Fastener

Custom-Made Special-Shaped Fasteners

The porous flange is a ring-shaped connecting piece with multiple bolt holes, used for the sealing connection of pipes, valves or equipment.

Aluminum Alloy Fastener

Aluminum alloy hexagonal hollow double-headed screws are lightweight and high-strength fasteners made of aluminum alloys (such as 6061-T6 or 7075), which have both corrosion resistance and low weight advantages. The two ends are taper threaded, which enhances the connection sealing and vibration resistance, and the inner holes at both ends are different in diameter, making it easy to adapt to different installation needs.
