Corrosion-Resistant DIN 125A 304 Stainless Steel Flat Washers

Our customized bicycle bottom bracket nut is designed for high-performance locking and durability. Featuring a serrated flange nut bicycle design, it effectively prevents loosening even under high-intensity vibration during cycling. This crankset locking screw is precision-machined from high-strength steel with professional surface treatments (black oxide or zinc plating) for superior rust resistance. Ideal for universal repairs of center axes and MTB cranksets, it ensures a secure fit and smooth power transfer for your bike.

As a top-tier precision machined parts supplier, we support 3-day prototyping and 7-day batch delivery. Our in-house lab ensures 100% strict quality control, backed by ISO 9001/14001. We provide technical DFM feedback and manufacturing scale for global supply chains.

Accelerate your product development with our comprehensive custom cnc milling services. Our facility is optimized for cnc machining prototypes, allowing for rapid iteration of complex housings, structural brackets, and intricate industrial components. We handle a vast range of materials, specializing in anodized cnc aluminum parts with vivid surface finishes, as well as precision-turned stainless steel rods and custom polymer components. Our capabilities include high-gloss mirror polishing and multi-part assembly fitment. Whether you need a single functional prototype or a bridge to mass production, we provide DFM feedback and 100% inspection to ensure every dimension matches your STEP/IGS files.

Source hardware directly from a trusted precision turned components manufacturer. We produce custom knurled thumb screws and diverse brass cnc machining parts, including nozzles and standoffs. Using CNC lathes and Swiss technology, we achieve tight tolerances and intricate knurling patterns (straight or diamond). We also process stainless steel and aluminum into ball studs and turned fittings. Whether for prototypes or production, we offer ready stock and full customization. Nickel plating and passivation are available for longevity.
