• 【Exact 5/16-18 SAE Thread Repair Kit】Specifically engineered for the 5/16-18 thread size, our 0.450 INCH long inserts perfectly restore stripped or worn threads in engines, auto parts, ATV/UTV parts, motorcycles, bicycles
• 【All-Inclusive, Ready-to-Use Kit】This complete set provides everything needed for a professional repair: 1 drill bit, 1 counterbore tool, 1 tap, 1 install driver, and 10 durable inserts (0.450 INCH length)
• 【Durable Solid Steel Construction】Forget weak wire coils. Our one-piece solid 304 stainless steel inserts provide a far more robust and permanent repair. They resist corrosion, prevent thread misalignment, and won’t unravel, offering a definitive solution for high-stress applications
• 【Precision Counterbore Tool】This specialized tool is engineered to cleanly machine a recessed lip at the top of the drilled hole. This cavity is crucial for properly seating the flange of the solid insert, ensuring it sits flush with or below the workpiece surface for a seamless and robust repair
• 【Permanently Repair Damaged Threads】Ideal for restoring ruined 5/16-18 female threads in aluminum, steel, plastic, iron, and other soft metals. The repair can be completed using an electric drill, a pneumatic drill, or entirely by hand. The process—drill, tap, and install the insert—is straightforward for anyone to follow
• 【Attention】Apply threadlocker to screw threads before installation to prevent bushing from backing out during future removal. Over-counterboring may cause oil leakage. Check depth frequently during operation
