High Strength Tension Control Bolts
Surface treatment: Oxidation and blackening
Color:Black/Zinc coated
Product features: wear-resistant
Product Description
High strength tension control bolts are specialized bolts used to connect structural members, often in engineering projects that require high strength and reliability. These bolts are designed to hold connected parts tight by applying a predetermined tension, rather than tightening with torque. They usually consist of two parts: the bolt itself and a nut that controls the tension.

Feature
The tightening method of torsion-shear type high-strength bolts is simple and easy to check. It only requires a TC-type electric wrench, which is often used in building structures.
This type of bolt usually consists of a threaded rod and a nut, and its internal structure contains a torsional shear zone. When stretched, the torsional shear zone undergoes special deformation, which results in higher strength and better reliability. This design can effectively avoid loosening or cracking during use, thus ensuring the safety of the equipment.
At the same time, torsion-shear type high-strength bolts also have vibration resistance and fatigue resistance, which is an important reason why they are widely used.
Bolt connecting for steel structure is a connection method that uses bolts to connect two or more steel structure parts or components into one body. Bolt connection is the simplest connection method in component preassembly and structural installation.

Tension control bolt(T.C.bolt) features in steel structure
T.C. bolts are crucial in keeping the various components of steel buildings together.
These bolts are perfect for heavy-duty applications because of their remarkable resistance to tensile and shear pressures.
2.High strength steel structure T.C. bolts are notable for having a high strength.
They are constructed with durable materials and go through rigorous quality inspections to make sure they adhere to all applicable safety regulations. They thus provide a dependable and long-lasting way to fasten steel constructions.
3.T.C bolts are made to be quick and simple to install as well. They fit precisely into pre-drilled holes thanks to a straightforward yet incredibly effective threading method. In addition, its tapered design guarantees a tight fit, which improves their resistance to shock and vibration.
4.High strength Torsion Shear Bolts are resistant to corrosion.
Typically, they are coated with compounds to prevent rust and other types of corrosion, such as zinc or galvanized steel. This lessens the need for regular maintenance and helps the steel structure last longer.
T.C. bolts are a great aspect of steel buildings, to sum up.
They are an essential part of the construction industry because of their great strength, simplicity of installation, and resistance to corrosion. They provide a dependable and long-lasting means of fastening steel buildings, guaranteeing their strength and durability for many years to come.
