【Product Description in English】
The central threaded screw serves as a critical connecting component in geodetic instrumentation systems, specifically designed to securely interface theodolites, total stations, levels with tripod assemblies. Manufactured from high-strength alloy through precision machining, this accessory features oxidation-resistant surface treatment that effectively withstands corrosion caused by humidity and salt spray in harsh outdoor environments, ensuring long-term operational reliability.
The dual-thread innovation enhances engagement accuracy while increasing frictional resistance at contact surfaces, significantly reducing displacement risks caused by operational vibrations. The integrated pressure buffer pad, crafted from wear-resistant silicone, evenly distributes equipment weight and prevents scratches on instrument bases caused by metal-to-metal contact. Optimized screw rod length and pitch ratio enable single-handed installation/removal operations, substantially improving field work efficiency.
This component demonstrates consistent performance across diverse applications including structural monitoring, geological surveys, and civil engineering projects. The anti-loosening groove design allows secondary reinforcement using standard wrenches, meeting requirements for extended continuous operation. Rigorous quality control ensures dimensional stability within temperature extremes (-20℃ to 60℃), maintaining functionality in high-altitude and polar climate conditions.
Compatibility with major tripod models and measurement instruments makes it a versatile solution for cross-brand equipment integration. Maintenance-friendly design requires only periodic lubrication to preserve optimal performance. The product embodies practical engineering considerations that balance structural durability with user ergonomics, providing dependable support for precision measurement tasks across multiple industries.
