Metric Products with ISO Specification
The International Federation of the National Standardizing Associations (ISA) was founded in 1926 and was heavily focused on mechanical engineering. The organization was re-organized under the current name (ISO) in 1946, and has subsequently issued over 22,000 international Standards. In the US fastener industry, ISO standards are gradually replacing their DIN equivalents and coming into more common useage.
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 ISO specification.
Bolts & Cap Screws by ISO Specification - Hex bolts and hex cap screws feature a large fastener head for distributing clamping load. These fasteners are used at high tensions and temperatures. Cap screws have a washer face underneath the head and are used in precise applications. In Europe, a cap screw refers to a bolt-type fastener that is fully threaded, whereas a bolt is the part-threaded equivalent.
Nuts by ISO 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 ISO Specification - Pins are available in many varieties for specific jobs where additional strength is required to secure materials.
Rivets by ISO 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 ISO 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 ISO 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 ISO 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.
Hand Tools by ISO Specification - Hand tools are any tools that are manipulated by hand rather than by a powered tool. Categories of hand tools include wrenches, pliers, cutters, striking tools, struck or hammered tools, measuring tools, screwdrivers, saws, and knives.
Power Transmission by ISO Specification - Power Transmission covers all of the accessories fitted in equipment that transmits power, from the power source to the receiving agent or machine. These accessories include pulleys, shafts, bearings, sprockets, drive couplings, gears, yoke ends, etc.
