Commonly used in appliances, tools, machinery, furniture hardware, and general repairs, PrimeāLine socket set screws allow for precise positioning and strong holding power in tight spaces. Intended for use with sameāsize matching threaded holes and installed using standard hex keys, they offer easy adjustment and reliable performance. Manufactured from quality materials for durability and accurate threading, PrimeāLine socket set screws make it easy to achieve clean, secure, and professionalāgrade assemblies.
