Shop beam clamps for attaching threaded rod, pipe hangers, and support hardware to structural steel beams. Beam clamps are commonly used in mechanical, plumbing, fire protection, and industrial piping installations where a hanger assembly needs to be secured to a beam without drilling, welding, or modifying the structure.
PipingNow offers Empire Industries beam clamps in small mouth and wide mouth styles for 3/8 in and 1/2 in threaded rod. Available options include plain finish, electro-galvanized, 304 stainless steel, and 316 stainless steel beam clamps.
What Are Beam Clamps Used For?
Beam clamps provide a connection point between a structural beam and a pipe hanger assembly. Instead of fastening directly through the beam, the clamp grips the beam flange and allows threaded rod or other support hardware to be attached below it. This makes beam clamps useful for suspending pipe, conduit, tubing, equipment supports, and other overhead hanger systems.
Because beam clamps are installed directly onto the beam flange, they are often used when drilling is not allowed, when field welding is not practical, or when an adjustable support point is needed during installation.
Small Mouth vs. Wide Mouth Beam Clamps
This collection includes both small mouth beam clamps and wide mouth beam clamps. Small mouth beam clamps are used for standard beam flange applications where the flange thickness fits within the clamp opening. Wide mouth beam clamps provide a larger opening for beam flanges that require additional clearance.
When selecting a beam clamp, confirm the beam flange thickness, threaded rod size, material or finish requirement, and the support load requirements for the application. Matching the clamp style to the beam and hanger assembly helps ensure a cleaner and more secure installation.
Beam Clamp Materials and Finishes
Beam clamps are available in several material and finish options depending on the environment and project requirements. Plain finish beam clamps are commonly used in general-purpose applications. Electro-galvanized beam clamps provide added surface protection for many standard support installations.
For applications where corrosion resistance is more important, stainless steel beam clamps may be the better choice. 304 stainless steel is a strong general-purpose stainless option, while 316 stainless steel offers added corrosion resistance for harsher environments, washdown areas, coastal locations, and industrial applications where exposure may be a concern.
Threaded Rod Sizes
PipingNow carries beam clamps for 3/8 in and 1/2 in threaded rod. Use the size filters on this page to narrow the collection to the rod size needed for your hanger assembly. If the beam clamp will be used with pipe hangers, clevis hangers, or other support components, make sure the rod size matches the rest of the hanger system.

How to Choose the Right Beam Clamp
Start by identifying the beam flange size and the threaded rod size used in the support assembly. Choose a small mouth or wide mouth beam clamp based on the flange clearance needed. Then select the material or finish based on the environment. For standard indoor use, plain or galvanized beam clamps may be suitable. For more demanding applications, stainless steel beam clamps can provide improved corrosion resistance.
If the beam clamp is part of a larger pipe support system, also review the connected pipe hanger, threaded rod, and support hardware to make sure the full assembly is compatible.

Beam Clamp FAQs
What is a beam clamp?
A beam clamp is a pipe support component that attaches to a structural beam flange and creates a connection point for threaded rod, hangers, or other support hardware.
What is the difference between small mouth and wide mouth beam clamps?
Small mouth beam clamps are used for standard beam flange applications. Wide mouth beam clamps have a larger opening and are used when additional flange clearance is needed.
What threaded rod sizes are available?
This collection includes beam clamps for 3/8 in and 1/2 in threaded rod.
Are stainless steel beam clamps available?
Yes. This collection includes 304 stainless steel and 316 stainless steel beam clamp options, along with plain and galvanized options.
