A Jam Nut (also known as a lock nut or thin nut) is a low-profile fastening nut used to lock another nut in place and prevent loosening due to vibration or movement. Perfect for machinery, automotive parts, industrial equipment, and heavy-duty assemblies, jam nuts provide reliable fastening where space is limited.
Manufactured with precision, our jam nuts deliver excellent grip strength, corrosion resistance, and long-term durability for all engineering and construction needs.
