Bolts
When it comes to aerospace and defense engineering, every part, regardless of its size or cost, plays a vital role. Fasteners, such as bolts and screws, are essential; failure to perform as required could lead to catastrophic consequences. At CalScrew, we are experienced in designing and producing specialty engineering bolts that are designed to withstand the extreme conditions associated with aviation and defense, such as extreme temperatures, high levels of vibration, and exposure to UV rays or chemicals.

Quality assured
We understand that any compromise on quality can result in stoppages on your production lines and potentially lead to safety issues.  All of the defense and aircraft bolts manufactured in our state-of-the-art facilities are made of the highest quality stainless steel or alloy steel and undergo rigorous in-house quality assurance processes to ensure that they meet our exacting standards and clients’ needs, as well as industry requirements. In addition, each product produced by CalScrew is traceable and subject to our own quality guarantee.
When combined with our stringent in-house QA processes, our state-of-the-art communications system provides clients with real-time updates on their order, giving them full confidence that the components that we deliver to their warehouse or production line will be exactly as they specified, and delivered when expected.
