Solar Mounting Fasteners
WT Fasteners supplies a wide range of mounting fasteners for rooftop PV, commercial and industrial PV, and solar mounting systems, including solar hanger bolts, hook bolts, T-bolts, flange nuts, washers and other related connecting parts.

Solar Hanger Bolts
Solar hanger bolts usually have a wood thread or self-tapping thread on one end and a metric machine thread on the other, and can be used to connect roof structures to solar mounting systems.
Common configurations include:
- Hex nuts
- Flange nuts
- Flat washers
- EPDM rubber sealing gaskets
- Metal sealing washers
EPDM seals can help improve sealing performance at rooftop mounting locations.

T-Bolts and T-Nuts
T Bolts and T Nuts are commonly used for connections inside solar rail channels.
Different rails may have different slot widths, slot depths and internal structures, so the head dimensions and structure of T-bolts need to match the rail.
WT Fasteners can provide custom production according to customers' rail dimensions or drawings.
