Swage Forks
Hayn Swage Forks are Type 316 stainless steel clevis fork wire terminals available across one of the broadest size ranges in the catalog, covering imperial wire diameters from 1/8" through 1" and metric wire diameters from 3mm through 26mm with multiple pin diameter options on several wire sizes.
Swage Forks
The swage fork creates a permanent, high-strength clevis connection at the wire end that integrates directly with toggles, turnbuckles, chainplate fittings, and other pin-connected hardware throughout the rigging system. Multiple pin diameter options on certain wire sizes — standard, DS (down-size), and US (up-size) configurations — allow riggers to match the fork to the specific pin diameter of the receiving fitting without being locked into a single pin size per wire diameter. Full swage specifications are available on the Hayn website, and hardware factor dimensions are published for all imperial and metric configurations to simplify total assembly length calculations.
