LOCKBOLTS: HOW TO CHOOSE THE RIGHT ONE?
Friday, February 7, 2020
Clarify what they are and what they are for. Evaluate the technical characteristics and discover the advantages of using them.
What are lockbolts?
Lockbolts are a very quick fastening system, featuring high mechanical resistance for parts subject to strong vibrations.The quickness is given by the non-use of traditional fasteners (such as bolts with nuts), combined with ease of installation: no special skills are required.The system consists of a bolt and a collar and the fastening is given by the moulding of the collar on the locking lines of the bolt itself.
What are the main advantages and whe to use lockbolts?
The lockbolts are ideal to be used in several sectors: railway construction, motor vehicles, ventilation, metal structural works, shipbuilding, and particularly in those applications where disassembly is not required.The grooves around the bolt diameter ensure excellent resistance to vibrations, considerable tolerance in the grip range of the parts to be fixed, installation speed, high shear and tensile strength.The main advantages of the lockbolt system are:
• Reduction in assembly time
• Steady mechanical features
• Easy installation and check
• Noiseless operations
RIVLOCK
Standard lockbolts available in either zinc plated steel, aluminum or stainless steel, with dome or countersunk head, and in diameters 4.8 – 6.4 – 8.0 – 10.0mm.
RIVLOCKGRIP
These are lockbolts ideal when a higher grip range is required to satisfy different work needs. They are available in steel and aluminum, dome or countersunk head, and in diameters 4.8 and 6.4 mm.
RIVTAINERS
They are bolts suitable for fastenings on rigid/soft surfaces because they have a minimum protrusion both internally and externally. These type of bolts are particularly suitable for the construction of vehicles and containers and for the assembly and fixing of plywood and similar materials. They are available in zinc plated steel, with dome head, diameter 9.5 mm. In addition to the lockbolts, the related collars are available according to the material chosen.
