Product Description
Brass Spring Cap CNC Screw
Precision Machined Brass Spring Loaded Cap Screw, Non-standard Custom Hardware Fastener
Product Overview
Brass Spring Cap CNC Screw is a high-end precision elastic hardware fastener integrating brass body and built-in spring structure. Different from ordinary fixed screws, this spring loaded cap screw adopts one-piece CNC precision turning molding, with integrated spring telescopic function, realizing flexible telescopic pressing, buffer positioning and elastic locking assembly.
Made of high-quality brass material, the product features excellent electrical conductivity, anti-corrosion, oxidation resistance and non-magnetic performance. The smooth burr-free surface and precise tolerance ensure stable elastic compression and reset effect during repeated use. It effectively solves rigid extrusion, loose contact and assembly gap problems of precision equipment connection.
Widely used in electronic instruments, communication equipment, electrical assemblies and precision mechanical adjustment structures. We provide full non-standard custom machining for screw size, cap shape, spring stroke and structural appearance.
Key Features
- Elastic Spring Loaded Design: Built-in spring telescopic mechanism provides automatic buffering and elastic pressing, avoiding rigid collision and assembly pressure damage for precision parts.
- Premium Brass Material Performance: High purity brass raw material delivers outstanding conductivity, anti-oxidation and anti-corrosion properties, suitable for electrical and precision instrument environments.
- Precision CNC Machining: Strict micron-level tolerance control, smooth cap surface and accurate thread, ensuring flexible telescopic movement without jamming.
- Stable Reset & Locking Effect: Uniform spring force ensures consistent compression and reset, maintaining stable contact and positioning after long-term repeated assembly.
- Vibration Resistance & Anti-loose: Elastic buffer structure absorbs equipment vibration, effectively preventing loosening and poor contact caused by mechanical oscillation.
- Full Non-standard Customization: Support custom diameter, length, spring stroke, cap appearance and special-shaped structure according to drawings and samples.
