OEM CNC Precision Hollow Threaded Studs Single or Double End Stud

설명

What Are Hollow Threaded Studs?

Hollow threaded studs are specialized fasteners with a hollow core and threaded ends, designed for applications requiring lightweight yet strong connections, fluid or gas passage, or electrical wiring pathways. They combine the functionality of a traditional stud with the added benefit of an internal cavity.

Materials

Hollow threaded studs are commonly made from:

• Stainless Steel (e.g., 304, 316 for corrosion resistance)

• Carbon Steel (often zinc-plated for durability)

• Aluminum (lightweight applications)

• Brass (electrical or plumbing uses)

Surface Treatments

To enhance performance, hollow threaded studs may undergo:

• Zinc Plating (anti-corrosion)

• Hot-Dip Galvanizing (heavy-duty protection)

• Passivation (for stainless steel, improving rust resistance)

• Anodizing (for aluminum, increasing hardness and color options)

Specifications

• Diameter: Ranging from M4 to M30 or custom sizes

• Length: Varies based on application (typically 20mm to 500mm)

• Thread Type: Metric, UNC, UNF, or custom threading

• Hollow Bore Size: Adjustable depending on fluid/wire requirements

Applications

• Automotive & Aerospace: Lightweight fluid transfer systems

• Electrical & Solar: Conduit for wiring in junction boxes

• Plumbing & HVAC: Gas or liquid flow in compact assemblies

• Industrial Machinery: Pneumatic or hydraulic line connections

Excellent Case: Solar Panel Mounting System

A leading solar energy company integrated stainless steel hollow threaded studs (M10, 316 grade, passivated) into their panel mounting racks. The studs served dual purposes:

1. Structural Support: Securely fastened solar panels to aluminum frames.

2. Cable Management: The hollow core allowed internal routing of electrical wires, protecting them from weather and reducing clutter.

This innovation cut installation time by 20%, improved system longevity by preventing cable exposure, and maintained a sleek, low-profile design—showcasing the studs’ versatility in renewable energy solutions.
