Heavy-Duty Zinc-Plated Steel Pipe U-Bolts – Round Bend Pipe & Conduit Support Clamps with Hex Nuts & Washers (Multi-Size Selection)
Heavy-Duty Zinc-Plated Steel Pipe U-Bolts – Round Bend Pipe & Conduit Support Clamps with Hex Nuts & Washers (Multi-Size Selection)
Firmly clamp and anchor rigid piping systems, steel conduits, PVC drainage pipes, and structural round tubing onto steel beams, mounting plates, and Unistrut channels with our Heavy-Duty Zinc-Plated Steel Pipe U-Bolts. Manufactured from high-tensile carbon steel formed into a precision round bend, each U-bolt comes pre-assembled as a complete fastening kit including two matching metric hex nuts and two heavy-duty flat washers.
Designed to securely wrap around standard Nominal Bore (NB) steel pipes, PPR lines, CPVC, UPVC, and EMT/RMC electrical conduits, these U-bolts prevent pipe displacement, lateral movement, and axial slippage under pressure surges and structural vibration. The heavy electro-zinc passivated coating guarantees exceptional protection against atmospheric rust, humidity, and chemical corrosion in plumbing, HVAC, electrical, and civil infrastructure applications.
Key Features
-
Complete Fastener Kit: Every U-bolt includes 2 precision-threaded hex nuts and 2 flat washers for instant, out-of-the-box field installation.
-
Precision Round Bend Profile: Engineered to match standard Nominal Pipe Sizes (NPS / DN) for uniform 360° clamping force without crushing or denting pipe walls.
-
Corrosion-Resistant Zinc Coating: Bright electro-galvanized finish shields carbon steel against oxidation, moisture, and indoor/outdoor environmental exposure.
-
High Load Capacity: Full-strength rolled metric threads provide deep thread engagement and high pull-out resistance under heavy structural loads.
-
Universal Mounting Compatibility: Mounts seamlessly onto steel channel struts, angle irons, I-beams, masonry wall brackets, and machinery frames.
