Products with ISO Specification
Bolts & Cap Screws - 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.
Keys - Keys are shaped pieces of metal, pins, bolts, or wedges inserted into a hole or between parts so as to lock the parts together and stop them from movimg relative to each other.
Nuts - 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 - Pins are available in many varieties for specific jobs where additional strength is required to secure materials.
Screws - 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 - 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 - Washers fit under the head of a fastener in order to increase the hold of the fastener or to increase the bearing surface.
