• Durable steel construction ensuring structural integrity for heavy-duty hanging applications up to 0.038" material thickness

Professional Applications & Engineering Value

This zinc yellow-chromate plated steel hanger bolt addresses critical challenges in industrial hanging applications where corrosion resistance and structural reliability are paramount. The eye head design with 3/16" diameter provides a secure attachment point for cables, chains, or hooks while the thread forming BSD tapping screw technology eliminates the need for separate tapping operations in steel substrates. The partial threading configuration concentrates the holding power where needed most, while the integrated drilling tip streamlines installation in steel applications up to 0.038" thickness. Engineered for heavy-duty fastening solutions, this hanger bolt combines the durability of steel construction with advanced surface treatment for long-term performance in challenging environments where vibration, load stress, and environmental exposure are constant concerns.

Specification Summary & Compliance

This 1/4"-14 hanger bolt features precision right-hand threading with approximately 14 threads per inch and complies with standard BSD tapping screw specifications. The partial threading extends 1½" from the tip with thread forming design for superior holding power in steel applications. Manufacturing follows industry standards for dimensional accuracy, with the zinc yellow-chromate plating providing RoHS and REACH compliant corrosion protection. The product is engineered for use in steel materials with maximum drilling thickness of 0.038", ensuring reliable performance in industrial fastening applications.
