Solar dual-head bolt

I. Core Product Details
Material: carbon steel Q235B/4.8/8.8/10.9, stainless steel 304/316 (corrosion resistant upgrade)
Specification: thread specification M8-M16, length 30mm-150mm (can be customized), coarse thread/fine thread
Surface treatment: carbon steel (hot-dip galvanized, electro-galvanized, Dacromet), stainless steel (natural color/passivation treatment)
Installation method: matching nut + flat washer/spring washer, direct threaded connection, without welding, suitable for fixing all parts of photovoltaic bracket
Applicable scenarios: distributed roof/ground power station, photovoltaic car shed, BIPV project, used for the connection and fixation of support beams, columns, purlins and component briquettes

II. Key characteristics
High-strength bearing: tensile strength of 8.8/10.9 carbon steel ≥ 800MPa, applicable wind load ≤ 60m/s, snow load ≤ 1.4kN/㎡
Long-acting anti-corrosion: the thickness of hot-dip galvanized layer is 45-85 μm, and 304/316 stainless steel is suitable for coastal salt fog and high humidity environment
Precise adaptation: thread accuracy of 6H grade, tight occlusion, compatible with U-shaped steel/C-shaped steel/M-shaped steel and other bracket accessories
Stable structure: double thread design, uniform stress at both ends, excellent anti-loosening performance
Standardized production: in line with the general standard for installation holes of PV bracket
III. Product Advantages
Efficient installation: direct thread fastening, no need for drilling/welding, improve construction efficiency
Reliable connection: high-strength material + anti-loose matching, long-term use without the risk of falling off, to ensure the stability of the support structure
Multi-environment adaptation: carbon steel + stainless steel material is optional, covering the whole scene from inland to coastal.
Cost economy: standardized mass production, affordable price, supporting supply to reduce procurement costs
Durable and worry-free: the anticorrosive coating is not easy to fall off, and the outdoor service life is 15-25
