Precision CNC Machined Components

At California Fastener, we don’t just custom machine fasteners and components — we craft precision-engineered solutions that power industries forward. From prototype to production.

Materials We Specialize In

We work with a wide range of materials, ensuring that each part meets the exact strength, weight, and corrosion resistance required for its application. Domestic sourcing preferred – full material certifications and traceability.

Alloy Steel

Alloy steels such as B7 and B16 are designed for high-strength, high-temperature applications. B7 steel offers superior tensile strength and heat resistance for bolts, studs, and pressure vessels, while B16 steel excels in high-temperature pipelines and superheated steam systems. Our CNC machining expertise guarantees precision and durability in every component.

Stainless Steel

Stainless steel delivers exceptional strength, corrosion resistance, and heat tolerance, making it essential for medical, aerospace, and industrial applications. 304 stainless steel is widely used for structural and food-grade components, while 316 stainless steel excels in marine and chemical environments. 17-4 PH stainless steel offers high hardness and wear resistance, ideal for high-stress applications.

Aluminum

Aluminum is ideal for aerospace, automotive, and industrial applications because it is lightweight, corrosion-resistant, and machinable. 6061 aluminum balances strength and cost-effectiveness, while 7075 aluminum offers superior tensile strength for high-stress environments. Our CNC machining ensures precision and flawless finishes for prototypes and large-scale production.

Brass & Copper

Brass and copper offer excellent conductivity, corrosion resistance, and superior machinability. Brass is ideal for valves, fittings, and precision instruments, while copper is used in heat exchangers and electrical components. Our CNC machining processes ensure high precision and impeccable surface finishes.

Titanium

Titanium combines incredible strength-to-weight ratio and corrosion resistance, making it a top choice for aerospace, medical, and defense industries. Grade 2 titanium is ideal for marine and chemical applications, while Grade 5 (Ti-6Al-4V) is used in jet engines, implants, and high-performance parts. Our CNC machining ensures precision without compromising durability.

Superalloys

Inconel and other superalloys withstand extreme temperatures, pressure, and corrosion, making them essential for aerospace, power generation, and chemical processing. Inconel 625 and 718 provide superior strength and oxidation resistance, making them ideal for jet engines, turbines, and high-performance industrial parts. Our specialized machining ensures precision and durability.
