Threaded Rod Full Thread Bar Stud

Unlike conventional bolts and stud bolts which have fixed lengths and restrictions on the exposed rod sections, the Threaded Rod Full Thread Bar Stud produced by Wanluo manufacturer adopts an all-thread structure without heads or tails, with no blank exposed rod sections throughout the entire rod. It maintains a continuous and complete thread layout throughout the entire process, allowing for on-site arbitrary cutting, secondary processing, and personalized fixed-length adaptation. It can perfectly solve the engineering pain points of limited length of traditional fasteners, inability to adapt to extremely long spans, and difficulty in continuous fixation. It is widely used in scenarios such as tensioning fixation of large equipment, connection of building structures, auxiliary locking points of work tools, overall assembly of electromechanical equipment, etc. At the same time, it supports ready-made full specifications for stock preparation and batch customization cutting for engineering, and is suitable for various large and medium-sized project centralized procurement requirements.

Material Advantages

The Threaded Rod Full Thread Bar Stud is made from high-quality solid round steel of stainless steel as the base material. It is precisely processed through multiple steps of precision threading, straightening, and acid washing and passivation. Through professional metallographic structure stabilization treatment, the rod body has high straightness, uniform and regular thread arrangement, precise control of thread pitch tolerance, and can be seamlessly matched with various standard nuts and connecting parts. The surface is free of burrs, oxide scale, and impurity flaws. The overall mechanical performance is stable. After cutting, secondary processing, and repeated disassembly, it can still maintain stable locking accuracy and structural strength. It is a highly versatile basic threaded profile widely used in industrial engineering.

Actual performance tests

1. Straightness and cutting accuracy test

Randomly inspect the entire length of the long rod for full segment straightening inspection. The rod body has no bending or curvature deviation, and the overall straightness meets the DIN975 industrial tolerance standard. After cutting the screw rod in multiple segments arbitrarily, the cutting ports have no tooth breakage, deformation, or skewing. Each segment of the split thread still maintains uniform engagement accuracy, and the secondary processing adaptability is excellent.

2. Tensile strength and structural toughness test

Through the universal tensile testing machine, conduct gradient tension testing. The overall force of the screw rod is uniform, without local fracture or plastic deformation problems, and the ultimate tensile load meets the standard. After continuous static tension and repeated unloading tests, the structure of the rod body has no fatigue damage, and the threads have no stretching tooth loss. It can withstand the tension of the equipment and the static negative load of the structure for a long time.

3. Thread matching and engagement test

With the same specification national standard and German standard nuts, conduct reciprocating rotation and engagement test. The entire thread insertion is smooth without jamming, no slack, and no stuck. The tooth shape is closely fitted. After multiple repeated disassembly and assembly, the thread wear is minimal, and the engagement accuracy has no significant attenuation. It is suitable for high-frequency debugging and repeated assembly scenarios.

4. Surface anti-corrosion and weather resistance test

Our Threaded Rod Full Thread Bar Stud has undergone complete surface treatment of acid washing and passivation. It is subjected to durability tests in simulated outdoor humid, salt fog, and normal temperature oxidation environments. The surface of the rod body is not prone to oxidation, peeling, rusting, or corrosion. It does not accumulate impurities for a long time and can maintain a smooth appearance and stable thread accuracy, suitable for outdoor engineering and damp workshop conditions.

5. Overall structural stability test

For the installation condition of long rods suspended and spanning for continuous installation, conduct a simulated load-bearing test. The screw rod has excellent resistance to bending and deformation. After multiple points of locking, there is no deflection. The overall structural bearing capacity is uniform and can meet the safety standards for large-scale structural continuous tensioning and auxiliary fixation.

Production Process & Tolerance Control

This full thread rod adopts high-quality stainless steel solid round steel as raw material, processed through multi-pass precision thread rolling and straightening calibration technology. The whole rod body achieves continuous uniform thread distribution with consistent tooth pitch and precise tolerance, ensuring seamless matching with standard nuts. Strict surface pickling and passivation treatment eliminates burrs, oxide scales and impurities, presenting a smooth and tidy rod surface. The integral forming process stabilizes the internal metal structure, enabling excellent straightness, tensile strength and anti-fatigue performance. It can maintain stable fastening accuracy after arbitrary cutting, secondary processing and repeated assembly.

Product Parameter

Product Advantages

1. The entire rod is designed with full teeth, offering unlimited length usage.

The entire rod has continuous threads throughout, without any blank sections of the smooth rod. It breaks the limitation of fixed length for traditional bolt fixation, allowing for free cutting to adapt to non-standard sizes based on the on-site conditions. It perfectly meets the assembly requirements for ultra-long spans, irregular structures, and customized points, with extremely high flexibility in engineering adaptation.

2. The precise rolling tooth process has extremely strong versatility.

Multiple layers of precise rolling tooth forming result in full tooth profiles, uniform pitch, and precise tolerances. It is compatible with global standard nuts and matching fasteners, ensuring uniform mating gap, smooth rotation, and eliminating issues such as mismatched specifications, assembly jams, and lock-up gaps.

3. Balanced mechanical performance, strong anti-fatigue load-bearing capacity.

The base material undergoes structural optimization and overall molding treatment, with dense and uniform internal metal structure, high straightness, and excellent tensile strength. It can withstand static loading, slight vibrations, and structural tension for a long time, remaining less prone to deformation and fatigue fracture, and having a longer service life.

4. Excellent surface processing, corrosion-resistant and easy to maintain.

The Threaded Rod Full Thread Bar Stud undergoes professional acid washing and passivation treatment, thoroughly removing processing residues, oxide layers, and surface impurities, resulting in high overall glossiness. The stainless steel base material combined with high-quality surface processing has outstanding rust and corrosion resistance, suitable for various complex outdoor and indoor working conditions, and simple post-maintenance.

5. High engineering adaptability, supporting batch customization.

Full-size specifications are available in stock, and also support engineering customization cutting, precision processing, which can meet the needs of small-batch component replacement and large-scale project centralized procurement, effectively reducing engineering inventory costs and shortening construction cycles.
