Product Description
5/8" Thimble Eye Bolt | Drop Forged | IEEE C135.80
Yokelink 5/8" Thimble Eye Bolts are specifically designed for direct guy strand attachment. The heavily contoured, grooved eye eliminates the need for a separate guy thimble, saving both component costs and installation time on the pole.
Forged from a single piece of high-grade carbon steel, these bolts deliver a minimum tensile strength of 12,400 lbs. Finished with heavy-duty Hot Dip Galvanizing (ASTM A153 Class C), they offer exceptional corrosion resistance, making them fully compliant for use in extreme coastal and desert environments (meeting SEC and international utility standards).
Thimble Eye Bolt Key Features:
Contoured Eye: Grooved design protects guy strands from bending stresses.
Process: Drop Forged (One-piece construction, zero welds).
High Strength: Meets IEEE C135.80 minimum tensile rating of 12,400 lbs.
Weather Proof: Premium HDG finish for harsh environments.
Assembly: Supplied with one square nut and a standard cone point.
Thimble Eye Bolt Factory Production Process:
The production of thimble eye bolts must adopt hot forging . Made from ASTM A307 carbon steel, the bar is heated to 1100–1200℃ for hot forging to form the thimble eye and shank blank, followed by trimming and annealing to eliminate internal stress. After precision machining and thread rolling, heat treatment is performed to ensure mechanical properties. Surface treatment is hot-dip galvanizing per ASTM A153 for corrosion resistance, with the entire process and inspection complying with IEEE C135.1 and IEEE C135.80 for overhead line applications.
Yokelink Quality Control and Testing Equipments
![thimble eye bolt testing]( "thimble eye bolt testing")
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 C135.1 / IEEE C138.80 or CSA 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.
Key Application Scenarios of Thimble Eye Bolt:
Thimble eye bolts are widely used in overhead transmission and distribution lines as reliable connecting and anchoring fasteners. They are mainly used for guy wires, stay rods, cross arms and pole fixtures, providing stable tensile support and strong wear resistance. Manufactured in line with IEEE C135.1 and IEEE C135.80 standards, with ASTM A307 material and hot-dip galvanized coating per ASTM A153, they ensure long service life and safe operation in outdoor power line systems.
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)
1.Q:Can I use Yokelink poleline fasteners bolts to replace Hubbell or MacLean parts?
A: Yes. Our poleline hardware bolts are functionally equivalent and interchangeable with industry-standard part numbers such as the Hubbell 55xx series and MacLean J80xx series. They meet or exceed the same mechanical load ratings
2.Q: Do you provide Mill Test Reports (MTRs) ,Drawing, or Factory Inspection Reports?
A: Yes, transparency is our standard. Full Mill Test Reports, Galvanizing Certificates, and Factory Inspection Reports are available with every shipment upon request, traceable to the raw material heat number.
3.Q:Are your products suitable for harsh environments?
A:Yokelink machine bolts are specifically processed with Heavy-Duty Hot Dip Galvanizing (ASTM A153 Class C) to withstand the extreme heat, UV exposure, and high salinity conditions typical of the Middle East (KSA) region. Ideal for SEC (Saudi Electricity Company) distribution.
4.Q: Do I need a separate thimble with this bolt?
A: No. The contoured eye is designed to seat the guy strand directly, preventing deformation and saving hardware costs.
