I. Product Overview

This double-head six-sided limit copper bolt is made by CNC turning and milling a high-quality brass rod into an integrated one-piece structure. The central six-sided positioning platform is paired with double-threaded ends, ensuring a seamless one-piece design. The hexagonal platform allows for spanner holding and rotation prevention, accurately controlling assembly spacing to achieve isolation and support of two parts. The brass material excels in electrical and thermal conductivity, meeting both mechanical fastening and circuit conduction requirements.
Available in a variety of materials such as brass, stainless steel, and aluminum alloy, thread specifications, screw length, and hexagon dimensions can be customized according to customer drawings or physical samples. Both small batch trial orders and long-term large-scale supply can be undertaken, with strict inspection of factory-threaded parts and dimensional accuracy.

Chapter II: Core Highlights of Craftsmanship and Workmanship

1. Integrated turning and milling for one-piece forming, high overall strength
   Whole piece one-time cutting processing, hexagonal limit block and both ends thread integrated into one, without welding joints, even stress distribution, easy to tighten without deformation or breakage.
2. Precision standard external thread, firm grip, not easy to slip off
   Threaded one-time rolling car forming, full and regular tooth shape, high matching degree with nuts, still tight and stable after multiple disassemblies.
3. Central hexagonal limiting structure, easy and efficient assembly
   Hexagonal shape for easy wrench gripping and fixation; effective anti-rotation during assembly; precise control of component isolation gaps; enhancing batch assembly consistency.
4. Full-range deburring treatment, free from sharp edges and corners
   All threads and hexagonal edge positions are deburred andPassivation, making assembly less likely to scratch circuit boards, plastic casings, and other precision components.

Section 3: Optional Customizable Raw Materials

1. H62 Brass (Recommended)
   Easy-to-machine, balanced conductivity, high cost-performance ratio, the first choice for electronic conductive isolation bolts.
2. Cupronickel
   Optimal electrical conductivity, suitable for high current loop connection scenarios.
3. Stainless steel
   Corrosion and rust resistant, suitable for humid environments; does not require high conductivity under only mechanical fastening conditions.
4. Aluminum alloy
   Lightweight, select low-load positioning support for lightweight instruments.

4. Optional Surface Treatment Processes

• Copper brass original color polishing: Best conductivity, suitable for general electronic components.
• Nickel plating: Prevents copper from oxidizing and turning black, enhancing rust resistance and durability.
