Sleeve Nuts are used to couple tie rods of the same 
diameter and provide a limited degree of length adjustment (typically 4-5 inches). They are often used in place of turnbuckles when high strength rods are specified. Normally sleeve nuts come with right hand thread on one end and left hand thread on the other end to allow tension to be put in the assembly. Sleeve nuts are different than Coupling Nuts in that they have right and left hand threads, normally include a non-threaded (stopper) section in the middle of the nut and are longer than Coupling Nuts. Chemically they match the A563 & A194 nut specifications.
Finishes: Plain (black) Hot Dip Galvanized, Zinc Plated
Standard sleeve nuts are produced from ASTM A108 grade 12L14 hexagon or round bars with 50 Ksi minimum yield strength. Other available materials include 1045, 4140, structural grades and stainless steels.

Notes: In order to meet high strength requirements, the rods must be threaded into the sleeve nut for a distance equal to or greater than the thread size.
