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

High Tensile, Offer High Holding Power, Corrosion Resistance
Eye bolt widely used in ports, power, steel, shipbuilding,
petrochemical, mining, railways, construction, metallurgy,
automobile manufacturing, plastics machinery, industrial control,
highways, large transport, pipelines and auxiliary set, slope
tunnels, wells control protection, salvage, ocean engineering,
airport construction, bridges, aviation, aerospace, and other
important venues and infrastructure construction industry,
machinery and equipment.
1. eye bolts should be 20 or 25 steel (GB699) Manufacturing.
2. The eye bolts must be approved by the whole forging. Forgings
should be normalized, and remove oxide. Grain size of the finished
product should not be lower than level 5 (GB6394), forgings should
not have been burnt, crack defects.
