Brass hexagonal hollow bolt, hollow threading screw, air passage bolt, hexagonal hollow bolt

1.Excellent material performance

Made of high-quality brass material, with natural rust and corrosion resistance, suitable for moisture, acid and alkali prone oxidation conditions; Simultaneously possessing good electrical and thermal conductivity, suitable for special electrical and fluid scenarios.

2.Practical structural design

The hexagonal head is compatible with a universal wrench/socket, making installation and disassembly convenient; The screw is designed with full thread and hollow through-hole, which can achieve special functions such as threading, ventilation, liquid circulation, and weight reduction. It is a customized fastener that cannot be replaced by ordinary solid bolts.

3.Stable precision machining quality

Through CNC turning and integrated molding, the thread accuracy is high, the coaxiality is good, the thread bite is smooth, and it is not easy to slip teeth; The surface is free of burrs and the dimensional tolerance is controllable, which can meet the assembly requirements of precision equipment.

4.Widely applicable scenarios

It can be applied to multiple fields such as electrical equipment, pneumatic/hydraulic systems, instruments and meters, outdoor equipment, etc. It supports non-standard size customization and can quickly match customers’ special assembly needs.

5.Low long-term usage cost

Brass material is wear-resistant and resistant to rust and aging. Compared to carbon steel bolts, it does not require additional electroplating and rust prevention treatment, reducing maintenance and replacement costs and having a longer service life.
