Product Details

Widely used in tunnels, mines, railroads, highways, dams, the main body of the reinforcement of overrun support, pit support, slope support and other geological medium good perimeter rock for system support.

Nut performance level labeling has two parts of the digital composition, respectively, indicating the nut material nominal tensile strength value and flexural strength ratio value. For example, the performance level 4.6 level of the nut, its meaning is: 1. nut material nominal tensile strength of 400MP * level; 2. nut material spread strength ratio value of 0.6; 3. nut material nominal service strength of 400X0.6 = 240HP * level

Specification and Parameters

The specifications correspond to the anchor specifications, commonly used specifications are M18, M20, M22, M24.

Product Description

Anchor rod nut is a supporting part of anchor rod, used to match the support of anchor rod. Mining Anchor Nut,Coal Mine Nut,Mining Nut Specification,Mining Nut Anti Loosening Nut is composed of two parts, each part of the anti loosening 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 tightly bitten together as a whole, when vibration occurs, the DISC-LOCK anti loosening nut protruding part of the staggered with each other, resulting in the lifting of the tension to achieve the perfect anti loosening effect. Achieve perfect anti-loosening effect.Coal mine anchor nuts include: torsion nuts, torsion nuts with washers, hexagonal nuts with washers, quadrilateral nuts with washers, mushroom head nuts, thickened nuts for coal mine anchors, and anti-loosening nuts for coal mine anchors. Electroplating of nuts means that the part of the nut to be plated is immersed in a specific aqueous solution, which contains some deposited metal compounds, so that after passing the current through the aqueous solution, the metal substances within the solution precipitate out and adhere to the immersed part of the nut. Plating of nuts generally includes galvanizing, copper, nickel, chromium, copper-nickel alloys, and so on.
