Product Detail
Structure: This product is an integrated single-piece hex head bolt. Matching flat washers, spring lock washers and nuts of corresponding materials can be equipped according to on-site construction requirements.
Application: Grade 4.8 integrated hex bolts are used for connecting secondary enclosure and light support components such as steel roof purlins, wall beams, bracing rods, knee braces and guardrails of steel structures. They are only applicable to secondary stress joints with light self-weight and normal wind loads. This specification shall not be adopted for critical load-bearing parts including main load-bearing rigid frames and crane beams. Materials shall be selected strictly according to load grade to ensure the overall structural safety.
