Brass Knurled Adjustment Knob Cap

This precision-machined brass adjustment knob cap features a structure combining a hemispherical base with a cylindrical head, topped with a standard straight knurling pattern for anti-slip performance. Designed for fluid control components or mechanical interfaces requiring frequent manual adjustment, the knurled texture increases finger friction, ensuring precise and effortless torque transmission even in damp or oily environments.

The component body is CNC turned from solid brass bar stock, with strict control over the coaxiality between the hemispherical and cylindrical surfaces, as well as the uniformity of the knurling. The diamond-patterned top is formed using high-precision knurling processes, resulting in clear, consistent-depth textures that enhance the metallic aesthetic while eliminating the risk of sharp edges. The bottom typically features internal threads or snap-fit slots (customized per drawing) for secure connection to valve stems or adjustment screws.
