Our carbon steel button stops are machined from material specially selected for swaging. All carbon stops are designed to be machined swaged only. Compression via hydraulic press is required to achieve the correct post-swage diameter.
Note: The holding strength of a carbon steel button stop is affected by the construction of the cable onto which it is installed. A button stop installed on a 7x7 cable will yield a different holding strength than an identical button stop installed on a 1x19 cable, for example.
