Product Description

No-Wrench Screw Anchor is also called Earth Helix Screw Anchor, it is a type of earth anchor, that functions by guying wires or cables within utility poles. It comprises an anchor rod of forged-eye, angle-cut tip, and a welded helix.

Both the Triple eye and the Thimble eye Eye anchors have a rod with an enormous opening to support a turning bar that ensures the anchor is screwed on the ground. The No wrench screw is installed by turning it into the ground by a machine or hand, the extension rod ensures installation to a depth CHINAMFG the firm soil.

The anchor can be power-installed due to its eye that engages in the adapter of the hole-boring machine. The wrench anchor serves best in loose to medium-dense soils. After installation, the exposed anchor should have a final height of 8-12 inches extending the grade height.

When the No-Wrench anchor is hand installed, it reduces the holding capacity by about 10-20%.  Failure to adhere to the 5° installation alignment with the guying mass will significantly minimize the strength. The capacity ratings are only applicable to anchors that are properly installed.

The no wrench screw anchor is a type of earth anchor; it functions by basically guying cables or wires within utility poles, which is comprised of an angle-cut tip, welded helix and an anchor rod of forged-eye.

The No-Wrench Anchor can be placed with power equipment or by hand. MPS No-Wrench Anchors are made of a forged eye anchor rod with a welded helix and angle cut tip.

These anchors are ideal for use in medium dense to loose soils. Final installed height of the exposed anchor should be 8 to 12 inches above grade level. No-Wrench anchors are Hot Dip Galvanized per ASTM A123.

What are the signs that indicate a need for eye bolt screw replacement or maintenance?

Eye bolt screws require regular inspection to identify signs of wear, damage, or other issues that may necessitate replacement or maintenance. Detecting these signs early helps prevent failures, ensure safety, and maintain optimal performance. Here’s a detailed explanation of the signs that indicate a need for eye bolt screw replacement or maintenance:

  • Visible Damage: Inspect the eye bolt screws for visible signs of damage, such as cracks, bending, or deformation. Any visible damage indicates a potential weakness that can compromise the structural integrity of the screws.
  • Thread Damage: Examine the threads of the eye bolt screws for signs of wear, stripping, or cross-threading. Damaged threads can result in reduced strength, improper engagement, or difficulty in tightening or loosening the screws.
  • Corrosion: Check for signs of corrosion on the surface of the eye bolt screws. Corrosion can weaken the material and compromise the load-carrying capacity of the screws. Look for rust, pitting, or discoloration, especially in outdoor or corrosive environments.
  • Loosening: If eye bolt screws consistently loosen or require frequent retightening, it may indicate a problem. Check for proper torque and ensure that the screws remain securely fastened. Persistent loosening may be a sign of thread damage, insufficient engagement, or inadequate tightening.
  • Excessive Wear: Evaluate the overall condition of the eye bolt screws for signs of excessive wear. This includes wear on the shank, head, or bearing surfaces. Excessive wear can reduce the load capacity and compromise the performance of the screws.
  • Noise or Vibration: Unusual noises, vibrations, or rattling during operation can indicate loose or damaged eye bolt screws. If the screws are not securely fastened or if there is excessive clearance, it can lead to unwanted movement, noise, or vibration.
  • Deformation of Connected Components: Monitor for signs of deformation or damage in the components connected to the eye bolt screws. If the connected components show signs of stress, bending, or deformation, it may indicate issues with the screws or improper load distribution.
  • Change in Load Capacity: If the load requirements change or increase for the application, it is important to reassess the load capacity of the eye bolt screws. If the screws are not rated to handle the new loads, replacement or reinforcement may be necessary.

Regular inspections and prompt action based on these signs are critical to maintaining the integrity and performance of eye bolt screws. When any of these signs are detected, it is advisable to consult the manufacturer’s recommendations, industry standards, or seek the expertise of a qualified professional to determine the appropriate course of action, whether it involves replacement, repair, or maintenance.

By staying vigilant and addressing potential issues in a timely manner, you can ensure the reliability, safety, and longevity of eye bolt screws in various applications.

How do eye bolt screws contribute to load-bearing and lifting operations?

Eye bolt screws play a crucial role in load-bearing and lifting operations by providing a secure and reliable attachment point for connecting lifting equipment, such as ropes, cables, or chains, to the load being lifted. Here’s how eye bolt screws contribute to load-bearing and lifting operations:

  1. Attachment Point: Eye bolt screws feature an eye or loop at one end, which serves as the attachment point for lifting equipment. The shape and design of the eye provide a secure and properly fitting connection for the hardware used in lifting operations, ensuring that the load remains stable and properly supported during lifting.
  2. Load Distribution: When a load is attached to an eye bolt screw, the screw transfers the weight and forces exerted by the load to the surrounding structure or support system. The eye bolt screw acts as a load-bearing component, distributing the load evenly across its body and the attachment point. This helps prevent concentrated stress on a single point, reducing the risk of failure or damage.
  3. Strength and Load Capacity: Eye bolt screws are designed and manufactured to have high load-bearing capacities to withstand the forces encountered during lifting operations. They are made from materials with sufficient tensile and yield strength, ensuring that they can handle the expected loads without deformation or failure. The load capacity of an eye bolt screw is typically specified by the manufacturer and should not be exceeded to maintain safety.
  4. Flexibility and Versatility: Eye bolt screws come in various sizes, shapes, and configurations, allowing them to be used in a wide range of load-bearing and lifting applications. They can be installed in different orientations, such as vertical, horizontal, or angled, depending on the specific lifting requirements. This flexibility makes eye bolt screws adaptable to different lifting scenarios and enables them to accommodate various hardware and equipment.
  5. Safety Considerations: Eye bolt screws are subject to specific safety guidelines and standards to ensure their proper use in load-bearing and lifting operations. These guidelines may include factors such as proper installation torque, inspection and maintenance requirements, and load capacity limitations. Adhering to these safety considerations helps minimize the risk of accidents, load failures, or injuries during lifting operations.

Overall, eye bolt screws provide a critical link between the load and the lifting equipment, enabling safe and efficient load-bearing and lifting operations. Their strength, reliability, and versatility make them indispensable components in various industries, including construction, manufacturing, rigging, and material handling.
