Premium Carbon Steel and Stainless Steel Strut Channel Accessories Supplier

The electrician’s on-site, running conduit through a tight mechancial room, and they need a strut channel nut that seats cleanly in the 41mm slot without jamming—our BIM3531 hex head fits that, with a 5mm to 7mm thickness range depending on the load, and we ship form the China warehouse in about 20 days or so.

We’ve run these through a few thousand cycles in a vibration test rig for a client in the oil and gas sector—the medium carbon steel with HDG coating held up better than the standard zinc-plated stuff for outdoor exposure, though the stainless variant is what you’d want if chloride corrosion is a concern.

It basically uses a standdard hex head profile, so you can torque it with a common socket wrench, and the surface treatment options—galvanized sheet, HDG, or powder coated—mean you pick your corrosion resistance level base on the environment, not the fastener’s strength.

Most buyers go with the 6mm thickness for general framing work, but we’ve seen some strucutral guys spec the 7mm for seismic bracing where the load rating needs that extra margin—the DIN and ANSI compliance is baked into thread pitch and dimensional tolerances.

One thing that catches people is the HS code (8604299000) doesn’t match typical fastener codes—it’s actually for railway track fixtures, so customs might flag it if you’re importing for general construction, but we usually have teh COA ready to clarify the end use.

5mm is fine for light-duty cable tray supports, but don’t use it for overhead lifting or anything —the hex head’s not designed for that, and the stainless version’s tensile strength is roughly 20% lower than the carbon steel equivalent anyway.
