Clevis
Clevises are provided as components of tie rod assemblies that Portland Bolt manufactures and are often used in conjunction with
turnbuckles. In a typical cross bracing assembly, a threaded rod is supported at each end by a clevis. One end of each clevis will grip onto a steel plate and is secured with a pin.
When a single tie rod is used between two clevises, one end of the assembly uses right hand thread and the other end uses left hand thread. As the rod is turned, the assembly draws tight. When a turnbuckle dissects the rod assembly, both clevises (and the end of the rods threading into them) will use right hand thread. The opposite end of one of the two rods which make up the assembly will require left hand thread to mate with the turnbuckle.
AVAILABILITY
Clevises are not a stocked item but are available within a day or two. Clevises are provided in both plain finished and hot-dip galvanized medium carbon steel as well as stainless steel. Custom and nonstandard clevises are also available.
