The BROWNELLS Thread Coating, Shock/Vibration Resistant, 30cc Bottle provides reliable fastener security for gunsmithing applications. Thread lockers like this are perfect for securing screws and fasteners, preventing them from loosening under recoil or during extended use. Understanding the proper use of threadlocker helps you avoid common gunsmithing mistakes that lead to loose parts, stripped threads, or difficult repairs, enabling you to build safer, more reliable firearms that hold up over time.
Vibration is the enemy of fasteners—on firearms, particularly semi-automatic platforms like the AR-15, screws and bolts are constantly under stress, and without the right treatment, they’re bound to back out over time. The 30cc size is ideal for frequent gunsmithing work and custom builds where you need consistent, professional-grade performance across multiple projects. Before applying this thread coating, it’s critical to clean and degrease the threads, as oil or debris can prevent the compound from curing properly—use denatured alcohol or a dedicated degreaser to prep the surfaces.
