6.3 x 85mm Heavy Duty TEK X Self-Drilling Screws (SuperTEK) (X100)

  • Fixabolt SKU: FB-TSHW6.3-85-X
  • Range: Evolution SuperTEK X (Q10)
  • Head Style: Hex head, 5/16" (8mm across flats)
  • Drill Point: SuperTEK X heavy-section drill point
  • Thread: 14 TPI intermediate V-fluted thread
  • Thread Length: Fully threaded
  • Material: AISI C1022 carbon steel
  • Coating: 1000hr-rated EvoShield
  • Box Quantity: 100 screws

These 6.3 x 85mm SuperTEK X heavy-duty self-drilling screws are designed for steel-to-steel fastening in heavy-gauge structural sections. They use Evolution’s specialist SuperTEK X drilling point for applications requiring a heavy-section self-drilling fixing, including brackets, secondary framing and steelwork components.

Unlike the finer 24 TPI thread on the SuperTEK 7 and 8 ranges, SuperTEK X uses a 14 TPI intermediate V-fluted thread. The 5/16" (8mm across flats) hex head is intended for a suitable non-impact socket drive, and the AISI C1022 carbon steel has a 1000hr-rated EvoShield coating.

The 85mm version is fully threaded according to Evolution’s product guide. Its intermediate-pitch thread is intended to provide positive engagement in the steel sections being joined. The length is particularly relevant where the fixing must pass through one or more components before engaging the supporting steel.

This is an unwashered fixing for connections where an integral weather seal is not required. If your installation needs sealing at the fixing point, browse our bonded sealing washers. The correct fastener and drilling capacity should be checked against the application and Evolution technical guidance.
