washington, D.C., the organization is known for developing and maintaining over 600 widely-used engineering standards and codes, particularly in mechanical enginnering The ASME also coordinates and provides accreditation for U.S. standards with international standards so that American products can be used worldwide.
The ASME standards are sometimes referred to as the ASME/ANSI standards. In this case the ANSI refers to the American National Standards Institite, which is broadly tasked with overseeing and coordinating various standards within the United States and ensuring their compatibility with overseas standards organizations.


At The FCH Sourcing Network you will find hundreds of thousands of fasteners within our database of surplus, odd lot, slow-moving and hard to find fasteners that conform to the ASME specification.

Bolts & Cap Screws by ASME Specification - Hex bolts and hex cap screws feature a large fastener head for distributing clamping load. Heavy hex bolts feature a larger head. These fasteners are used at high tensions and temperatures. Cap screws have a washer face underneath the head and are used in precise applications. Heavy hex bolts and Structural Bolts are commonly used to make structural connections in buildings, bridges, and railways.

Nuts by ASME Specification - Nuts, or mating fasteners, are available in hundreds of different shapes and sizes for any project or application. Varieties are normally hexagonal or square in shape, and have either coarse or fine internal threads that correspond to those of a mating bolt or screw.

Pins by ASME Specification - Pins are available in many varieties for specific jobs where additional strength is required to secure materials.

Rivets by ASME Specification - Rivets are fasteners used to permanently hold two pieces of material, usually metal, together. In general, riveting involves placing the shank of the rivet through a specific-sized hole in two or more materials, and then tightening by deforming the tail end of the rivet.

Screws by ASME Specification - Screws are one of the most versatile, useful types of fasteners, and are available in multiple sizes and styles. In different countries, and in different industries, there is some confusion in the distinction between screws and bolts. Some definitions of screws include the requirement that they be fully threaded, and these may also often be called Bolts.

Studs & Threaded Rod by ASME Specification - Studs and threaded rods are fasteners that are designed primarily to be used in tension. They differ from bolts and screws in that they do not have heads (but can be used for similar purposes), and they differ from each other mainly by their length. They can be fully threaded, or just have threads at each end.

Washers by ASME Specification - Washers are usually manufactured from thin plate (disk-shaped or square) with a hole to fit under the head of a fastener in order to distribute the load and increase the hold of the fastener by increasing the bearing surface.
