How It Compares With The Alternatives
An honest read on where this pattern wins and where another one would serve you better.
| Alternative | Honest Trade Off |
|---|---|
| Turnbuckle with eye and hook ends | The jaw-jaw version eliminates the need for separate hooks or eyes, reducing parts and simplifying connection in tight spaces |
| Turnbuckle with screw pin | Jaw ends allow direct attachment without a pin, reducing the risk of pin loss or misalignment during use |
| Non-galvanized turnbuckle | Hot-dipped galvanizing extends service life in wet, salty, or outdoor environments where rust is a concern |
| Cast turnbuckle | Drop forged construction offers higher strength and impact resistance compared to cast parts |
Use Guide
How To Use And Inspect Jaw Jaw Turnbuckle US Type Drop Forged HG-228
- Match the stamped working load limit to the calculated load, not the equipment rating
- Ensure both jaws are fully engaged with the connected component to prevent slippage
- Tighten gradually and check alignment to avoid side loading or bending stress
- Inspect the galvanized coating regularly for damage in corrosive environments
- Retire the turnbuckle if the body shows deformation, the jaws are cracked, or the marking is illegible
- Use only with compatible hardware such as hooks, shackles, or anchor points
- Avoid over-tightening beyond the take-up length specified in the size table

Answers
Jaw Jaw Turnbuckle US Type Drop Forged HG-228 FAQ
What does 'jaw-jaw' mean on a turnbuckle?
It means both ends of the turnbuckle have jaws, allowing direct attachment to hooks, shackles, or anchor points without needing additional fittings. This simplifies rigging and reduces part count.
Is this turnbuckle suitable for overhead lifting?
Yes. It is rated for overhead lifting with a 5:1 safety factor and proof load tested. Use only when the load is aligned with the axis of the turnbuckle.
What is the safety factor and how is it tested?
The safety factor is 5:1. Every batch is proof load tested, and breaking strength is validated to be five times the working load limit.
Can I get a Material Test Certificate?
Yes. A Material Test Certificate to EN 10204 3.1 is supplied with every order. It confirms the material composition and mechanical properties of the forged steel.
What finishes are available?
Standard finish is hot-dipped galvanized. Custom options include zinc plating, powder coating, and electrophoretic black. Stainless steel is available on request.
How are they packed for export?
Packed in cartons or gunny bags on pallets as standard. We can configure the carton count and pallet pattern to match your warehouse or retail requirements.
What sizes and load limits are available?
Sizes range from 1/4”×4” to 2-3/4”×24”. Working load limits range from 400 lbs to 34,000 lbs. The full size table is available in the product data sheet.
