PV Dual Thread Hanger Bolt

Outdoor Grade Integral Forming & Weather-Resistant Thread Rolling Technology

This PV Dual Thread Hanger Bolt produced by Wanluo factory adopts one-piece integral forging and full-automatic precision thread rolling process, with no splicing gaps and uniform overall stress, fully adapting to long-term outdoor wind and rain erosion environment. The wood thread section is optimized with deep tooth and sharp cutting design, which can quickly and stably tap into solid wood and wooden composite brackets without board cracking or loose biting, ensuring stable clamping force for long-term use. The machine thread end adopts industrial standard precision rolling process, with accurate tooth pitch and smooth meshing, perfectly compatible with PV standard brackets, gaskets and lock nuts. The whole bolt undergoes enhanced heat treatment to improve tensile strength and structural toughness, resisting vibration loosening caused by outdoor wind vibration. Adopting outdoor-grade electro galvanizing and thickened anti-rust passivation treatment, it effectively delays oxidation and corrosion, meeting the long-service-life operation requirements of photovoltaic power stations.

Outdoor PV Adaptability & Wind-Resistant Stable Connection Advantages

1. Professional PV outdoor anti-loosening optimization. Different from ordinary indoor furniture hanger bolts, this solar-specific double-thread bolt is optimized for outdoor wind vibration environment. The deep-tooth wood thread increases the contact bite area with wooden brackets, effectively solving the problem of loose fastening caused by long-term wind blowing and vibration of photovoltaic equipment.

2. Wood-metal cross-material efficient connection. The dual-thread integrated structure perfectly connects wooden support beams and metal PV brackets, realizing one-bolt rapid assembly. It eliminates the trouble of matching multiple fasteners, simplifies the on-site construction process of photovoltaic projects, and greatly improves the installation efficiency of power stations.

3. Concealed installation reduces outdoor operation risks. The headless flat structure avoids exposed bolt protrusions, effectively reducing wind resistance of photovoltaic supports, preventing dust and rainwater from accumulating at fastener positions, and avoiding local rust corrosion and structural wear, which prolongs the overall service life of PV supports.

4. Enhanced weather-resistant and anti-aging performance. Adopting thickened anti-corrosion surface treatment technology, it resists ultraviolet aging, rain erosion and temperature alternation in outdoor environments. It maintains stable structural strength and fastening performance in long-term open-air photovoltaic power station operation.

5. Project-oriented customized matching capability. It supports personalized size and process customization for different wooden PV support specifications and regional climatic environments. Stable batch quality and targeted outdoor performance make it a dedicated supporting fastener for wooden photovoltaic power station projects.

FAQ

Q1: What is the difference between PV Dual Thread Hanger Bolt and ordinary double-thread studs? 

A1: PV dedicated hanger bolts adopt outdoor weather-resistant and anti-vibration optimization design, with enhanced thread bite force and anti-corrosion performance. They are specially adapted for long-term outdoor PV support operation, while ordinary hanger bolts are only suitable for indoor furniture assembly and cannot resist outdoor harsh environments.

Q2: Is it suitable for all wooden photovoltaic supports? 

A2: Yes. It is compatible with solid wood brackets, wooden composite profiles and wood-structured PV frames. The optimized anti-cracking thread design can adapt to various wooden support materials, achieving stable and firm fastening effect.

Q3: Can it withstand long-term outdoor wind and rain erosion? 

A3: Absolutely. Equipped with outdoor-grade anti-rust and anti-aging coating, the bolt has excellent weather resistance, which can effectively resist wind vibration, rain erosion and ultraviolet radiation, ensuring long-term stable connection of PV supports.

Q4: Does the concealed structure affect the fixing strength of PV brackets? 

A4: No. The one-piece forging structure ensures uniform stress, and the dual-section thread meshing provides super tensile and anti-loosening force. The fastening strength fully meets the load-bearing and wind-resistant safety standards of photovoltaic support structures.

Q5: Can customized specifications meet different PV project requirements? 

A5: Yes. We support customized overall length, thread proportion, surface anti-corrosion grade and logo marking, and can provide targeted fastener matching solutions according to different photovoltaic project design standards.
