Description
The Alfa Tools SI67523 5/16-24 NF Solid Thread Insert is a precision-machined, heavy-duty threaded bushing engineered to restore stripped or damaged threads or reinforce new ones in soft materials. Manufactured from high-strength, heat-treated steel and built to Unified National Fine (UNF) standards, this solid insert delivers superior pullout resistance, vibration resistance, and long-term durability. It installs permanently into a pre-tapped hole, creating strong, wear-resistant internal threads for bolts, studs, or fasteners in metal, wood, and plastic assemblies, making it ideal for repair, maintenance, and OEM manufacturing applications.
