High Corrosion Resistance Hollow Brass Ball Head Screw
,Precision CNC Machining Through Bore Spherical Head Screw
,Lightweight Structural Advantage Brass Ball Head Fastener
Hollow Brass Ball Head Screw is a high-precision multi-functional perforated fastener specially designed for lightweight assembly, gas circuit, circuit and mechanical fine fitting scenarios. Different from traditional solid screws, this product features a unique through bore hollow structure and smooth spherical ball head design, perfectly integrating connection fixing, weight reduction, penetrating conduction and flexible fitting functions.
Made of high-purity brass material and processed by one-time CNC precision turning, the screw boasts smooth burr-free inner and outer surfaces, accurate hole diameter tolerance and seamless spherical radian. The hollow through bore design realizes pipeline penetration, wire routing and airflow conduction while completing mechanical locking. The polished spherical head avoids rigid friction and scratch damage during contact and rotation, ensuring flexible fitting and stable assembly.
Widely used in precision mechanical fittings, electronic equipment, instrumentation and adjustable assembly structures. We provide full non-standard custom machining for bore diameter, screw size, ball head radian and overall structural specifications.
- Hollow Through Bore Design: Unique penetrating hollow structure supports wire routing, airflow circulation and pipeline penetration, realizing dual functions of fixing and conduction, greatly expanding application scenarios.
- Smooth Spherical Ball Head: Precision polished arc ball head eliminates sharp edges, reduces contact friction, allows flexible angle fitting and avoids scratch damage to matching parts.
- Premium Brass Material Performance: High-quality brass features excellent electrical conductivity, thermal conductivity, corrosion resistance and oxidation resistance, suitable for long-term use in precision electronic and mechanical environments.
- Lightweight Structural Advantage: Hollow design effectively reduces overall assembly weight without affecting fixing stability, meeting lightweight assembly requirements of precision equipment.
- Precision CNC Machining: Strict dimensional tolerance control, uniform inner hole wall and standard thread ensure smooth assembly, no jamming and high matching accuracy.
- Full Non-standard Customization: Support custom inner bore diameter, outer diameter, length, ball head size and special-shaped hollow structure according to drawings and samples.
