10 methods of anti-loosening safety bolts (1) thread locking glue
As a tool commonly used in fixtures, bolts are widely used, but long-term use will also bring many problems, such as loose connection, insufficient clamping force, and rusted bolts. During the processing and production of parts, the quality and efficiency of processing will be affected due to the loose connection of bolts. So how to prevent the bolt from loosening? Anti-loose purpose: to work more effectively for a long time; to improve the reliability of related workpieces.
Thread locking adhesive is an adhesive composed of (meth)acrylate, initiator, co-accelerator, stabilizer (inhibitor), dye and filler in a certain proportion.
For through-hole conditions: pass the bolt through the screw hole, apply thread locker to the thread of the mating part, assemble the nut and tighten to the specified torque.
For working conditions where the depth of the screw hole is greater than the length of the bolt: apply locking glue to the thread of the bolt, assemble and tighten to the specified torque.
For the stud bolt working condition: the locking glue should be dripped into the screw hole, and then apply the locking glue on the bolt, assemble the stud and tighten it to the specified torque; after assembling other parts, apply the locking glue to the stud Assemble the nut and tighten it to the specified torque at the meshing part with the nut; if the opening of the blind hole is downward, no glue is needed in the hole.
For pre-assembled threaded fasteners (such as adjustable screws): After assembling and tightening to the specified torque, drop the locking glue into the threaded joints and let the glue penetrate by itself.
