High Tensile Full Threaded Rod Galvanized Roofing Bolts With Nut and Washer Carbon Steel 4.8 Material

1.Product Description

Roofing Bolts components in the concrete foundation installation, the bolt was J-shaped, L-shaped end buried in concrete use.
The tensile strength of the anchor bolt is the tensile strength of the round steel itself, the size is equal to the cross-sectional area multiplied by the allowable stress value (Q235B: 140MPa, 16Mn or Q345: 170MPA) is the design of the allowable tensile capacity.
Anchor bolts generally use Q235 steel, that is round. Screw steel (Q345) strength, so the nut does not have a round wire easily round. For an optical round stud, the depth is typically 25 times its diameter, and then a 90 degree hook about 120mm long. If the bolt diameter is too large (such as 45mm) depth is too deep, you can solder the side plate in the bolt, that is to do a big head on it (but there is a certain requirement). Burial depth and the hook is to ensure that the friction between the bolt and the foundation, and will not pull out of the bolt damage occurred.
Load testing with Eye bolt by 2.5 times the working load are 20,000 times fatigue test at 1.5 times the working load. Screw rings to meet or exceed ASME B30.26 standards. Screw rings made of high alloy steel by reference to Germany RUD WBG type production, the products are exported to Europe and America, and by local-level G80 standard test. Better material than the existing domestic screw rings Rally higher offers tensile testing reports. Screw rings shall professionals operation, see the instructions for use and, when connected to the spreader should be kept with the spreader rings rotatable joints, professionals should conduct regular safety inspection. Maximum working load of up to 30T, and can be customized inch thread.
