Tension Control Bolts and the innovative Shear Wrench system are the lowest cost method of properly installing preloaded or High Strength Friction Grip (HSFG) bolts.

IKING, as they are commonly known, are replacing conventional high-strength friction grip bolts and swaged collar rivets simply because they are quick and easy to install using lightweight electric shear wrenches. Guaranteed tension together with visual inspection removes the likelihood of operator error and ensures that engineers that connections are tightened in accordance with specifications.

TC bolts Advantages

Technical

• Consistent tension
• Visual inspection
• Higher grade steel and increased pre-load facilitate the use of smaller diameter bolts
• TC bolts can be used in Shear and Tension
• No bolt relaxation since no torsional shear is induced during tightening
• Does not loosen with vibration – no locknut required
• Has a very hard surface and does not crack or flake

Cost Saving

• Quick, safe, and easy to install
• One-man installation
• Reduced tool maintenance
• One tool can install several diameters
• Tools do not self-destruct, so they last for many years
• Requires no further treatment, which means less time at the site

Safety

• Non-impacting electric shear wrenches
• No risk of HAVS (hand-arm vibration syndrome)
• Reduced operator fatigue
• No air compressors with dangerous pipes & cables
• Low on-site noise – under HSE minimum levels
• No heavy calibrated torque wrenches required
• Ultra-lightweight wrenches of varying shapes & sizes

About IKING

We’ve been working with contractors, fabricators, and distributors for years, and most improvements we make come directly from site feedback.

IKING focuses on producing arc weld studs and fastening solutions that actually perform in real working conditions — not just in theory.

FAQ

1. Why choose a weld stud bolt instead of traditional bolts?

Because it saves time and simplifies installation. No drilling or backside access is needed, and the connection is stronger.

2. Is an arc weld stud suitable for heavy-duty structures?

Yes, it’s widely used in steel structures and can handle high loads when properly installed.

3. What kind of materials can it be used on?

Mainly steel surfaces, especially medium to thick plates.

4. Do I need special equipment?

Yes, you’ll need an arc stud welding machine, but the process itself is straightforward.

5. How consistent is the welding quality?

Very consistent. Once parameters are set, each arc weld stud installation delivers similar results.

6. Can it reduce labor costs?

In most cases, yes. Faster installation means fewer labor hours and higher efficiency.
