Product Description

Turnbuckles, also known as rigging screws, are critical hardware components used for tensioning and adjusting rigging systems. These products are classified and managed according to IMPA codes (e.g., IMPA 230678, 230548) and comply with international standards such as DIN 1480.

High-strength forged carbon steel (Hot-Dip Galvanized/Dacromet) or austenitic stainless steel (AISI 304/316L with Electropolishing).

End-fitting configurations include Hook & Hook, Eye & Eye, Jaw & Jaw, and combination ends for precise axial tensioning.

Randomly sampled proof load tests ensure that there is no permanent deformation under the Working Load Limit (WLL) and that the Minimum Breaking Load (MBL) meets the design safety factor of 4:1 to 6:1. Critical load-bearing areas are subjected to magnetic particle inspection (MPI) or dye penetrant inspection (DPI) to eliminate surface and near-surface cracks.
