Hazlewood Fasteners’ 17-4 PH nuts ensure assemblies remain secure and stable over time, providing engineers and designers with confidence in harsh industrial, marine, and aerospace environments where both durability and precision are paramount.
17-4 PH nuts are composed of a stainless steel alloy containing roughly 17% chromium, 4% nickel, and small amounts of copper and niobium. This composition allows for precipitation hardening, which imparts high tensile strength, excellent fatigue resistance, and outstanding hardness. The nuts maintain dimensional stability and resist corrosion in a variety of aggressive environments, including chemical, marine, and high-temperature settings. With superior mechanical properties, 17-4 PH nuts provide secure, long-lasting fastening, ensuring structural integrity and reliability in applications where strength and durability are essential.
