Lock Shear Bolt

Lock Shear Bolt

Description

A Lock Shear Bolt is a high-security mechanical fastener designed to offer tamper-proof, vibration-resistant, and reliable locking. These bolts are engineered with a break-away hex head that shears off at a predetermined torque, leaving behind a smooth, conical surface that cannot be removed without special tools. Commonly used in rebar couplers, structural joints, and security installations, they ensure permanent locking where re-tightening or removal is not desired.

Applications and Benefits

Applications:

• Rebar coupler locking systems
• Infrastructure safety components
• Security fencing and barricades
• Signboards, poles, and utility structures
• Railway and metro structures

Benefits:

• Provides tamper-proof locking after installation
• Ensures consistent torque without overtightening
• Ideal for permanent or high-security connections
• No need for special torque tools – breaks automatically
• Improves assembly safety and integrity

Key Features

• Made from high-tensile carbon or alloy steel
  
• Shear-off hex head design for one-time tightening
  
• Anti-corrosive surface coating (zinc, galvanised, etc.)
• Torque-controlled breakaway mechanism
  
• Smooth finish post-shear for safety and security
  

Where It’s Used

• Rebar mechanical coupler locking
  
• Heavy-duty construction joints
  
• Urban infrastructure fencing
  
• Industrial and electrical panel fixings
  
• Railways and power transmission poles

Uses

• To secure rebar couplers permanently
  
• To provide a tamper-proof assembly in public areas
  
• To maintain alignment and hold under dynamic loads
• To eliminate the need for torque wrenches or supervision
  
• To enhance safety in joints exposed to vibrations or movement
  

Importance and Significance

Lock Shear Bolts are crucial in scenarios where security, permanence, and integrity of joints are non-negotiable. Their shear-off design ensures the bolt cannot be tampered with after installation. In rebar couplers, they provide consistent clamping force, especially in structural zones exposed to stress and movement. Their importance continues to rise with increasing demands for anti-theft, anti-loosening, and high-performance fastening solutions.

FAQs

1. What is a lock shear bolt?

   It is a fastener that locks in place by shearing off its head at a preset torque, making it tamper-proof.

2. Where is it used?

   Commonly used in rebar couplers, infrastructure fencing, and tamper-proof applications.

3. Does it need a torque wrench?

   No. It automatically shears at the required torque during installation.

4. Can the bolt be removed?

   No. Once sheared, it cannot be removed without damaging the assembly.

5. Is it rustproof?

   Yes, it is coated with corrosion-resistant finishes like zinc or galvanization.

6. Is it reusable?

   No. Lock shear bolts are single-use fasteners.

7. Do you supply in bulk?

   Yes, bulk orders are supported for construction and industrial use.

8. Are they available in different sizes?

   Yes, we offer various sizes to fit multiple coupler and bolt applications.
