Khaled Stainless, based in Cairo, Egypt, specializes in crafting precision Stainless Steel 416 nuts designed for high-volume, machined fastener applications. Our nuts are made from certified 416 bar, featuring controlled heat treatment and threading, which ensures excellent dimensional accuracy, a superior surface finish, and complete batch traceability. Thanks to the free-machining properties of the 416 alloy, we efficiently produce hex, heavy hex, flange, and prevailing-torque styles with tight tolerances. We provide mill test certificates and optional third-party inspections, offering both standard and custom sizes, coatings, and packaging solutions tailored to meet the needs of automotive, industrial, and general engineering sectors where quick machining and dependable mechanical performance are essential.
Stainless Steel 416 is a martensitic chromium stainless alloy containing approximately 11.5–13.5% chromium, with controlled carbon levels around 0.15–0.33%, and added sulfur or selenium (about 0.15–0.35%) to enhance machinability. It also includes trace amounts of manganese and silicon, while keeping phosphorus levels low. The mechanical properties can vary based on heat treatment: tensile strength typically falls between 500 to 900 MPa, yield strength ranges from about 275 to 620 MPa, and elongation is usually between 8–25%, depending on the temper. Hardness can reach around 50 HRC when quenched and tempered, while the annealed state results in significantly lower hardness. The material comes with certification and traceability.

Khaled Stainless provides quality products with good performance by testing them for all conditions, including hardness test, spectro analysis, PMI, and flaring tests. For all the materials delivered, micro and macro examination, pitting resistance, and IGC tests are performed to ensure that the quality maintained is of the highest order. Besides our effective testing procedures, we provide comprehensive documentation, consisting of a commercial invoice, lists of packaging that include net weight and gross weight and the number of the box, and labels. Our legalized or attested Certificate of Origin combined with Third-Party Inspection Certificates testifies to our unrelenting commitment to giving better products as well as fulfilling customer satisfaction.
Stainless Steel 416 nuts are ideal for applications that demand high machinability, solid mechanical strength, and moderate corrosion resistance. Common uses include automotive fastenings, pump and valve assemblies, general engineering bolts and screws, gear and shaft collars, and turned components that require extensive machining. They perform well in indoor settings and mildly corrosive environments but are not suitable for highly corrosive or marine applications without protective coatings. Khaled Stainless is committed to providing high-quality solutions tailored to meet diverse industry needs.
