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.
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.
Delrin
Delrin offers exceptional dimensional stability, low friction, and excellent wear resistance, making it ideal for precision mechanical components. Its superior machinability allows for tight tolerances in gears, bushings, bearings, and valve components. Our CNC machining delivers smooth finishes and consistent quality for both prototypes and production runs.
PEEK
PEEK delivers outstanding performance in extreme temperatures, harsh chemicals, and high-stress environments. Its strength, biocompatibility, and thermal stability make it essential for aerospace, medical, and semiconductor applications. Our CNC machining ensures precision and reliability for demanding components where failure is not an option.
ABS
ABS combines strength, impact resistance, and affordability, making it a versatile choice for prototypes, enclosures, and functional components. Its excellent machinability and smooth surface finish make it ideal for consumer products, automotive parts, and electronic housings. Our CNC machining processes ensure consistent results for both short runs and large-scale production.
