This Schletter Hanger Bolt Kit fastens PV mounting rails to wood purlin roofs beneath corrugated fibre-cement or trapezoidal sheet metal roofing, where the bolt passes through the roof covering into the timber purlin below.
Supplied pre-assembled, the kit combines an M10 x 200mm hanger bolt with a vulcanised, UV-resistant EPDM sealing washer and three V4A stainless steel flange nuts, giving a single weatherproofed part ready to drive straight into the purlin.

Key Features
Pre-Assembled for Speed
Arrives with the bolt, EPDM seal and three flange nuts already assembled, reducing on-site handling of loose parts.
Vulcanised UV-Resistant EPDM Seal
The vulcanised EPDM sealing washer is rated for long-term UV exposure, maintaining a weatherproof seal at the roof penetration point for the life of the installation.
Three V4A Stainless Steel Flange Nuts
Includes three high-grade V4A stainless steel flange nuts, providing secure, corrosion-resistant fixing at the roof and rail interface.
Suited to Corrugated & Trapezoidal Roofs
Designed specifically for corrugated fibre-cement or trapezoidal sheet metal roofing over a wood purlin substructure, a common configuration on UK agricultural and commercial buildings.
Requires Adapter for Rail Connection
Used together with a mounting plate or KlickTop-type attachment (ordered separately) to connect the hanger bolt to the module-bearing rail above.
Consistent With Schletter's Wider Hanger Bolt Range
Shares its fixing principle and seal specification with Schletter's other hanger bolt sizes, so it can be combined confidently with the rest of a Schletter roof-fixing system.
Please Note
Thread lengths on hanger bolt kits can deviate slightly from stated figures, per Schletter's own published guidance. A separate mounting plate or KlickTop-type adapter (sold separately) is required to connect this hanger bolt to a module-bearing rail.

Frequently Asked Questions
What roof types is this hanger bolt kit designed for?
It is intended for wood purlin roofs finished with corrugated fibre-cement sheets or trapezoidal sheet metal, where the bolt is driven through the roof covering into the timber purlin below.
Does the kit include everything needed to connect to the mounting rail?
The kit provides the hanger bolt, EPDM seal and three flange nuts for the roof-side fixing. A separate mounting plate or KlickTop-type attachment is needed to connect the bolt to the module-bearing rail, and is ordered separately.
Is the seal suitable for long-term outdoor exposure?
Yes, the EPDM sealing washer is vulcanised and UV-resistant, intended to maintain a weatherproof seal at the roof penetration for the working life of the installation.
What grade are the included nuts?
The kit includes three V4A stainless steel flange nuts, a higher corrosion-resistance grade suited to long-term outdoor use.
Can I use this on a metal purlin instead of wood?
No, this specific kit is designed for wood purlin substructures. Steel purlin roofs typically use a different self-tapping fastener system; check with our team if you are unsure which is appropriate for your roof structure.
