Cable tray bolts and nuts

Cable tray installations typically use zinc-plated bolts with serrated or hex flange nuts for secure, rapid, and corrosion-resistant fastening.Types and FeaturesCable tray bolts are designed for quick and secure assembly of cable trays and trunking systems. Common features include:Thread Size: Most standard bolts are M6 (6mm diameter), though M7 and other sizes are also available depending on tray specifications .Nut Type: Serrated flange nuts or hex flange nuts are commonly used. The serrated flange grips the tray material, preventing loosening without the need for additional washers .Washer Integration: Some bolts come with a fixed washer attached to the flange nut, which prevents the nut from falling off during installation and simplifies assembly .Head Type: Bolts often feature cross-slot or No. 2 Pozi drive combo heads, allowing fast installation with standard screwdrivers or socket drivers .Finish: Zinc plating is standard to provide corrosion resistance, especially in industrial or outdoor environments .Installation AdvantagesRapid Assembly: The combination of flange nuts and integrated washers reduces the need for fiddly components, speeding up installation.Secure Fixing: Serrated flanges lock the nut in place, minimizing the risk of loosening due to vibration or load.Compatibility: These bolts are suitable for a wide range of cable tray materials, including steel and aluminum trays.Packaging and AvailabilityBolts are often sold in boxes of 100 or more, making them convenient for large installations .Sizes and finishes can vary, so it is important to select bolts compatible with the specific cable tray system being used. Using the correct nuts and bolts for cable trays ensures a safe, durable, and efficient installation, reducing maintenance needs and improving overall system reliability.
