Suitable for electronic repairs, DIY projects, machinery, and precision instruments like computer cases, drones, and measuring tools, these flat knurled thumb nuts secure components with ease. Their female thread design and thickness ensure stable connections in furniture assembly, automotive parts, and industrial equipment requiring manual adjustments.
This pack includes 4 Pcs of M4x12x5.4mm knurled thumb round nuts, crafted from durable 304 Stainless Steel material. Each nut has a 12mm / 0.47" diameter and 5.4mm / 0.21" height, offering a robust clamping force. The thread pitch is 0.7mm / 0.03". The knurled surface ensures a non-slip grip.
Crafted from 304 stainless steel, these nuts resist corrosion and wear, offering lasting durability. They combine high strength, heat resistance, and noise reduction for reliable performance in harsh environments. The diamond-knurled flat head provides superior grip for tool-free tightening, while the height and thread suit tight spaces.
Align the nut's female thread with the target screw or bolt. Hand-tighten until snug, using the knurled edges for grip. No tools required. Ensure the flat head sits evenly against the surface to distribute pressure and prevent loosening. For frequent adjustments, periodically check the tightness.
Verify that the thread size and height match your project requirements before installation. Avoid over-tightening to prevent thread damage. Not recommended for heavy-load structural applications.
