lockbolt fasteners supply
Lockbolt fasteners are a high-strength mechanical locking fastening system consisting of a locking nail (bolt) and a locking ring (collar). Lockbolt fasteners are installed with a special tool that presses the collars into the annular grooves of the lockbolt to achieve a permanent mechanical fit. Compared to conventional bolts or blind rivets, Lockbolt construction requires no threading or torque control, resulting in a stronger connection that will not come loose due to vibration, making it particularly suitable for load-bearing structures and long periods of dynamic loading.
Widely used in railroad vehicles, heavy trucks, construction machinery, lifting equipment, mining equipment and wind turbine towers, the fastening system offers an efficient, consistent and low-maintenance installation process. Due to its excellent shear, tensile and anti-loosening properties, Lockbolt has become one of the most reliable alternatives to welded and bolted connections.

Applications of Lockbolt Rivet Fasteners
Lockbolt fastener is ideal for a wide range of medium and heavy structural connections due to its extremely high mechanical strength, vibration resistance and anti-loosening properties.
HVAC Systems
The lockbolt fastener on the HAVC includes fan housing fixing, bracket attachment, air guide plate construction, evaporator/condenser assembly, and support base fixing.
Trailers & Containers
lockbolt rivets can provide extremely high shear strength and fatigue life, and can withstand long-distance transportation vibration and deformation stress. Therefore, they are used in a large number of container bottom beams, corner posts, side panel reinforcement, trailer frames, trailer connecting beams, and aluminum skeleton assemblies.
Rotating Equipment
Lockbolt will not loosen due to vibration and centrifugal force during equipment operation, and is far superior to traditional nutted joints. It can be found on motor housings, gearboxes, fan mounting frames, pump support bases, and bearing structure joints.
Retail Equipment / Carts
Shopping cart skeleton, storage shelf support points, automatic shelf roller structure, mobile base connection.
Rail & Transportation
Train carriage skeleton, bogie, door body connection, high-speed train interior frame, wagon structural beams, body shell splicing and repair replacement structure.
Heavy-Duty Infrastructure
Lockbolt provides long term load carrying capacity and is not subject to loosening from wind loads and temperature variations. Therefore, communication towers, solar racks, signal lamp support arms, bridge steel nodes, scaffolding joints, and steel platform fixing are all used.
