Fastener Solutions socket products are primarily used for high-strength fastening applications. These internally wrenched, high-strength fasteners are made from durable materials that allow them to last for years to come. With a minimum tensile strength of 170,000 psi, and a minimum Rockwell hardness of C37, these screws are stronger than Grade 8 screws. We keep an extensive inventory of sockets from socket head cap screws to socket pipe plugs.
The socket product sizes we offer come in inch (thread fit class 3A and meets standards ASTM A574) and metric (thread fit class 5g6g and meets standards DIN912/ ISO4762); the length is measured from under the head. Plating and coatings are typically black oxide or zinc, although custom plating or coating is available upon request. View our product inventory below.
