Products Description

Upgrade your power and signal connections with our high-performance Screw on Terminals, featuring pre-assembled screws and terminal frames for reliable, quick, and vibration-resistant wire connections. Designed specifically for applications that demand robust mechanical locking and stable conductivity, these Screw Clamp Type Terminals are widely used in circuit breakers, switches, solar fuse holders, and industrial meters.
Key Features & Benefits
Pre-Assembled for Efficiency
Our Terminal Screw Blocks come with factory-assembled M3/M4 screws and precision-formed terminal frames, significantly reducing assembly time in automated or manual production lines.
01
Secure Screw Clamp Design
The Screw Clamp Type Terminal structure ensures tight wire fastening and excellent anti-loosening performance, making it ideal for applications subject to vibration or thermal cycling.
02
High Conductivity Materials
Frames are made from high-conductivity copper, brass, or tin-plated iron, ensuring low resistance and high current capacity for demanding electrical environments of the Breaker M4 Screw Terminal Block.
03
Compact & Space-Saving
Slim design supports compact terminal arrangements in circuit breaker enclosures, switchboards, and smart home panels without sacrificing performance for Circuit Meter Iron Terminal Crimping Frame.
04
Customizable Wire Entry & Torque
Support for various crimping styles and wire gauge ranges with torque-optimized Terminal Screw Block lengths and head types (Phillips, slotted, hex).
05

Material and Manufacturing Excellence
Premium Material Selection
We offer Screw on Terminals in a variety of materials to suit different performance requirements. Brass terminals provide a balance of conductivity and corrosion resistance, copper terminals offer superior electrical performance, and stainless steel terminals are ideal for applications requiring high mechanical strength and durability.
Precision Manufacturing Process
Each Screw Clamp Type Terminals undergoes a meticulous manufacturing process. The screws are precision-machined to ensure a perfect fit with the terminal blocks, while the blocks themselves are manufactured to precise electrical specifications. We utilize advanced CNC machining and other precision manufacturing technologies to maintain strict tolerances, ensuring high-quality and reliable performance.
