1/2" Welded High Test Chain MPN:678145

The Grade 70 3/8 in. welded chain is made up of individually interlocked links constructed from high tensile steel. Its durability and strength are due to heat treatment, yielding a working load limit capacity of 9,100 pounds. The heavy-duty construction ensures that it is suitable for rigorous applications such as truck or agricultural implements that require securing with security chain requirements, in constructions sites or in marine environments with exposure to harsh conditions where standard chains may rust or corrode. Its resistance to weather and chemicals makes it an ideal choice over conventional malleable iron castings chains of lower tensile strength grades commonly used for towing or security purpose as this can be easily cut with bolt croppers.
