The Ziegler 5/8-11 x 5-1/2" carriage bolt set is a complete heavy‑duty fastening kit featuring 26 bolts with matching nuts and washers for structural and industrial work. Each bolt has a smooth domed head and a square neck that prevents rotation during tightening, allowing secure installation with a nut. Specifications: size 5/8"-11 (UNC coarse thread); length 5-1/2 inches; material steel; head type domed carriage bolt with square neck. The non-rotating square neck locks into the material during tightening to deliver a flush, tamper-resistant finish in demanding environments.

This kit provides a high-strength, secure hold for heavy-duty connections where you need reliable performance and a neat, unobtrusive appearance.
