Hex Head Self Drilling Tek Bolts (0)

Coloured hex head self drilling tek bolts for cladding and facade work - powder coated in any RAL colour, driven with a nut runner for fast, high-torque fixing into structural steel without pre-drilling.

The hex head takes a socket or nut-runner drive, delivering the torque needed to seat cladding fixings quickly and consistently across large facade areas. The self-drilling point penetrates structural steel and thicker sections in one action, making these the workhorse fixing for cladding rails, sheeting, and panel-to-steel-frame fixing where installation speed across a big elevation is critical. Powder coated to the cladding colour, the head stays consistent with the panel even on exposed fixing lines. For panel-face fixings that need a lower profile behind closed joints, see pancake head self drilling screws.

Available in BZP steel, powder coated in-house to any of our 40+ stocked RAL colours, with the full RAL Classic range available to order. Standard lead time 3–5 working days. Browse the full cladding & facade range.
