Product Description
Drop Forged Bolt Eyelet HDG | IEEE C135.80 Guying Eyelet for 5/8" & 3/4" Bolts
The Yokelink Drop Forged Bolt Eyelet (also known as a Thimble Eyelet) is an incredibly versatile and cost-effective solution for overhead poleline construction. Instead of stocking expensive, dedicated eye bolts in varying lengths, linemen can simply slip this eyelet over the threaded end of any standard utility machine bolt to create a secure, high-tension termination point for guy wires.
Engineered for Maximum Strand Protection:
Available in both Straight and 45-Degree Angle designs, these eyelets feature a deeply grooved, thimble-shaped contour. This critical design cradles the steel guy strand, maintaining its natural bending radius to prevent kinking, flattening, and stress concentration under massive load.
Drop Forged for Unyielding Strength:
Manufactured from high-yield carbon steel through a drop-forging process, Yokelink Bolt Eyelets easily meet the rigorous strength requirements of ANSI/IEEE C135.80. Each piece is fully Hot Dip Galvanized to ASTM A153 to ensure supreme corrosion resistance in the harshest outdoor utility environments.
Key Technical Features of Bolt Eyelet
Cost-Effective: Converts any standard machine bolt into a guying attachment.
Design: Grooved thimble contour protects guy wire from sharp bends.
Styles: Available in Straight or 45° Angled configurations for different guying drops.
Manufacturing: Drop-forged carbon steel for ultimate structural integrity.
Finish: Heavy-duty Hot Dip Galvanized (HDG) per ASTM A153.
Production Process of Bolt Eyelet
The production of bolt eyelet starts with selecting high‑quality carbon steel or alloy steel bar, which is cut into fixed‑length blanks and then hot forged to form an integrated eye head and shank. After trimming and shaping, the external thread on the shank is rolled with high precision to ensure good fit and strength. The semi‑finished product is then heat treated through quenching and tempering to improve tensile strength and toughness. Finally, it is hot‑dip galvanized for corrosion resistance, followed by dimensional inspection, thread testing, hardness check and visual inspection before packaging.

We don't just reference standards; we also verify them in practice: each batch of products undergoes destructive tensile testing in our internal laboratory to ensure load performance exceeds the minimum requirements of IEEE C135.2 or CSA C83 specification; we use optical comparators to ensure the geometric accuracy of chamfered tips and rolled threads, enabling convenient on-site installation; at the same time, we conduct comprehensive testing on Rockwell hardness, coating thickness, and other parameters, and each shipment is accompanied by the original manufacturer's material specifications (MTRs) and quality inspection reports, with all data traceable back to the raw material furnace number.
Application of Bolt Eyelet
Bolt eyelet is a commonly used connecting component in overhead power lines, communication towers, and pole and tower guying systems. It is mainly used to connect guy wires, stay rods, insulators and other tension fittings, providing a firm hinged connection for bearing pulling force. With high structural strength and reliable mechanical performance, it can maintain stable connection under long-term outdoor load. After hot-dip galvanizing, it has good corrosion resistance and long service life. It is widely used in transmission line construction, substation equipment and various engineering guying and fixing scenarios.
Yokelink Product Quality Inspection Report
We provide comprehensive inspection services for machine bolts, including SGS test bolts and formal Production Part Inspect Report (PPIR). The SGS tests verify the bolts’ compliance with international standards like ASTM A307 and IEEE C135.80, covering mechanical properties and corrosion resistance. The PPIR details all inspection items, ensuring each machine bolt meets dimensional, performance and quality requirements, providing reliable quality assurance for overhead line and industrial applications.

Frequently Asked Questions (FAQ)
Q1: What is the advantage of using a Bolt Eyelet instead of a Thimble Eye Bolt?
A: Inventory flexibility and cost savings. Utility poles vary greatly in diameter, requiring bolts of many different lengths. Instead of buying and storing expensive Thimble Eye Bolts in 10", 12", 14", and 16" lengths, a contractor can simply stock standard Machine Bolts (which are cheaper and used everywhere) and slide a Bolt Eyelet onto the end to create a guy point whenever needed.
Q2: What is the difference between a Bolt Eyelet and an Eye Nut?
A: A Thimble Eye Nut has internal threads and screws directly onto the threaded end of a bolt to secure it. A Bolt Eyelet has an unthreaded slip-hole. It slides over the bolt's threads and sits against the wood pole or washer. You must then thread a separate standard square or hex nut onto the bolt behind the eyelet to lock it securely in place.
Q3: When should I use a Straight Eyelet vs. an Angle Eyelet?
A: A Straight Eyelet is typically used for head-guying or when the guy wire is running horizontally (parallel) to the bolt. A 45-Degree Angle Eyelet is the most common for down-guying, as the angle naturally points the eye downward toward the earth anchor, preventing the guy wire from bending sharply against the hardware.
Q4: Will the galvanized coating inside the eyelet hole prevent it from fitting over the bolt?
A: No. Yokelink engineers the slip-hole of our HDG Bolt Eyelets with proper clearance tolerances to easily slide over the extra thickness of a Hot Dip Galvanized machine bolt. Linemen will experience a smooth, hassle-free fit in the field.
Q5: Can I use a cast iron eyelet instead of a drop-forged one to save money?
A: It is highly discouraged for guy wire applications. Guying systems are subjected to extreme, dynamic tension from wind and ice loads. Drop-forged carbon steel provides vastly superior tensile strength, impact resistance, and grain structure compared to brittle cast iron, ensuring your overhead infrastructure will not fail under stress.
