Turnbuckles & Turnbuckles assemblies

TURNBUCKLES

During the fabrication process, turnbuckles are drop forged from special bar quality steel, threaded right and left hand Class 2B and supplied either plain finish to hot-dip galvanized.

Galvanizing meets or exceeds requirements of ASTM Specification A 153.

Stubs are made from Hot Rolled Mild Carbon Steel.

Max Work Loads

Working Loads

Maximum working loads have been established with a design factor of 5:1 or 3:1 (AISC) and are calculated using C-1030/C-1035 Carbon Steel. Maximum Working load results on other materials offered are available upon request. The loads imposed upon any turnbuckle should never exceed the maximum working load shown. Selection of a turnbuckle with a maximum working load adequate to meet the required design load is the responsibility of each purchaser or end user. The turnbuckles meet the requirements of ASTM F1145-92 Type 1 Grade 1, up to 2 1/2”.
