Secure solar arrays to rooftops, ground mounts, and carports with ​Heavy-Duty Solar Hanger Bolts, engineered for unmatched durability and ease of installation. Featuring a ​stainless steel body with dual-thread design (wood screw tip + ​machine thread), these bolts anchor panels to wood purlins, metal rails, or concrete without pre-drilling, reducing labor time by 35%. Resistant to corrosion, UV degradation, and extreme temperatures (-40°C to 120°C), they maintain structural integrity in coastal, desert, and high-humidity environments.

Compatible with ​IronRidge, ​Unirac, and ​Schletter racking systems, these bolts support ​200+ lbs of vertical load per fastener and meet ​NEC 690, ​UL 2703, and ​IEC 62446 standards. The ​self-sealing EPDM washer prevents water ingress, while the ​galvanic isolation coating eliminates corrosion between dissimilar metals. Ideal for asphalt shingles, standing seam roofs, and ground mounts, these bolts include ​pre-assembled nuts for tool-friendly installation with standard wrenches or impact drivers.
