Structural and Heavy Hex Nuts

South Coast Fasteners, Inc. supplies structural and heavy hex nuts that are built tough for demanding, high-strength jobs in construction, steel fabrication, and infrastructure projects. These nuts have a thicker body and wider flats than regular hex nuts, giving them a bigger surface area to bear heavy loads. They’re commonly paired with structural bolts and anchors to keep critical connections strong and secure. Made to meet strict industry standards, these nuts deliver reliable performance when it matters most.
