Product Picture
The GB806 knurled thumb nut is a hand-tightened fastener designed for applications requiring frequent manual adjustment or disassembly. It features a raised cylindrical head with a knurled surface, allowing for quick and easy hand tightening and loosening.
I. Product Materials and Processing
The GB806 knurled thumb nut is crafted from high-quality 304 stainless steel, with a salt spray resistance of 24-48 hours. Its excellent rust resistance makes it ideal for outdoor or corrosive environments. Precision-turned and knurled, the surface features a 1.2mm-spaced diamond-shaped anti-slip pattern.
II. Structural Features and Performance Advantages
Raised head design: The head is twice the height of a standard nut, providing a larger contact area and more comfortable force application.
Double-sided knurling: Utilizing a 45° cross-knurling process, the anti-slip performance is 100% improved compared to ordinary smooth-faced nuts.
Precision-fit structure: The internal threads are precisely machined on a CNC lathe, ensuring axial play within 0.05mm when mated with standard bolts, ensuring secure tightening.
