The channel-section steel nut that uses on the existing market is mostly two kinds: one is a crossed half-tooth type; one is of a transverse tooth type;

a channel steel nut (shown in figure 6) is of a cross half-tooth type, and is structurally characterized in that teeth are deep and are sharp. More of the teeth-free steel channel are matched, and the steel channel occlusion edge is yielded to generate tooth impressions by applying enough torque, so that the crossed half teeth are matched with the tooth impressions of the steel channel to form a meshing state. The disadvantage of the crossed half-tooth channel nuts is also evident, in order to make it easier for the channel bite to yield producing tooth marks, it is first of all necessary to reach a high torque (typically 60 n.m-80 n.m), and such teeth must be relatively sharp and the structure must be strong; therefore, the required torque is high, and the small meshing area becomes a negative factor.

The second type is a transverse tooth type channel steel nut (as shown in fig. 7) which is mostly matched with a channel steel with teeth, the biggest defect of the channel steel nut is that the edges are not sunk, because meat is accumulated due to stamping in the manufacturing process, when the meat is clamped among the teeth of the channel steel, the meat is propped against the inclined edge of a small isosceles trapezoid of the teeth of the channel steel, so that a plurality of teeth beside the meat cannot be tightly or hollowly meshed with the teeth of the channel steel, the teeth are not well meshed, and the anti-sliding performance is reduced; in addition, the depth of the teeth of the channel steel nut is relatively shallow, so that the occlusion depth is insufficient, and the optimal anti-sliding effect cannot be achieved.

Therefore, in order to solve the problem that the channel steel nut is poor in anti-sliding capability, a channel steel nut with anti-sliding capability is provided.
