Typical applications Automotive and machinery: stripped bolt holes in engine covers, brackets, or mounts to avoid part replacement. Furniture and fixtures: reinforce screw connections in wood, particleboard, or soft metals to reduce loosening and wear. Electronics and prototyping: add durable threaded inserts to 3Dprinted parts, enclosures, or chassis to accept repeated assembly.
