Sign Fixing Clamps
Tamtorque® Sign Fixing Clamps
Engineered for demanding infrastructure environments, Tamtorque® sign fixing clamps deliver exceptional strength, tamper resistance and long-term reliability for sign installation, street furniture and mounted equipment. Designed for secure fastening to round, octagonal and irregular post profiles, these clamps provide consistent performance across highways, industrial sites and public realm installations.
Manufactured from high strength stainless steel (BS304 – EN 1.4301) with a hardened tamper-resistant screw (BS410 – EN 1.4006, heat treated to 1220 N/mm²), Tamtorque clamps are built for applications where safety, durability and resistance to vandalism are critical.
Technical Performance & Features
Vandal Resistant
Tamtorque clamps incorporate a unique recessed seven-sided socket screw, which can only be tightened or released using the dedicated Tamtorque tool. This tamper-resistant design prevents unauthorised removal and withstands persistent attack, making them ideal for exposed public areas or sensitive security installations.
High Strength Under Load
Using the proven Hi-Torque inline housing design, Tamtorque banding delivers performance levels far exceeding conventional sign fix bands. Real-world pull tests show that Tamtorque clamps withstand over 1.5 tonnes of tensile force, ensuring structural integrity for large signage in high wind zones or vibration-heavy environments.
Weather, Corrosion & Fatigue Resistance
Constructed from stainless steel throughout, including the housing and buckle, Tamtorque clamps offer excellent resistance to:
-
Corrosion
-
UV exposure
-
Temperature fluctuations
-
Vibration and mechanical fatigue
This makes them suitable for long-term external use with minimal maintenance requirements.
User Friendly & Installer Focused
Designed to make installation efficient and safe on site, Tamtorque clamps feature a patented auto-locking safety buckle which keeps the free end of the band secure and tidy. Installers benefit from:
-
Fast, controlled tightening
-
Clean, safe handling
-
Consistent tension across installations
-
Reduced risk of edges or protrusions after fitting
Reusable & Adjustable
- Unlike many sign fixing systems, Tamtorque clamps can be fully loosened, repositioned or removed using the dedicated tool.
- Cost-effective solution for contractors managing temporary installations, signage changes or maintenance cycles.
Applications
Tamtorque fixing clamps and sign fixing systems are widely used by local authorities, utility providers, contractors and installers across the UK. Typical applications include:
-
Road and traffic signage
-
Directional and regulatory street signage
-
Street lighting columns
-
Public information displays and notice boards
-
CCTV cameras and security systems
-
PA systems, sensors and electronic equipment
-
Commercial and industrial signage
-
Street furniture mounting
Their strength and tamper resistance make them particularly suited to high-risk or high-exposure locations including motorways, pedestrian areas, rail environments and urban infrastructure.
