1. What is a Stainless Steel Screw Pin D Shackle?
A Stainless Steel Screw Pin D Shackle, also known as a Bow Shackle, is a "D"-shaped, high-strength metal connecting link used in rigging, lifting, and securing applications. It features a removable screw pin that allows for easy attachment and detachment of slings, ropes, chains, and other hardware. The stainless steel construction provides excellent corrosion resistance for marine, chemical, and outdoor use.
2. What are the main differences between AISI 304 and AISI 316 stainless steel?
AISI 304 (A2): General-purpose stainless steel with excellent corrosion resistance in most environments. It is the most common and economical choice for standard industrial and marine applications.
AISI 316 (A4/Marine Grade): Contains molybdenum (Mo), which provides superior resistance to chlorides (salt water), acids, and industrial chemicals. It is the premium choice for harsh marine (offshore, saltwater), chemical processing, and high-corrosion environments.
For maximum durability in saltwater, 316 is strongly recommended.
3. What are the typical applications?
Our shackles are used wherever a strong, corrosion-resistant connection point is needed:
Marine & Boating: Rigging, sailboat hardware, mooring, anchor points.
Lifting & Rigging: Connecting slings, chains, and hooks in material handling.
Construction & Scaffolding: Securing loads and structural bracing.
Transportation & Trucking: Tie-down points and cargo securing.
Industrial Manufacturing: Process equipment, safety barriers, machinery.
Outdoor & Architectural: Decorative or functional fittings exposed to weather.
4. What are the key specifications and size markings?
Shackles are defined by several key specs:
Diameter (D): The body diameter (also called "nominal size") in mm or inches (e.g., 6mm, 1/2", 13mm, 3/4").
Working Load Limit (WLL): The maximum safe load in perfect, straight-line tension. Clearly stamped on the shackle body (e.g., 1T, 3.25T, 4.75T).
Material Grade: Stamped as "304" or "316".
Safety Factor: Typically designed with a minimum 5:1 safety factor against the minimum breaking load (MBL).
5. How do I choose the correct size?
Selection is based on the Working Load Limit (WLL) required for your application.
Calculate the maximum load that will be applied to the shackle.
Select a shackle whose WLL exceeds this load. Always include a safety margin.
Ensure the shackle's bow and pin diameter are large enough to accommodate the slings, hooks, or hardware you are connecting.
We provide detailed WLL tables for each size in metric and imperial tons.
6. What is the proper way to load a D shackle?
For safety and strength, a shackle should always be loaded in-line (straight pull) on its center axis. Side loading or loading across the pin significantly reduces its capacity and is dangerous. Use a bow shackle over a chain shackle when multiple connections or angular loads might occur.
7. How is the screw pin secured?
The screw pin has a standard or fine thread. For secure use:
Hand-tighten the pin fully.
For critical or vibrating applications, it is common practice to "finger-tighten plus a quarter turn" using a tool. DO NOT OVERTIGHTEN, as this can gall the threads, especially in stainless steel.
Some users apply a light thread-locking compound for long-term applications in high-vibration environments.
Always visually check that the pin is fully seated and the collar is flush with the shackle ears.
8. How do I request a quotation?
For a quick and accurate quote, please specify:
Size/Diameter (e.g., 10mm, 1/2") or WLL required.
Material (304 or 316).
Quantity needed.
Any special requirements (marking, packaging).
9. Do you offer different pin types?
While screw pin is our standard for versatility, we also offer:
Bolt Type Shackles: With a nut and cotter pin for more permanent or higher-security applications.
Round Pin Shackles: For non-lifting, tie-down applications.
Available upon request and subject to MOQ.
10. Can you provide custom markings or OEM services?
Yes. We offer full OEM customization:
Custom WLL stamping and logo marking.
Special sizes or materials.
Private label packaging (poly bags, boxes).
Bulk packaging for distributors.
11. What is your MOQ (Minimum Order Quantity)?
Standard Sizes (304/316): MOQ 500 pieces per size (can be mixed across sizes to meet MOQ).
Custom Marking/OEM: MOQ 1,000 pieces.
Samples: Available for evaluation.
12. What is your production lead time?
Samples: 7-10 working days.
Standard Order: 15-25 working days.
Custom Order: 25-35 working days after confirmation.
