The small diameter Lockbolt pin and collar is a two-piece fastening system. Lockbolts offer a high strength, vibration proof installation and high shear and clamp loads.
Lockbolts are quick and easy to install, tamper proof, and offering a wide range of diameters and lengths make them the ideal choice for engineering applications and general fabrications.
Ø 4.8mm (3/16”)
Ø 6.4mm (1/4”)
Ø 8.0mm (5/16”)
Ø 9.6mm (3/8”)
Standard Head Styles: Brazier head, Truss Head, CSK
Material / Finish: Steel, Aluminium, Stainless Steel
Optional Finish: Industry standard finishes available.
Optional Very High Tensile Strength: 10.9 grade
Optional Head or Styles: Custom made bolts and head styles can be developed for customers with specific applications. Typically used where the outer head of the lock bolts can perform additional functions designed into the manufacture.
Once the collar has been swaged onto the Lockbolt a permanent vibration proof joint is achieved.
The pre-load values remain consistent on every installation.
Our Lockbolt fasteners have been extensively tested and conform to the very same specification as industry standards.
It is important to note that both our fasteners and tooling are fully compatible and above all interchangeable with industry standard systems.
The design and construction of the Lockbolt fastening system ensures the user of a high pull together of joints and permanent clamp force with consistent pre-load on every fastener.
The high tensile and shear strength of the installed Lockbolt provides a joint with very high resistance to vibratory loosening. This ensures that all fasteners are installed with the same results under all conditions.
Visual inspection of the installed fasteners eliminates the need for expensive equipment and time consuming inspection methods.
- The pin is inserted into the pre-cut hole
- The collar is placed over the pin
- Tool is covers the pin tail and activated
- Tool swages collar and creates clamp
- Pin tail breaks and installation is complete
