BISS fastening hardware designed to secure components on aluminium T-slot rails, promising durable, corrosion-resistant connections. Installers and solar technicians will gain confidence with the reliability of Heozhuyi T Slot Bolts. Are M8 x 20mm fasteners the right size and specification for your installation?
⚡ At a Glance
- • Material Quality: Nickel-plated stainless steel, high hardness, corrosion-resistant
- • Best for: Mounting solar panels, rails, cable ducts and heavy components on T-slot profiles
- • Not ideal for: Assemblies that do not use M8 T-slots or require specialised non-T fasteners
M8 x 20mm T-slot bolts come with matching hexagon flange nuts in a 20-piece kit. Nickel-plated stainless steel construction improves corrosion resistance for outdoor and industrial use.
Long-term Corrosion Resistance - Thanks to nickel-plated stainless steel
Nickel plating over stainless steel creates a protected surface layer and resists oxidisation. High hardness and careful surface treatment reduce wear on threads during repeated use.
Durable finish keeps fixings usable outdoors and in damp environments, reducing replacement frequency. Suitable for installations exposed to weather or corrosive conditions.
Vibration-resistant Fastening - With hexagon flange nuts and serrations
Flange nuts act as integrated washers and the designed serrations bite into mating surfaces. The serrations increase friction and reduce the tendency for nuts to turn under vibration.
Secure clamping reduces loosening on roofs and mechanical frames, making the set a sensible choice for solar mounts and rail-mounted equipment. Less re-torquing is required after initial assembly.
Quick Positioning and Adjustment - With hammer head T-slot design and clear threads
Hammer head profile allows insertion into aluminium slots and the clear threads enable smooth engagement with nuts. The T-slot form permits sliding along rails for alignment before final tightening.
Components can be repositioned along rails during installation, making setup faster and adjustments simpler. Ideal for jigs, roof racks and systems that need precise alignment.
✨ The 4 Key Reasons for Heozhuyi T Slot Bolts
- M8 x 20mm specification - Ensures predictable fit in standard metric T-slot rails and consistent clamping force.
- 20-piece kit with storage box - Keeps spares organised and ready for multiple installations on site.
- Clear, well-formed threads - Enables smooth tightening and reduces cross-threading risk during assembly.
- Hexagon flange nuts with serrations - Resists loosening under vibration for secure long-term fixing.
