Aluminum Knurled Thumb Screw 12.8×25mm CNC Precision Machined Custom Anodized Colors

Product Description:

This 12.8×25mm aluminum thumb screw is precision-machined from high-quality aluminum alloy, offering a lightweight structure, corrosion resistance, and a clean, professional appearance. Manufactured using advanced CNC turning techniques, the surface is smooth and the internal thread is accurate, ensuring a secure and reliable fit.

The exterior features a tapered head and vertical knurling for enhanced grip and anti-slip performance, making it ideal for manual fastening or frequent assembly/disassembly. The knurled pattern is uniform and clear, improving both functionality and industrial aesthetics. The screw is supplied in raw aluminum finish but can be customized with anodizing, sandblasting, or other surface treatments upon request.

With a standard outer diameter of 12.8mm and height of 25mm, this component is widely used in fixtures, electronic enclosures, communication hardware, automation equipment, and lightweight structural assemblies. The use of pure aluminum allows excellent weight control and thermal conductivity.

We offer flexible OEM/ODM customization including thread size, dimensions, surface finish, and color options. All products are ISO9001 certified and thoroughly inspected before shipment to ensure consistency and quality. We also support custom packaging, laser marking, and bulk orders.
