Alfa Tools 1/4-20 NC Solid Thread Insert

The Alfa Tools SI67505 1/4-20 NC Solid Thread Insert is a precision-machined, heavy-duty threaded bushing designed to repair stripped or damaged threads or to reinforce new threads in soft materials. Built from durable steel and engineered to ASME/ANSI thread standards, this solid-style insert restores internal threads to original strength or greater, providing superior holding power and vibration resistance. Ideal for maintenance, repair, and OEM applications, the SI67505 installs into a pre-tapped hole and delivers a permanent, wear-resistant thread for bolts, studs, and fasteners in metal, wood, or plastic assemblies.
