DarkoNuts

Built for serious home gym owners, these steel-core rack nuts are fully encased in high-impact TPU to eliminate cracked plastic hardware and prevent rack damage. They’re strong, drop-resistant, and designed to protect your equipment while giving you tool-free adjustability.

Why They’re Different

Traditional 3D printed nuts can split when dropped. Bare steel nuts can chip or dent your uprights. These solve both problems. Each nut features a standard steel core for real strength, completely wrapped in durable TPU. The result is a near-indestructible, rack-safe fastening solution that absorbs impact instead of transferring it to your equipment. Drop them on concrete. Install and remove repeatedly. Accidentally bump your uprights. No cracks. No chips. No scratched powder coat.
