Attach hanger rods directly to structural steel — no drilling required. Beam clamps bolt onto beam flanges to provide a hanger rod attachment point without welding or drilling. The standard solution for anchoring mechanical system hanger rods to structural steel in commercial and industrial buildings. Clamp-on design — no welding or drilling to the structural steel Accepts standard threaded hanger rod (3/8" or 1/2") Supports pipe hanger, strut, and equipment suspension loads Pre-Galvanized construction MSS SP-58 / SP-69 compliant ✔ In Stock — Ships Same Day or Next Business Day✔ Used by contractors and professionals✔ Designed for reliable jobsite performanceOverviewC-Clamp w/ Locknut Plain Finish Domestic 1/2" is a c-clamp beam attachment for connecting threaded hanger rods to structural steel beams in commercial and industrial mechanical systems. Beam clamps attach to the beam flange by clamping — no welding or drilling to the structure. Faster to install and removable, with load ratings suitable for most commercial pipe and equipment support applications. Once installed, standard threaded hanger rods connect to the attachment to support pipe hangers, strut channel, or equipment below.Common Uses Anchoring hanger rods to structural steel beams Supporting pipe hanger systems from steel framing Suspending strut channel from beam flanges Mechanical, electrical, and plumbing system support Commercial and industrial building construction Key Features Clamp-on — no welding or drilling to structural steel Threaded rod connection (3/8" or 1/2" rod) Pre-Galvanized construction MSS SP-58 compliant load rating Specifications Type C-Clamp Beam Attachment Finish Pre-Galvanized Installation Clamp-On (No Welding) Rod Connection Threaded Rod (3/8" or 1/2") Standard MSS SP-58 / SP-69 Frequently Asked QuestionsWhat is a beam attachment used for?Beam attachments provide an anchor point on structural steel beams for connecting hanger rods that support pipes, strut channel, and mechanical equipment below.Welded vs. clamp-on beam attachments — which do I use?Welded attachments are permanently fixed and carry higher loads — required for heavy systems and seismic applications. Clamp-on attachments install faster, require no welding, and handle most standard commercial pipe support loads.What rod size do beam attachments accept?Most standard beam attachments accept 3/8" or 1/2" threaded hanger rod. Heavier-duty versions accept larger rod sizes.Do beam clamps damage the structural steel?Clamp-on beam attachments grip the flange without welding or drilling — they do not damage or modify the structural steel and are removable if needed.Why Contractors Choose This Product Clamp-on design installs in minutes without welding or drilling — faster and cleaner than weld-on on most commercial projects Standard threaded rod connection is compatible with all standard pipe hangers and strut fittings MSS SP-58 compliant — meets the pipe support engineering standards required on commercial and institutional jobs PVFPro stocks both weld-on and clamp-on styles across standard load ratings Buying in volume?
