Overview: This document provides technical specifications for stainless steel double swivel shackles with both metric and UNC threads. It includes details on working load limits (WLL), safety factors, dimensions, and weights.
Metric Threads:- Specifications: The document lists various models of shackles with metric threads, specifying the reference diameter, safety factor (SF) of 5:1 and 4:1, working load limits (WLL) in tons, standard length (L1), and required torque in Nm.
- Dimensions: Key dimensions such as A, B, C, D, E, F, and G are provided in millimeters, along with the weight in kilograms and pounds.
- Models: Examples include SS.DSS M 24, M 30, M 33, M 36, and others, with varying WLL and dimensions.
UNC Threads:- Specifications: Similar to metric threads, the document details shackles with UNC threads, including reference diameter, safety factors, WLL in pounds, standard length (L1), and torque in ft-lb.
- Dimensions: Dimensions are provided in millimeters, with weight in kilograms and pounds.
- Models: Examples include SS.DSS U 100, U 125, U 138, U 150, and U 200, each with specific WLL and dimensions.
Key Observations:- Both metric and UNC thread models maintain consistent dimensions for certain parameters, such as A, B, C, D, E, F, and G, across different models.
- The document emphasizes the importance of torque specifications for proper installation and safety.
