Product Details:
Coal mine anchor nuts include: torque nuts, torque nuts with pads, hexagonal nuts with pads, quadrilateral nuts with pads, mushroom head nuts, thickened nuts for coal mine anchors, anti-loosening nuts for coal mine anchors. Mining anchor nut is composed of two parts, each part of the nut has staggered cams, due to the internal wedge design slope angle is greater than the angle of the bolt's nut, this combination will be tight bite into a whole, when there is a vibration occurs, DISC-LOCK anti-loosening nut raised part of each other staggered, resulting in the lifting of the tension, so as to achieve a perfect anti-loosening effect. Widely used in tunnels, mines, railroads, highways, dams, the main body of the reinforcement of the over-support, pit support, slope support, etc. Geological medium good rock surroundings for system support.
Nut performance level labeling has two parts of the digital composition, respectively, indicating the nut material's nominal tensile strength value and flexural strength ratio value. For example, the performance level 4.6 level of the nut, its meaning is: 1, the nut material nominal tensile strength of 400MP * level: 2, the nut material of the spread of the strength ratio value of 0.6: 3, the nut material of the nominal service strength of 400X0.6 = 240HP * level. Anchor nut is a supporting part of anchor, used to cooperate with the support of anchor. Mining anchor nut is composed of two parts, each part of the nut has staggered cams, due to the internal wedge design slope angle is greater than the angle of the bolt's nut, this combination will be tight bite into a whole, when there is a vibration occurs, DISC-LOCK anti-loosening nut raised part of the mutual staggered, resulting in the lifting of the tension, so as to achieve the perfect anti-loosening effect.
