In modern steel construction, achieving structural integrity and efficiency relies heavily on the quality and reliability of fastening solutions. Tension Control Bolts (TC Bolts) have emerged as a game-changer, offering superior accuracy, efficiency, and performance over traditional bolting methods. With LRKD Industries at the forefront of precision fastening solutions, TC Bolts are setting new industry standards for strength and ease of installation. This article explores the advantages, applications, and specifications of TC Bolts and how they enhance steel construction projects.

What Are Tension Control Bolts?

Tension Control Bolts are high-strength structural fasteners designed for pre-tensioned applications. Unlike conventional hex bolts, TC Bolts feature a built-in tensioning mechanism that ensures consistent and reliable tightening. The primary components of a TC Bolt system include:

Bolt: Featuring a splined end that controls tensioning.

Nut: Designed for secure engagement.

Washer: Ensures even load distribution.

Installation is simplified with an electric shear wrench, which twists off the bolt’s splined end upon reaching the required tension, ensuring accurate and repeatable preload.

Advantages of Tension Control Bolts

TC Bolts offer numerous benefits that make them the preferred choice for steel structures:

1. Precision & Consistency

Ensures uniform preload, reducing variability in bolt tension.

Eliminates guesswork, minimizing human error in installation.

2. Speed & Efficiency

Faster installation compared to traditional methods.

Requires only a single worker to operate the shear wrench, increasing productivity.

3. Improved Structural Integrity

Reduces the risk of bolt loosening under dynamic loads.

Enhances the overall durability of the connection.

4. Noise & Vibration Reduction

Generates less noise and vibration during installation compared to impact wrenches.

Ideal for projects with strict noise restrictions.
