Cromox Shackles
Cromox shackles are stainless steel bow and dee shackles manufactured by the pewag Group per EN 1677, the same standard family that governs chain and hardware components in lifting assemblies. They are specified for rigging in marine, offshore, food processing, pharmaceutical, and chemical environments where a carbon or alloy shackle would corrode in service.
Cromox Stainless Steel Shackles for Corrosion-Sensitive Rigging
Shackles are the connector between a sling and a lifting point, between chain legs and a master link, or between a hook and a rigging assembly. In most industrial rigging, alloy steel shackles handle this job. Alloy is strong, economical, and proven. But alloy corrodes.
In environments with saltwater, cleaning chemicals, humidity, or chemical vapor exposure, a stainless shackle makes sense where alloy would show surface corrosion within a short service window. Cromox stainless shackles are forged from 316L stainless steel (AISI 316L) and manufactured per EN 1677, the European standard for components in slings and lifting assemblies. They carry working load limits and manufacturer markings per the EN 1677 requirements.
The Cromox shackle line covers bow (anchor) and dee (chain) configurations in screw-pin and bolt-type assemblies, depending on the application.
Cromox Shackle Configurations
Bow Shackles (Anchor Type)
Bow shackles have a wider body profile that accepts multiple sling legs in the bow. They are the standard choice for multi-leg sling connections and for any application where the load or sling angle may place a side load on the shackle body. Cromox bow shackles in stainless cover the same connection scenarios as alloy bow shackles, just in a corrosion-resistant material.
Dee Shackles (Chain Type)
Dee shackles have a narrower D-profile body designed for in-line loading, single sling leg connections, chain-to-hardware connections, and applications where the load stays in line with the pin. Cromox dee shackles cover in-line connection applications in corrosive environments.
Screw Pin vs. Bolt Type
Screw-pin shackles use a threaded pin that screws in and out for quick rigging changes. Bolt-type shackles use a bolt with a nut and cotter pin, the cotter prevents the pin from backing out under vibration or rotational loading. In applications where the pin might rotate or back out, bolt type is the standard call. In quick-change applications, screw pin works. Cromox stainless shackles are available in both configurations depending on the model.

Cromox Shackle Applications by Industry
- Marine and Offshore: Deck rigging, mooring hardware, and lifting operations on vessels and platforms exposed to saltwater.
- Food and Beverage Processing: Overhead lifting equipment in processing areas subject to washdown. Stainless shackles do not shed rust.
- Pharmaceutical Manufacturing: Material handling in clean rooms and hygiene-controlled areas where contamination from hardware corrosion is a concern.
- Chemical Processing: Reactor lifts, heat exchanger handling, and sump rigging in chemical splash and vapor environments.
- Wastewater Treatment: Below-grade rigging in wet wells and pump stations with continuous moisture exposure.
Why Holloway Houston
Holloway Houston has distributed rigging hardware from Houston for over 65 years. We stock Cromox stainless shackles because Gulf Coast operations, marine, petrochemical, food, and offshore, regularly need corrosion-resistant hardware that does not require special-order lead times.
Holloway Houston also provides rigging inspection services. Our qualified inspectors examine shackles and hardware per ASME B30.26 and applicable OSHA standards.
Shackle Safety and Awareness
Cromox shackles are load-bearing components subject to ASME B30.26 (Rigging Hardware) for inspection and use in US lifting service. Key awareness points:
- Shackles are marked with WLL and manufacturer identification per EN 1677. Shackles with illegible markings are not suitable for continued service.
- Visual inspection before each use: check pin seated fully, cotter pin intact (bolt type), body free from cracks, deformation, and corrosion beyond surface staining.
- In stainless shackles operating in chloride environments (saltwater, bleach), inspect for pitting corrosion, a specific corrosion mode in stainless that can occur even on marine-grade stainless surfaces.
- The WLL rating applies to the shackle in line with the pin axis. Side-loading a dee shackle reduces the effective capacity.
- Proof test certificates and manufacturer documentation are available through Holloway Houston with purchase.

Frequently Asked Questions
Holloway Houston stocks Cromox stainless shackles in bow (anchor) and dee (chain) configurations, in screw-pin and bolt-type pin assemblies. Cromox shackles are manufactured by the pewag Group per EN 1677. Call 1-888-496-4700 for current models, WLL by size, and availability.
Cromox shackles are manufactured per EN 1677, the European standard for components of slings and lifting assemblies. In US service, shackle inspection and use follow ASME B30.26 (Rigging Hardware) requirements. pewag Group, the manufacturer, is ISO 9001 certified.
Stainless shackles are specified when the operating environment would cause unacceptable corrosion on alloy steel within the service interval, marine, offshore, food processing, pharmaceutical, and chemical plant environments. Alloy shackles carry higher WLL at the same body size; stainless shackles trade capacity for corrosion resistance.
A bow shackle has a wide, rounded body that accepts multiple sling legs and tolerates some side loading on the body. A dee shackle has a narrow D-shaped body designed for in-line loading with a single sling leg or chain. Bow shackles are more common at sling assembly tops; dee shackles appear at chain-to-hardware connections and in-line rigging points.
Screw-pin shackles are used for quick rigging changes where the pin is frequently removed and replaced. Bolt-type shackles, pin, nut, and cotter, are used where the pin might rotate or back out under vibration, sustained loading, or directional load changes. For permanent rigging points, bolt type is the standard call.
