Square Double Thread Connecting Bolt, Dacromet Middle Square Column Adjustment Screw

Product Introduction

Square double thread connecting bolt is a special adjustable connecting fastener. It is made of high-strength alloy steel through integrated cold forging process, with dense internal metal texture and strong tensile and shear resistance. The square middle section is convenient for wrench clamping during installation, which greatly improves assembly efficiency and avoids slipping during adjustment. Both ends are rolled with precise standard threads, which can be matched with standard nuts to connect two groups of workpieces and adjust the assembly distance freely. The Dacromet anti-corrosion coating on the surface can effectively resist oxidation, salt spray and chemical corrosion, and can maintain stable performance in humid and outdoor working environments for a long time. The overall structure is solid, and it will not loosen or shift under long-term mechanical vibration.

Product Advantages

1. Middle Square Column Design: Easy wrench clamping, convenient length adjustment during assembly.

2. Double-End Full Thread Structure: Two-way docking connection, freely adjustable assembly spacing.

3. Dacromet Anti-Corrosion Coating: Superior salt spray resistance, long service life in harsh environments.

4. High-Strength Alloy Steel: Strong load-bearing capacity, anti-fatigue and anti-vibration, not easy to deform.

5. Customized Processing Service: Custom square size, thread diameter, total length and thread length according to drawings.
