Webnet Stamped Bow Shackle Screw Pin Light Duty 316 SS For Heavy Industry Lifting

Marine Grade 316 SS Stamped Bow Shackle Screw Pin Light Duty – For Marine, Heavy Industry Lifting & Webnet

1. Product Description

The Marine Grade 316 SS Stamped Bow Shackle Screw Pin Light Duty is a versatile, corrosion‑resistant lifting and rigging component engineered for light‑duty applications in marine environments, heavy industry, and webnet (safety net) tensioning systems. Manufactured from premium marine grade 316 stainless steel via a stamping process, this bow shackle delivers exceptional resistance to saltwater, chlorides, and harsh marine conditions-. Grade 316 stainless steel contains molybdenum (2‑3%), providing superior corrosion resistance compared to 304 grade, particularly in saltwater and chemical environments-.

The shackle features a screw pin design for secure fastening, allowing quick and easy installation and removal without tools-. The bow (anchor) shape provides a wider radius than D‑shackles, accommodating multiple sling legs, larger shackles, or rope eyes without pinching. It is 100% load tested and available in metric sizes from 4 mm to 8 mm, with breaking loads ranging from 600 kg to 2,600 kg. The polished surface finish provides a smooth, rust‑resistant, professional appearance.

Fully customizable in size, diameter, length, width, packaging, logo, color, and surface finish. Free samples are supported, with door‑to‑door service available. Ideal for yacht rigging, camping, light lifting, trailer lashing, marine hardware, and webnet systems.

2.Product Attributes

Additional Specifications:

• Material: Marine grade 316 stainless steel. Other grades (304) available on request.

• Surface finish: Polished (bright). Other finishes (passivated, electro‑polished) available.

• Pin type: Screw pin (fully removable). Also available with bolt type (nut and cotter pin)-.

• Stamped construction – Lightweight yet strong, easy to handle and store. Stamped shackles are appropriate for low‑load applications-. For higher loads, forged shackles are recommended-.

• Screw pin design – Quick installation and removal, no tools required-. The screw pin is fully removable from the shackle, allowing easy connection and disconnection.

• Polished surface finish – Smooth, rust‑resistant, professional appearance; reduces crevices and makes cleaning easier.

• Wide size range – Available from 4 mm to 8 mm with breaking loads from 600 kg to 2,600 kg, suitable for light‑duty lifting, lashing, and rigging.

• Light duty applications – Ideal for yacht rigging, camping, trailer lashing, light lifting, and general marine use.

• 100% load tested – Each shackle is proof‑tested to its rated breaking load, ensuring safety and reliability.

• Fully customizable – Surface treatment, material, diameter, length, packaging, logo, and color can be tailored to customer requirements.

• Free samples supported – Test quality before bulk order.

4. Applications

The Marine Grade 316 SS Stamped Bow Shackle Screw Pin is used in numerous light‑duty fields:

• Marine rigging & yacht hardware – Anchor chain connections, dock line attachments, sailboat rigging, yacht mooring, deck hardware-.

• Camping & outdoor – Tent tie‑downs, tarp securing, hammock hanging, general outdoor rigging.

• Light lifting – Small hoist connections, workshop lifting, light equipment handling.

• Trailer lashing & cargo securement – Tie‑down straps, trailer cover fastening, light cargo binding.

• Webnet (safety net) systems – Tensioning and connecting stainless steel wire rope nets (webnets) for light‑duty rockfall barriers, animal enclosures, and sports barriers.

• General industrial – Machinery fixing, agricultural equipment, stage rigging, light duty towing-.

• Heavy industry light duty – Small part securing, temporary rigging connections, maintenance work.

5. Technical Principles

5.1 Material & Stamping Process

316 stainless steel provides excellent tensile strength and corrosion resistance in marine and industrial environments-. The molybdenum content in Grade 316 delivers better overall corrosion resistance than Grade 304, particularly against chlorides in saltwater-. The stamping process creates the shackle shape from flat sheet metal, resulting in a lightweight component suitable for low‑load applications-. For higher loads, forged shackles are recommended-.

5.2 Bow Shape & Load Distribution

The bow (anchor) shape provides a wider radius than D‑shackles, accommodating multiple sling legs or larger rope eyes without pinching. The rounded geometry distributes tensile forces evenly, minimizing stress concentration at the pin holes.

5.3 Safety Factor

Shackles are designed with a safety factor of 4:1 or 5:1 (breaking load / working load limit). For example, a shackle with a breaking load of 2,600 kg (8 mm) has a WLL of approximately 520–650 kg. Users must never exceed the WLL and must account for dynamic loads, angle of pull, and wear.

5.4 Screw Pin Mechanism

The screw pin is fully removable from the shackle-. After inserting the pin through the shackle ears and the attached component, it is tightened securely. The screw pin provides quick and easy installation and removal without tools.

5.5 Corrosion Resistance

316 stainless steel forms a passive chromium oxide layer that protects against rust-. The polished surface reduces crevices and makes cleaning easier-. For saltwater environments, Grade 316 is the preferred choice for marine use-.

5.6 Load Testing & Traceability

Each shackle is proof‑loaded to 100% of its rated breaking load. Permanent markings (size and grade) are stamped on the body for traceability.
