With the Spax Spax-RA frame screw, you can mount window and door frames quickly and stress-free without using wall plugs. This 7.5 x 150 mm steel screw drives directly into pre-drilled masonry or concrete, allowing precise stand-off installation without distorting the frame. Its small cylindrical head sits neatly and unobtrusively within the frame profile. The t-star plus T30 recess ensures optimal torque transmission and prevents cam-out while driving. In addition, the durable wirox coating delivers enhanced corrosion protection, providing a solid and long-lasting anchor for renovation and new-build projects.
