High Precision CNC Machined Brass Fastener, Brass Screw for Equipment Assembly Connection
Product Overview
High Precision CNC Machined Brass Fasteners are custom precision threaded connection parts manufactured by professional CNC turning and finishing processes. Different from ordinary stamping and standard screws, these brass fasteners feature ultra-high dimensional accuracy, smooth surface and precise thread matching. Made of high-quality brass material, the products integrate corrosion resistance, oxidation resistance and excellent ductility, serving as ideal fastening and connection accessories for high-precision equipment, electronic devices, instrumentation and industrial mechanical assembly.
Core Product Advantages
Premium Brass Material Properties
Adopting high-purity brass raw materials, the fastener has stable metal performance, good toughness and no brittle fracture. It features excellent rust-proof and anti-corrosion capacity, adapting to humid, indoor and lightly corrosive working environments. In addition, brass has good electrical conductivity and thermal conductivity, which meets the special assembly requirements of electrical and precision electronic equipment, with long service life and stable overall performance.
High-Precision CNC Integrated Machining
Processed by advanced CNC precision machine tools, every brass screw is strictly controlled in tolerance, flatness and concentricity. The whole body has no burrs, scratches or dimensional deviations. Compared with conventional fasteners, CNC machined brass screws achieve higher assembly accuracy and better product consistency, fully meeting the matching standards of high-end precision equipment.
Accurate Thread & Stable Connection
The thread is formed by precision rolling and fine tapping technology, with uniform pitch, neat tooth shape and smooth meshing. It can be tightly matched with standard threaded parts, ensuring smooth installation and disassembly. The thread is not easy to slip or wear after repeated use, maintaining continuous and stable locking force to avoid loose equipment connection.
Diversified Customization Support
We support full non-standard customization according to customer drawings and samples, including special head shapes, thread specifications, rod lengths, grooving, hole positions and special-shaped structural designs. Whether prototype trial production, small-batch customization or large-batch mass production, all personalized processing demands can be perfectly satisfied.
