Yeasing T Bolt Set provides M8 T-slot hammer head bolts plus matching flange nuts for aluminium extrusion assemblies, promising durable, rust-resistant fastening. Installers and DIYers gain quicker assembly and fewer trips to the hardware store. Is the kit robust enough for rooftop solar work and repeated installations?
⚡ At a Glance
- • Fastening Strength: Thickened T-head and M8 threading deliver secure clamping in T-slot profiles
- • Best for: Installers and hobbyists assembling aluminium extrusion frames and solar mounts
- • Not ideal for: Situations requiring countersunk fasteners or stainless grades higher than A2-70
A2-70 stainless steel hammer head bolts with nickel plating, supplied as a 10-screw and 10-nut kit. Drop-in design suits aluminium long holes and T-slot guide rails for PV and structural assemblies.
Long-lasting corrosion resistance - thanks to A2-70 stainless steel with nickel plating
A2-70 stainless steel forms a corrosion-resistant alloy while nickel plating creates an additional surface layer that slows oxidation. The combination reduces the risk of surface rust in damp or outdoor conditions.
Improved longevity for rooftop and outdoor installations, lowering replacement frequency and maintenance effort.
Faster assembly - with drop-in hammer head T-slot design
Hammer head bolts insert directly into aluminium long holes and seat in T-slots, allowing tightening from the front without sliding components apart. The M8 thread engages with included flange nuts for immediate clamping.
Speeds up framework construction and solar panel fastening, reducing time on ladders and in workshops.
Ready-to-use kit - with matching M8 flange nuts and exact dimensions
Kit contains ten M8 x 20mm hammer head screws and ten M8 flange nuts. Specified dimensions include 8mm diameter, 20mm thread length, 24mm total length, 10mm head width, 4mm head thickness and 23mm head length.
Eliminates the need to source compatible nuts separately, making small projects and repairs straightforward.
