Overview

Adfast Component LTD: Nonferrous Socket Set Screws for Marine and Industrial Applications

Adfast Component LTD proudly offers high-quality nonferrous socket set screws in sizes ranging from 0.125″ (#5) to 2.000″, square head set screws from 0.190″ (#10) to 1.500″, and slotted headless set screws from 0.125″ (#5) to 0.750″. Manufactured to meet ASTM F3042 specifications, these screws are crafted from durable nonferrous alloys ideal for marine environments and U.S. Navy applications. Designed to withstand seawater exposure and salt-laden atmospheres, they deliver reliability in harsh conditions while remaining versatile for other industrial uses.

Please note, copper-based alloys are not recommended for applications requiring high hardness to lock components, such as shafts, due to their mechanical limitations. Availability of certain alloys or sizes may vary. For specific requirements or assistance, we encourage you to contact Adfast Component LTD for tailored solutions to your application needs.

Bolting Components Marking

Product Shall be Marked with our manufacturing trade mark Adfast Component LTD along with the designated Grade.
Grade and manufacturer’s identification symbols shall be applied to one end of studs and to the heads of bolts and screws of all sizes. (If the available area is inadequate, the grade symbol may be marked on one end and the manufacturer’s identification symbol marked on the other end.) For bolts and screws smaller than 1⁄4 in. [6 mm] in diameter and studs smaller than 3⁄8 in. [10 mm] in diameter and for 1⁄4 in. [6 mm] in diameter studs requiring more than a total of three symbols, the marking shall be a matter of agreement between the purchaser and the manufacturer.
