· Product Overview
Introducing the YITECH Precision Stainless Steel T-Nut Washers (Square-Head Insert Nuts) — a high-performance fastening solution designed for secure, vibration-resistant mounting on extruded aluminum profiles (e.g., 2020, 3030, 4040), sheet metal, or composite panels. Each unit features a flat circular washer base with a centrally integrated square-headed nut, enabling tool-free insertion into T-slots and reliable clamping with standard hex bolts.
Crafted from A2-70 / 304 stainless steel, these T-nuts combine superior corrosion resistance, high tensile strength, and long-term durability — ideal for industrial automation, robotics, CNC machinery, and demanding DIY projects. The smooth, burr-free surface and precise geometry ensure easy sliding into T-grooves while preventing rotation under load. Unlike plastic or low-grade steel alternatives, our T-nuts maintain integrity even in humid, outdoor, or high-vibration environments.
Perfect for modular framing systems where repeated assembly/disassembly is required — no welding, drilling, or adhesives needed.
· Core Specifications
| Feature | Specification |
|---|---|
| Material | AISI 304 Stainless Steel (A2-70 grade), fully annealed for optimal thread engagement |
