US/Imperial Products with ANSI Specification

The American National Standards Institute (ANSI) is a private non-profit organization that oversees the development of voluntary consensus standards for products, services, processes, systems, and personnel in the United States. Headquarted in Washington, D.C. the organization also coordinates and provides accreditation for U.S. standards with international standards so that American products can be used worldwide.


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 ANSI specification.

Bolts & Cap Screws by ANSI 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 ANSI 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 ANSI Specification - Pins are available in many varieties for specific jobs where additional strength is required to secure materials.

Rivets by ANSI 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.

Screws by ANSI 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 ANSI 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 ANSI Specification - Washers fit under the head of a fastener in order to increase the hold of the fastener or to increase the bearing surface.
