5.5 x 75mm A2 Bi-Metal Tek Screws - Box of 100

  • Head Style: Hex head
  • Hex Head Size: 5/16"

These 5.5 x 75mm A2 bi-metal Tek screws combine an A2 stainless steel body and head with a hardened carbon steel drill point. This construction provides the corrosion resistance associated with stainless steel while giving the point the hardness needed to drill consistently through light-gauge steel.

Compared with conventional all-stainless DIN 7504K self-drilling screws, the bi-metal design offers trades a more dependable drilling action in suitable steel thicknesses while retaining an A2 stainless steel body above the fixing surface. They are intended for fastening aluminium sheet, panels and other components to light-gauge mild steel, and may also suit similar sheet-to-steel applications where the stated drilling capacity is appropriate.

The 16mm bonded washer helps spread the clamping load and provides a sealing interface around the fixing point, making this version useful for sheet and panel applications where weather sealing is required.

The coarse TEK 3 thread helps develop a secure fixing in thin steel sections, while the hex drive provides positive engagement for controlled installation.
