Heavy Duty Hitching Ring Screw / Screw with Loose Ring (Tie Down Anchor) – Zinc Plated – Manufacturer Direct

Heavy Duty Hitching Ring Screws: The Ultimate Swivel Tie-Down Solution

At Handan Bolt, we manufacture industrial-grade Hitching Ring Screws, also known in the hardware trade as Screw Eyes with Loose Rings or Swivel Ring Screws. Produced in our Yongnian facility, these fasteners are designed for dynamic load applications. Unlike a standard rigid eye bolt, the ring on this screw swings freely, making it the superior choice for securing ropes, cables, and chains that may move or change angles.

What is a Hitching Ring Screw?

A Hitching Ring Screw combines a heavy-duty wood Screw (Read more on Wikipedia) with a captured, freely moving steel ring. The head of the screw is specially formed to hold the ring securely while allowing it to pivot 180 degrees. This “swivel action” is crucial because it ensures that side-pulls or angular tension do not unscrew the fastener from the wood, a common failure point with standard fixed eye screws.

Why Choose a Loose Ring Over a Fixed Eye?

The “Loose Ring” design offers distinct mechanical advantages:

• Stress Reduction: When a load pulls sideways, the ring pivots to align with the force, reducing bending stress on the screw shank.
• Anti-Loosening: Since the ring moves independently of the screw, the rotation of the attached rope or animal won’t accidentally unscrew the fastener.
• Flexibility: It lays flat against the surface when not in use, creating a lower profile than a rigid eye bolt sticking straight out.

Material Grades and Durability

We manufacture these anchors to withstand heavy abuse and outdoor elements:

1. Carbon Steel (Zinc Plated)

Our standard model is made from high-tensile Carbon Steel and finished with a thick layer of Blue/White Zinc Plating (Galvanized). This finish provides excellent rust protection for barn, garage, and general outdoor use. It is the most cost-effective option for high-volume hardware sales.

2. Stainless Steel (304 / 316)

For marine environments (boat decks, docks) or harsh chemical settings, we offer Stainless Steel Hitching Rings. These are completely resistant to corrosion and maintain their strength even after decades of exposure to salt water.

Versatile Applications

Originally designed for agriculture, these screws have found their way into many industries:

• Animal Restraint (Hitching): Commonly screwed into wooden posts to tie up horses, cattle, or pets. The swivel ring prevents the lead rope from twisting.
• Cargo Tie-Downs: Installed on the wooden floors of trailers or trucks to anchor straps for securing loads.
• Playground Equipment: Used to anchor ropes and swings where movement is constant.
• General Rigging: Securing tarps, tents, and awnings where wind causes the tie-down lines to move.

Installation Guide

Installing a Hitching Ring Screw is simple but requires care to ensure maximum holding power:

1. Pilot Hole: Always drill a pilot hole (approx. 70% of the screw’s shank diameter) to prevent splitting the wood.
2. Drive In: Unlike a hex bolt, this screw doesn’t have a hex head. You can drive it in by inserting a sturdy screwdriver or metal rod through the ring and using it as a lever to twist the screw deep into the timber.
