This guide is for individuals and professionals requiring robust load connection solutions. The SecureFix Direct Dee Shackles, pack of 2, offer a reliable 0.75 Ton (750KG) Safe Working Load, manufactured from high-tensile steel to British Standard BS 3032. A key benefit is their screw pin design for secure fastening, though users should note the 'Self Colour' finish may require specific handling to prevent surface rust over time. Key features include high tensile steel construction, BS 3032 compliance, a 5:1 safety factor, and a screw pin for secure closure.

'Self Colour' refers to the natural finish of the steel without any plating or coating. This means the surface is bare steel and can develop a protective layer of surface rust over time, especially when exposed to moisture. Regular maintenance is advised.
The Safe Working Load for this pack of SecureFix Direct Dee Shackles is 0.75 Ton, which is equivalent to 750 Kilograms.
These shackles meet British Standard BS 3032 and have a 5:1 safety factor, which generally makes them suitable for lifting applications. However, always consult relevant safety regulations and ensure the shackle is correctly rated and used for the specific application. The screw pin must be fully secured.
The screw pin should be tightened as much as possible by hand. For critical applications, it is recommended to use a suitable wrench to tighten the pin further, ensuring it is snug and does not have any play. Inspect visually and by feel before each use.
Light surface rust typically does not significantly impact the overall strength of high-tensile steel. However, deep pitting or significant corrosion can weaken the material. Regular cleaning and lubrication will help prevent detrimental corrosion.
The key dimensions are: A (width): 12.5MM, B (length): 16MM, C (external length): 51MM, D (external width): 30.5MM, E (internal length): 29.5MM.
A 5:1 safety factor means the shackle's ultimate breaking strength is five times its Safe Working Load. This provides a significant margin of safety against unexpected shock loads or stresses during operation.
Clean the threads of the pin and the shackle body with a wire brush. Apply a small amount of lubricant (e.g., grease or penetrating oil) to the threads and work the pin back and forth until smooth.
This is normal for 'Self Colour' steel. Clean the rust off with a wire brush and apply a protective coating of oil or grease. Store in a dry place when not in use.
Immediately remove the shackle from service. Inspect for bending, cracking, or excessive wear. Replace if any damage is found to ensure safety.
Check for debris in the shackle body or on the pin threads. Ensure the pin is aligned correctly before attempting to screw it in. Do not force the pin; if it doesn't seat smoothly, investigate the cause.
Setup: To use the shackles, unscrew the pin completely. Pass the shackle through the loop of the item to be connected (e.g., a rope, chain, or eye). Insert the screw pin back into the shackle body and tighten it fully by hand until it is snug. Ensure the pin is seated correctly and fully engaged for maximum safety. It is recommended to tighten the pin further with a suitable tool if required by the application, but avoid over-tightening which could damage the threads.
Compatibility: These shackles are designed to connect various lifting and rigging components. They are compatible with standard ropes, chains, webbing slings, and eye bolts that fit within the shackle's internal dimensions (approx. 16mm width, 29.5mm internal length). Always ensure the component being attached also meets or exceeds the required load rating.
Care: Due to the 'Self Colour' finish, these shackles may develop surface rust over time, especially in humid or wet conditions. To maintain performance and appearance:
