This box contains 50 A4 stainless steel bi-metal masonry screws in 8.0 x 350mm size for fixing timber battens, trunking, track and general components into concrete, masonry and timber.

The A4 stainless steel body gives this range exceptional corrosion resistance for external and exposed applications, while the hardened carbon steel point and lead thread help the screw tap consistently into masonry substrates during installation.

The aggressive threadform is designed to provide strong holding power without expansion pressure, making these screws useful where fixings need to be positioned closer to the edge of the substrate than traditional expansion anchors would allow.
