They have a torque limit. Apply too much torque, and the base material will just get chewed up by the threads of the self tapper, widening the hole, leaving nothing for the thread to bite on. A drill can be used with a torque limiting clutch, but personally I prefer to use a screwdriver so I can feel what I''m doing before I screw it up. But I''d never trust self tapping screws to hold solar

Customer ServiceProper torque is essential for preventing failures and maximizing the lifespan of solar panels. Torque tubes provide structural support, minimize stress on panels, increase stability, and reduce wind loads. By implementing torque tube
Customer ServiceI''ve doing a ground-mount of a 4x4 array of 39x65" panels in landscape orientation. I''ll use two pairs of 14ft IronRidge XR1000 rails (supported by wooden girders at each end), at a 26degree angle. The panels will be attached to the rails using IronRidge''s little "UFO" clamps; each rail has a clamp at each
Customer ServiceIn the case of torque measured from any contract pile being less than the minimum control torque obtained above, the pile is recorded as suspected pile and will be verified by static pile load test. In case rocky ground is found on some part of the project, pre-holes will have to be made. This means the use of an auger will come into play
Customer ServiceProper torque is essential for preventing failures and maximizing the lifespan of solar panels. Torque tubes provide structural support, minimize stress on panels, increase stability, and reduce wind loads. By implementing torque tube solutions, businesses can ensure the long-term performance and cost-effectiveness of their solar panel systems
Customer ServiceWith the details of my install location, it''s going to require a bit more than a 3.5'' reach to get to the mid-clamp. How do people normally tackle this? I''m aware that one can buy extended reach socket wrenches with 2'' long handles, and maybe longer handles exist. But I''d prefer to use my torque wrench during the install.
Customer ServiceIn the case of ground screws, they are typically applied to more dense soils and solids with rock intermixed. A ground screw should not be used in solid rock. Ground screws in hard soils have pullout values of 1500 to 5000 pounds at a depth of 5 ft., however this estimate is entirely based upon the soil density. The use of ground screws in
