Nvent M58S Beam Clamp 5/16 to 1/2 Inch Flange

Product Description

The NVENT M58S is a beam clamp designed to attach threaded rod, wire, or support hardware directly to structural steel beam flanges without drilling or welding. It accommodates flange widths from 5/16 inch to 1/2 inch, making it suited for light structural steel commonly found in commercial and industrial construction. Electricians, plumbers, and mechanical contractors use this clamp to hang conduit, pipe, ductwork, cable tray, and other overhead systems from exposed steel framing. The clamp provides a fast, code-compliant attachment point that eliminates the need for powder-actuated fasteners or field-drilled connections.

The M58S is a common component in electrical, plumbing, and HVAC rough-in work wherever systems must be suspended from structural steel. It is appropriate for commercial buildings, industrial facilities, and institutional construction where beam flanges fall within the supported size range. Licensed electricians installing conduit runs and mechanical contractors hanging pipe hangers or strut channel will encounter this clamp as a standard suspension component.

Key Features

• Accepts beam flange widths from 5/16 inch to 1/2 inch
• Eliminates drilling or welding to structural steel
• Provides a threaded attachment point for rod, wire, or hanger hardware
• Compact profile fits tight overhead spaces
• Suitable for use across electrical, plumbing, and mechanical trades

Compatibility

Designed as an OEM-style beam clamp for use with standard threaded rod and support hardware on structural steel beam flanges measuring 5/16 inch to 1/2 inch in width.

Installation Notes

Installation should be performed by a licensed electrician or qualified mechanical contractor in accordance with applicable local codes and NEC or IPC requirements. Shut down any energized systems in the work area before positioning overhead hardware. Verify the beam flange width falls within the supported range before tightening the clamp. Do not exceed the rated load capacity of the clamp or the suspended hanger assembly.
