Stainless Steel Countersunk Sheet to Heavy Section

For fixing sheet to hot rolled purlins (4.0mm – 12.5mm steel).


 

This standard anti-corrosion coating ensures our fasteners can withstand over 500 hours in a salt spray test. It is a specialist epoxy zinc and aluminium compound which produces a multi layered, scratch resistant coating. Countersunk heads lie flush with the surface of the substrate. They generally have a torx drive. Countersunk heads lie flush with the surface of the substrate. They generally have a torx drive.

Heavy section screws fasten sheet metal to hot rolled purlins (4.0mm – 12.5mm steel).

  • Stainless steel provides excellent corrosion-resistance which increases the life-span of the fixing.
  • Countersunk heads lie flush with the profile, and require T-25 bits.
  • The fine thread provides many points of engagement with the purlin, maximising pull-out values.
  • The no. 5 drill point is designed to ensure a clean cut through up to 12.5mm steel, without burn-out.

For maximum fastener performance, we recommend using a tek screw driver which does not exceed 2500RPM.
