The Renusol VarioSole Hanger Bolt M12 x 250 (Part No: R-860007) is a structural fixing designed to secure Renusol VarioSole SE and TriSole mounting systems onto a wooden roof substructure. Made from A2 stainless steel, the bolt combines a metric M12 threaded top section with a wood-cutting tip, joined by an integrated sealing collar that keeps the penetration point watertight once installed.
The hanger bolt is supplied as part of a small hardware set that also includes a hammerhead bolt, hexagon nut, and standard bracket, giving installers everything needed to complete the roof-to-rail connection at each fixing point.

Minimum Screw Penetration
Good to Know: This hanger bolt can be installed without pre-drilling, with the wood-cutting tip creating its own pilot as it's driven in. A minimum screw penetration of 60mm into the timber substructure is required for a secure fixing.
A2 Stainless Steel Construction
Manufactured from A2 stainless steel, providing strong corrosion resistance for a component that sits at the roof penetration point for the system's working life.
Integrated Sealing Collar
A 25mm diameter integrated sealing collar keeps the wood penetration point watertight, without needing a separate washer or sealant applied on site.
Wood-Cutting Tip for No Pre-Drilling
The wood-top screw tip allows installation without pre-drilling, speeding up fixing across multiple penetration points on a roof.
Partial Thread with M12 Metric Top
A partial thread design combines a wood-cutting lower section with an M12 metric thread at the top, giving a standard connection point for the mounting rail bracket above.
91mm Vertical Adjustment
The bolt provides 91mm of vertical adjustment space, helping installers compensate for uneven roof surfaces or varying batten heights.
Complete Fixing Set Included
Supplied with a hammerhead bolt (M8x25), hexagon nut, and a standard M12 bracket, giving a complete connection from timber substructure through to mounting rail.
Important Safety Information: Renusol mounting equipment must not be used with mounting equipment from other suppliers. Doing so would inevitably void the warranty of the mounting system.

Do I need to pre-drill before installing this hanger bolt?
No. The wood-cutting tip allows installation without pre-drilling, though a minimum screw penetration of 60mm into the timber substructure is required.
What does the sealing collar do?
The 25mm integrated sealing collar keeps the wood penetration point watertight without needing a separate washer or applied sealant.
How much vertical adjustment does this bolt offer?
It provides 91mm of vertical adjustment, helping accommodate uneven roof surfaces or varying batten heights.
What comes included with this hanger bolt?
The set includes the hanger bolt itself, a hammerhead bolt (M8x25), a hexagon nut, and a standard M12 bracket — a complete fixing from substructure to mounting rail.
What mounting systems is this hanger bolt compatible with?
It is compatible with VarioSole SE and TriSole product groups.
Can I substitute a different manufacturer's hanger bolt?
No. Renusol mounting equipment must not be used with mounting equipment from other suppliers, which would inevitably void the mounting system's warranty.
