To handle peak-season concentrated delivery and EPC urgent orders, the solar fastener range has doubled 8.8-grade dacromet bolt stock in M8-M16 with matching nuts and washers.
Grade 8.8 dacromet bolts balance strength and corrosion resistance, with 720+ hours salt spray and no hydrogen risk—mainstream for PV racking and module clamps. With doubled stock, standard urgent orders ship within 1-2 days.
Dacromet flange nuts, spring/flat washers and stainless grounding washers are stocked in parallel for one-stop racking fastener supply.
Each batch provides material certificates, coating thickness reports and torque coefficient sampling for project owner audits and site re-inspection.
The solar fastener range welcomes EPC, racking maker and owner inquiries.
