High-strength steel T-nuts are precision fasteners for heavy-duty aluminum extrusion assemblies, made from carbon or alloy steel. Available in hammer-head or square profiles, they provide post-assembly drop-in installation, self-aligning locking, and high torque resistance. Ideal for CNC frames, robotic systems, automotive rigs, solar mounts, and workstations, they fit 2020–4545 series profiles with M3–M12 or fractional threads. Factory-sourced for bulk or custom OEM orders, they pair with bolts, brackets, gussets, and locking accessories for durable, vibration-resistant modular structures.
