Thimble Eye Bolts are forged steel fasteners used in overhead power line and communication network infrastructure for guying and deadending applications to secure cables, wires, and strands to utility poles, crossarms, or anchors. Manufactured in straight and 45-degree bent styles, they provide versatility for different pole line hardware installations.
The broad radius eye serves as an attachment point for deadend or guy messenger wire, guy strand, or formed wire grips, eliminating the need for thimbles, shackles, links, and guy hooks. This design streamlines assembly and reduces hardware requirements. The threaded shank features a cone point with a standard square nut (hexagon nuts available as alternative) and cut threads for secure fastening in wood poles.
Corrosion resistance is achieved through hot dip galvanized finishes, Thermal Diffusion Galvanizing (TDG) per ASTM A 1059, or TransArmour coatings. TDG provides superior corrosion protection and extended service life compared to conventional hot dip galvanizing. Minimum tensile strengths are 13,550 pounds for 5/8-inch diameter and 20,050 pounds for 3/4-inch diameter bolts.
Available in 5/8-inch and 3/4-inch diameters with overall lengths from 8 to 36 inches and thread lengths typically 4 to 6 inches, the bolts comply with Rural Utilities Service (RUS) Listing, ASTM A 1059, IEEE Standard C135.2, and Bell Specification CAO 7082 for anchor rod applications.
