50Pcs M6 Square Nut, 304 Stainless Steel, M6 x 1.0

When you need a nut that won’t spin in wood, plastic, or aluminum extrusion, standard hex nuts often fail. Their round shape allows them to rotate when you tighten the bolt, making assembly frustrating and insecure. The LIZIFEQZ 100-Pack M4 Square Nuts solve this problem with a square design that grips the surrounding material, providing a stable, anti-rotation embedment for countless applications. **Square Shape Locks in Place** – The **m4 square nut for t slot track** features four flat sides and sharp corners. When pressed into a matching square hole or tapped into a slightly undersized round hole in wood or plastic, the corners bite into the material, preventing the nut from spinning. This is essential for workbench fixtures, T-slot assemblies, and embedded nut applications where access to the back side is impossible. **304 Stainless Steel – Rust Proof & High Tensile** – Crafted from 304 stainless steel, these **stainless square nut for bench construction** are **rust proof** and highly resistant to corrosion. Whether you are building outdoor workbenches, shop fixtures, or marine equipment, these nuts will not rust or degrade over time. The **high tensile** strength ensures they can handle clamping forces without stripping or deforming. **Prevents Rotation in Wood** – The primary advantage of a square nut is that it **prevents rotation in wood**. Drill a 7mm square hole (or use a 6.5mm round hole and tap the nut in with a hammer), insert the nut, and tighten your M4 bolt. The nut will stay exactly where you put it. This is ideal for making wooden jigs, bench dogs, hold-down clamps, and custom fixtures where you need a reusable threaded hole. **Weldable & Versatile** – These nuts are **weldable** (though typically used as embedment nuts). They are perfect **for machinery and fixtures** where you need a low-profile, anti-spin nut. Use them as sliding nuts in 80/20 aluminum T-slot profiles, as heat-set inserts for 3D printed parts (melt them into the plastic with a soldering iron), or as capture nuts inside square tubing. **Home Improvement & Professional Use** – From **home improvement** projects like building shelving, repairing furniture, or constructing a garden workbench, to professional applications in machine shops and assembly lines, these M4 square nuts deliver reliable performance. The 100-piece bulk pack gives you an ample supply for multiple projects. **Key Applications:** - Embedding into wooden workbench fixtures and jigs - Sliding nuts for T-slot aluminum extrusion (40 series, 20 series) - Heat-set inserts for 3D printed parts (PLA, ABS, PETG) - Captive nuts inside square tubing or rectangular profiles - Furniture assembly (hidden nut connections) - Drone and RC vehicle motor mounts - Eyeglass frame hinge repairs (using M4 screws) **Product Specifications:** - Product Type: Square Nut / Embedment Nut - Thread Size: M4 x 0.7 (Metric Coarse) - Square Dimensions: 7mm x 7mm (0.276 x 0.276 inches) - Thickness: Approximately 3.5mm (0.138 inches) - Material: 304 Stainless Steel - Finish: Polished - Rust Resistance: Yes - Quantity: 100 pieces per pack **What’s in the Box:** - 100 x M4 Stainless Steel Square Nuts (7mm x 7mm) Stop struggling with spinning hex nuts in wood and plastic.
