Tek 8 Screws

Our TEK 8 screws are self-drilling screws designed for fastening into thick steel sections where conventional Tek screws lack the required drilling capacity. Featuring specialist spiral drill points, they can drill and form threads in heavy-gauge steel in a single operation, removing the need for separate pilot holes within their rated drilling range.

Their hardened TEK 8 drill points are designed to penetrate thick steel in steel-to-steel connections, while the threaded shank provides secure engagement. Their 8mm hex heads allow installation using a suitable socket driver.

TEK 8 self-drilling screws are commonly used for:

  • Fixing brackets and components to steel beams and columns
  • Heavy-gauge steel framing and assemblies
  • Industrial fabrication and steel construction
  • Securing secondary steelwork to supporting structures
  • General heavy-duty metal-to-metal fastening

TEK 8 Drill Points and Specifications

TEK 8 screws feature an extended spiral drill point designed for penetrating thick steel sections.

High-performance ranges, including Evolution SuperTEK 8, offer drilling capacities of up to 22mm in steel, making them suitable for applications beyond the capabilities of standard TEK 3 and TEK 5 screws.

These screws typically use hardened carbon steel for drilling performance, with protective coatings helping to resist corrosion. Exact drilling capacities, thread designs and finishes depend on the manufacturer.

Fixabolt supplies heavy duty self-drilling screws for steel fabricators, engineers, builders and industrial installers throughout the UK. Browse available pack quantities or contact us through live chat for product advice.
