Solar Hanger Bolts: M10 & M12 Deep Purlin Anchor Guide
Stainless steel dual-threaded hanger bolts penetrate insulated sandwich panels and corrugated sheets to anchor into steel or timber purlins.
4 Key Engineering Selection Criteria for Solar Hanger Bolts (Dowels)
M10 vs M12 Diameter Sizing
M10 for standard spans; M12 for deep insulation layers (>150mm) and high wind/snow zones.
Vulcanized EPDM Sealing Ring
Pre-fitted EPDM washer compresses firmly around sheet crowns ensuring 100% watertight seal.
Triple Flanged Nut Locking
Allows independent height adjustment of the L-foot adapter plate.
Steel & Timber Substrates
Fine metric thread on top, coarse wood thread or self-tapping steel thread on base.
Export Pricing & Logistics Procurement Tips
Supplied as complete sets (hanger bolt, 3 nuts, EPDM washer, aluminum L-adapter plate) in boxes of 50 pcs.
