STUD BOLTS

Stud Bolts are fasteners designed to withstand high tensile stresses. They find use in support structures, industrial plants and anchoring systems, providing strength and stability even under the most extreme conditions.
THREADED RODS

Threaded rods are cylindrical elements threaded along their entire length, ideal for applications requiring flexible adjustments in fastening. They can be cut to size and used in industries such as construction, plant engineering and advanced mechanics.
THREADED STUDS

Threaded Studs are fasteners that have a thread on both ends, designed to provide strong and secure connections between multiple components. They are used in mechanical and structural applications where high load resistance is required.
ANCHOR BOLTS

Anchor Bolts are used for anchoring metal structures, machinery and industrial plants. Their geometry, with a threaded part and a shaped end for insertion into concrete or base structures, ensures stable and durable fastening.
