No-Wrench Screw Anchor | Thimble Eye Guy Anchor | Yokelink
Reliable Manual-Install Guying for Utility Applications. The Yokelink No-Wrench Screw Anchor is engineered for secure guy wire anchoring in various soil classes. Designed for straightforward installation, these anchors do not require specialized Kelly bar adapters or wrenches. They can be installed either manually by inserting a turning bar through the forged eye or by using machine power adapted to the eye.
Structural Integrity and Penetration: Each anchor features an integrally forged Thimble Eye (Single or Triple) to protect the guy strand, seamlessly attached to a high-strength steel rod. The helix (screw plate) is precision-pitched and securely welded to the rod, allowing for smooth earth penetration with minimal soil disturbance. This design maximizes the undisturbed soil column above the helix, providing exceptional pull-out holding capacity.
All Yokelink No-Wrench Anchors are Hot Dip Galvanized to ASTM A153 specifications to resist corrosion in highly aggressive soil environments, ensuring long-term structural stability for overhead polelines.
Key Technical Features of No wrench Anchor
Installation: "No-Wrench" design allows for manual or light-machine installation via the eye.
Eye Type: Drop-forged Single or Triple Thimble Eye to prevent guy wire kinking.
Helix Design: Sharpened leading edge and precise pitch for fast, low-disturbance soil penetration.
Finish: Fully Hot Dip Galvanized (HDG) for extended underground service life.
Production Process of No Wrench Anchor
No wrench anchors are made from high-strength carbon steel rod. After straightening and cutting, the anchor body is formed by hot forging to create its unique wedge‑expansion structure. Threads are processed by precision thread rolling. Heat treatment is applied to ensure stable mechanical properties and tensile strength. The finished anchors are 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 No Wrench Anchor
No wrench anchors are widely used in overhead transmission and distribution lines for underground anchoring and guying systems. They provide secure, stable foundation support without additional tightening tools during installation. Featuring high tensile strength and reliable expansion locking structure, they resist loosening under long-term tension and outdoor conditions. Hot-dip galvanized per ASTM A153 for excellent corrosion resistance and compliant with IEEE C135.2 and ANSI C135.90 standards, they ensure safe, durable, and low-maintenance performance in power line anchoring 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: Why is it called a "No-Wrench" anchor?
A: It is called a "No-Wrench" anchor because its installation does not require a specialized driving wrench or a hollow Kelly bar adapter. The anchor is installed simply by inserting a heavy steel turning bar through the forged eye and rotating it manually, or by attaching a machine adapter directly to the eye.
Q2: How does the helix pitch affect the anchor's installation and holding power?
A: The pitch of the helix plate is precisely engineered to act like a screw. A correct pitch allows the anchor to thread into the ground with minimal disturbance to the surrounding soil. Preserving the natural compaction of the soil column directly above the helix is critical, as this undisturbed earth provides the resistance (holding capacity) against pull-out forces.
Q3: Can No-Wrench anchors be installed in rocky soil?
A: No-Wrench screw anchors perform best in standard to firm soils (Soil Classes 3 through 7), such as clay, sand, and regular earth. They are not recommended for extremely rocky soil or solid rock installations, as the rocks can deform the helix pitch or block penetration. For rocky terrain, rock anchors or expanding anchors are technically more appropriate.
