Tension Control Bolts
High-Performance Tension Control Bolts for Secure Fastening
Tension control bolts, also known as TC bolts, are specialized fasteners designed for critical connections in steel construction applications. These bolts are sold in designated assemblies constructed by the manufacturers that
must be used together
and are engineered to provide a precise level of tension when installed. Each assembly comprises a bolt, a nut, a washer, and a splined end that snaps off when the correct tension is achieved with a specific calibrated tension control tool. The bolts come in various diameters and lengths to accommodate diverse structural requirements for steel frame construction, bridge connections, and heavy equipment assembly.
The primary function of tension control bolts is to maintain structural integrity in heavy-duty applications by providing a controlled, uniform preload. This preload helps to distribute the load evenly across the connection and minimize the risk of bolt fatigue and failure. The innovative design of TC bolts allows for installation from one side of the application with only one person running the tension control tool. This significantly reduces labor time and costs, while the built-in tension indicator provides assurance of proper installation.
- Controlled Tensioning: The bolt, when used properly with the pre-calibrated installation tool, is designed to ensure consistent preload and joint stability.
- Standardized Materials: All TC bolts are available in either ASTM F3125, Grade A325 or A490, steel with special coating that should not be tampered with – they are designed to facilitate safe and optimal performance; tampering will affect the bolt’s holding power and corrosion resistance.
- Precise Design: These fasteners are heavily regulated by standards; the manufacturers ensure proper conformance in the design stages, so the bolt assemblies can and should be used as-is from the manufacturer. Do not use an assembly that has been removed from its original packaging before installation.

Importance of Correct Tension Control Bolt Installation
Since tension control bolts are an integral part of structural applications, it’s essential to follow the manufacturer’s directions for proper installation. The bolts are specifically assembled with nuts and washers and coated in lubrication to aid the standardized process, so it’s important you do not tamper with the assembly or remove it from packaging before use; this can degrade the bolt’s integrity and cause a faulty connection. When it comes to installation, ensure the bolt meets the designated tension requirements and is snugly attached to the mating material before using the tool to tighten it.
