Two-End Stud Bolt
Products Description
The Two-End Stud Bolt is a critical mechanical connection fastener within new energy power electronic equipment. Unlike ordinary single-ended bolts, this fastener features complete threaded structures at both ends, enabling a rigid connection between two independent components without additional nesting. Within large-scale new energy systems such as energy storage converters, high-voltage relays, and new energy electronic control assemblies, it performs core functions including module positioning, component locking, conductive auxiliary support, and structural interconnection. As a system-level connection medium, it connects multiple sub-components such as the housing, busbar components, and electromagnetic actuators, ensuring the entire equipment maintains dimensional accuracy under long-term operating conditions.
Key Product Features and Functions
Double-Thread Locking Function
As a Double-Thread Screw, both ends operate independently, enabling boltless interconnection of two separate components.
01
Mechanical Positioning Function
Utilizing the Twin-End Screw, the fixed spacing between two assembly components is precisely controlled, maintaining safe electrical clearance within the new energy module.
02
Vibration Buffer Support
The Twin-End Bolt evenly transmits assembly preload, reducing stress concentration at connection points due to equipment vibration.
03
Structural Load-Bearing Support
The Double-Headed Machine Screw can bear the self-weight of the busbar assembly and electromagnetic components, sharing the load-bearing pressure on the casing.
04
Modular Compatibility
The Two-Threaded Bolt supports universal selection for multiple electrical control devices on the same platform, facilitating platform-based product design for system integrators.
05
Manufacturing Process
Cold Heading
A multi-station cold heading machine forms the rod and end preforms of the M8 Double Ended Dowel Screw in one step, ensuring dimensional consistency.
Thread rolling
Threads are machined using a planetary thread rolling machine, resulting in a smooth, tear-free tooth surface. The rolled thread surface generates compressive stress, improving fatigue resistance.
Heat treatment
Double-Ended Hex Bolt undergoes carburizing or tempering, achieving a hardness uniformity of HRC±2.
Surface treatment
An automated plating line ensures precise control of plating thickness using the Double-Ended Machine Screw.
Industry Application Cases
| Distributed Photovoltaic Rooftop Systems | In commercial and industrial rooftop photovoltaic projects, the Dowel Screw is used to secure aluminum alloy guide rail systems to wooden purlins. The self-tapping end screws into the purlin to form an anchor, while the machine-threaded end connects to the guide rail via an L-shaped bracket. |
| Energy Storage Container Systems | The installation and securing of battery modules, PCS, and thermal management equipment inside energy storage containers requires numerous fasteners. Double Ended Socket Screws are used to secure the equipment brackets to the container floor or frame, bearing the combined loads of transport vibration and operational thermal cycling. |
| Power Electronics Cabinets | In power electronic equipment such as inverters, UPS, and DC power supply cabinets, Hanger Bolts are used to secure power modules, heat sinks, and busbar supports to the cabinet frame. Their two-end connection allows for maintenance from the front of the cabinet without disassembling the rear mounting structure. |
| Charging Pile Infrastructure | The installation and securing of internal electrical components to the casing of charging piles requires a balance between structural strength and electrical safety. Lead Screws provide reliable mechanical connections while meeting the corrosion resistance requirements of outdoor environments. |
