EziTite® Hydraulic Bolts
EziTite® Hydraulic Bolts: Precision Hydraulic Fasteners for Heavy Industry
EziTite® Hydraulic Bolts are precision-engineered, high-performance, hydraulically operated fasteners that incorporate advanced mechanisms for direct bolt tensioning. These specialised fasteners minimise the time required to execute critical bolting procedures while delivering extreme resistance to vibration and shock loads. Manufactured from high-grade alloy or stainless steels to meet exact application requirements, they can be rapidly fitted and pressurised using standard pumping equipment, including Technofast hand-operated, electric-hydraulic, or air-hydraulic pumps.
What Are EziTite® Hydraulic Bolts?
Standard torque tightening relies on friction, which can lead to inaccurate joint loading. In contrast, EziTite® Hydraulic Bolts utilise direct hydraulic pressure to eliminate friction guesswork entirely. These high-tensile fasteners feature a unique lockring thread technology that mechanically secures the stretched bolt, ensuring maximum retained load across critical joints. To accommodate complex industrial operating environments, they are available with optional protective covers, specialised surface treatments, and custom-designed seal profiles to match distinct temperature and pressure profiles.
Tool Features:
-
- Diameter Range: Available in standard sizes from 20mm (7/8”) up to 100mm (4”) bolt diameters
- Lockring Thread: Uses mechanical thread technology to secure and lock the retained load
- Spherical Washer: Supplied as standard to ensure proper alignment with the joint face
- Standard Fittings: Pre-fitted with CEJN-type male snap fittings and 1/8″ BSPP porting
- Pressure Capacity: Rated up to a maximum pressure of 100 MPa for standard models
- Stroke Indicator: Built-in visual indicator to monitor bolt elongation during tensioning
- Bleed Plugs: Integrated into the assembly for safe, controlled pressure release
- Material Options: Manufactured from alloy or stainless steels based on application demands
Benefits:
-
- Vibration Resistance: Eliminates fastening failure on machinery subjected to heavy shock loads
- Frictionless Loading: Removes the torque-loss guesswork by stretching the bolt axially
- Time Savings: Minimises labor hours required to secure or open critical industrial joints
- Confined Access: Enables reliable tightening in tight, restricted, or awkward physical locations
- Repeatable Maintenance: Simplifies regular inspections where repeated adjustments are required
- Custom Engineering: Scalable beyond standard limits for unique temperature or pressure needs
- Pump Compatibility: Operates seamlessly with standard hand, electric, or air-hydraulic pumps.
Ideal for:
-
- Precise Pre-loading: Ideal when highly accurate and reliable loading is required on bolting assemblies
- Stress Management: Engineered for joints where severe vibrational or torsional stresses pose a problem
- Repeated Access: Maximises efficiency where regular maintenance requires repeated adjustment or removal of fasteners
- Restricted Access: Built specifically for environments where fasteners may be in confined or difficult locations
- Heavy Processing Machinery: Highly suited for securing vibrating screens and sieves
- High-Pressure Containment: Purpose-built for critical piping flanges, reactor joints, and vessel covers
- Heavy Infrastructure: Perfectly configured for anchoring autoclaves and structural foundation bolts.

FAQs
The standard manufactured range for these precision fasteners spans from 20mm (7/8”) up to 100mm (4”) bolt diameters. Custom sizing outside these standard parameters can be engineered to suit specific project requirements.
They are fully compatible with standard hydraulic pumping equipment. This includes Technofast hand-operated options (such as the PU-HP1800CJ Hand Pump), as well as electric-hydraulic or air-hydraulic pump units.
Standard EziTite® hydraulic bolts operate up to a maximum pressure of 100 MPa. For applications with higher pressure thresholds, custom designs can be configured.
Yes. Technofast provides full custom design, engineering, and manufacturing services. This allows bolt lengths, materials, and seal profiles to be tailored to unique operational temperatures and pressures.
This technology is primarily utilised in heavy industries prone to high operational stress, including mining, oil & gas, wind turbine power generation, steel mills, sugar mills, and quarries.
