Professional Applications & Engineering Value
This heavy-duty toggle eyebolt solves critical anchoring challenges in construction and maintenance applications where traditional fasteners fail. The zinc-plated steel construction combined with the 2 1/8" wing span toggle mechanism creates exceptional pull-out resistance in drywall and plaster substrates, preventing costly wall damage and fixture failures. The partially threaded design with UNC 1/4"-20 coarse threading ensures quick installation while maintaining structural integrity. Engineering professionals value the integrated eye diameter of 7/32" for secure attachment points in HVAC, electrical, and plumbing installations, making it ideal for commercial building applications requiring reliable overhead support.
Specification Summary & Compliance
Manufactured to precise Class 2A screw thread fit and Class 2B toggle thread fit tolerances with UNC coarse threading standards. Complies with ASME B18.6.3 specifications for dimensional accuracy and mechanical performance. Meets RoHS 3 (2015/863/EU) environmental compliance requirements. Designed for use with standard 5/8" diameter holes (0.625") using appropriate drill bits. The Rockwell B68 hardness ensures consistent performance under load conditions.
