Stainless Steel Hex Head Sheet to Medium Section 

For fixing sheet to cold rolled purlins (1.5mm – 6.0mm steel).


      

Part Number Length (MM) Diameter (MM) Drill Point
25.3SS 25 5.5 No. 3
38.3SS 38 5.5 No. 3

Medium section screws fasten sheet metal to cold rolled purlins (1.5mm – 6.0mm steel).

  • Stainless steel provides excellent corrosion-resistance which increases the life-span of the fixing.
  • Hex heads are standard across the industry, and require a 5/16″ socket, which we also supply.
  • The coarse thread provides excellent engagement with the purlin, maximising pull-out values.
  • The no. 3 drill point is designed to maximise accuracy whilst ensuring a clean cut through up to 6.0mm steel, without burn-out.

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