High-Capacity Anchoring for Augered Holes.
The Yokelink Bust Expanding Anchor is engineered to provide massive holding capacity for utility pole guying systems. Designed for installation in pre-augered holes, these anchors rely on the mechanical expansion of their ribbed steel blades into undisturbed soil, making them highly effective in a wide range of soil classes.
Mechanical Expansion and Load Distribution:
Available in 4-way and 8-way plate configurations, the anchor features heavily ribbed blades stamped from high-strength carbon steel. Once lowered to the bottom of the augered hole, a mechanical tamping tool is used to strike the anchor base. This action forces the blades to expand outward and bite deeply into the solid, undisturbed earth walls. The multiple-blade design ensures that the tension load from the guy wire is distributed evenly across a large surface area of soil, maximizing pull-out resistance.
Yokelink Expanding Anchors are designed to be assembled with standard IEEE C135.2 drop-forged anchor rods. To protect against severe underground corrosion, the anchors are typically coated with a heavy asphalt paint or fully Hot Dip Galvanized (HDG) to ASTM A153 specifications.


Key Technical Features of Bust Expanding Anchor
Configurations: 4-way and 8-way expanding blade designs for optimal load distribution.
Installation: Requires an augered hole and a tamping tool for mechanical expansion.
Structural Design: Ribbed steel blades provide high rigidity and prevent bending under tension.
Compatibility: Features a standard nut retainer to accept 5/8", 3/4", or 1" threaded anchor rods.
Production Process of Bust Expanding Anchor
Bust expanding anchors are made from high‑strength carbon steel. The process begins with material straightening and cutting to length. The anchor body and expansion sections are formed by hot forging to ensure structural integrity. Threads are precision rolled for consistent fit. Heat treatment is applied to achieve required tensile and mechanical properties. The anchors are then hot‑dip galvanized in accordance with ASTM A153 for corrosion resistance.

Yokelink Quality Control and Testing Equipments
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 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.

The Application of Bust Expanding Anchor
Bust expanding anchors are widely used in overhead transmission and distribution lines for underground guying and anchoring systems. They provide reliable ground anchoring for poles, guy wires and stay assemblies. With a strong expanding locking structure, they deliver high pull-out resistance and stability in various soil conditions. Hot-dip galvanized in accordance with ASTM A153, they offer excellent corrosion resistance. Compliant with IEEE C135.1 and ANSI C135.90 standards, they ensure safe, durable and maintenance-free performance in long-term power line applications.
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 difference between an 8-way and a 4-way expanding anchor?
A: The difference lies in the number of expanding blades and how they distribute the load. An 8-way anchor utilizes eight separate blades that expand outward to form a wide, octagonal bearing surface against the soil. A 4-way anchor uses four larger blades. Both designs are highly effective, but the choice often depends on the required expanded area (square inches) and the specific soil class of the installation site.
Q2: How does a Bust expanding anchor connect to the guy wire?
A: The anchor itself is buried underground. It features a base plate with a nut retainer. Before dropping the anchor into the augered hole, a threaded Anchor Rod (such as a drop-forged thimble eye rod) is screwed into the anchor's base. Once the anchor is expanded and the hole is backfilled, the guy wire is attached to the eye of the anchor rod above ground.
Q3: Why is proper tamping critical during installation?
A: Expanding anchors derive their holding capacity from pushing their blades into the undisturbed earth on the sides of the augered hole. A heavy expanding and tamping tool must be used to strike the anchor repeatedly until the blades are fully extended. Furthermore, the soil used to backfill the hole must be thoroughly tamped down in layers to ensure maximum density and resistance against pull-out forces.
