We at California Screw Products manufacture an array of stainless steel screws and bolts designed to meet the extreme environments typical of the aerospace industry.
California Screw Products (CalScrew) is a part of the Avantus Group, a collection of organizations that specialize in the production of C-class components and assemblies, and supply chain logistics, based in the United States and the United Kingdom. Singularly, we each possess industry-leading skills and capabilities, and as a family group we offer unrivalled procurement, product management and production capabilities to aerospace and defense clients across the globe.

High quality production services
There is no space for compromise in the aviation industry. Even the smallest, most seemingly insignificant part has a vital role to play, and its failure could have potentially devastating consequences. At CalScrew we apply the same level of detail and uncompromising quality to every product we manufacture, from the simplest stainless steel screw to more complex fasteners.

A broad portfolio
Our fastener production capabilities include a broad range of alloy steel and stainless steel screws and bolts, each of which can be tailored to meet our clients’ specific needs in terms of size, strength and torque. Our skilled engineers and technicians possess the experience and have access to the technology to enable them to guide customers to the right design, production and finishing processes to meet their needs, while maintaining compliance with industry guidelines.

Quality assured
With AS9100 and ISO9001 certification, we at CalScrew operate in compliance with DFARS (10 USC 2533b(h)(3)), which ensures that more than half of our specialty metals are derived from domestically melted metals. Our fully in-house quality assurance processes enable us to ensure the quality of materials and parts at every stage of the production process, saving time and ensuring that every product that leaves our state-of-the-art facilities meets our high standards.
