Product description
JG Impact all purpose masonry screws, 7.5 x 122mm, box of 100. A plug free, self tapping screw that drives straight into concrete, brick and block with no wall plug.
The high low twin thread grips hard for a strong hold and lets you fix close to an edge without cracking the substrate. Fire resistance is better than a nylon plug, so it suits frame and batten fixing. Each box comes with a T30 Torx bit and cover caps.
