ButtonHex socket head cap screw(TKS(Tokosha(SSS(Coarse Steel Trivalent black(Black) 3 X 8 Pitch 0.5
Screws ideal for ALC (Autoclaved Lightweight Concrete) – also suitable for wood
●The special pitch ensures that only the shank and tip sections advance at equal intervals, preventing damage to the mating material caused by double-thread engagement common with conventional screws. In ALC applications, the screw drives smoothly without breaking the cellular structure, and the joint achieves a tight, flush connection without lifting.
●The full thread design eliminates free-spinning and provides an ideal thread form. A KM coat (for steel products) option is also available for enhanced corrosion resistance.
●Head shape is pan (truss) type.
●Material is corrosion-resistant stainless steel SUSXM7.
●Applications include: wood-to-wood fastening, ALC, verdigris, floor framing, concrete formwork panels, siding substrate, particle board installation, siding substrate, roof tile batten fixing, etc.
