KD Fasteners, Inc. uses the lightweight and corrosion resistance of aluminum to manufacture a bolt with the best strength-to-weight ratio available – the aluminum heavy hex bolt.

Made with a larger head than standard hex bolts, our aluminum heavy hex bolts are stronger than the average hex bolt and have more pull power. Aluminum heavy hex bolts can be used in the aerospace, aircraft, military, chemical processing, oil and gas, and marine industries.
