3/8-16 SAE Thread Repair Kit, 0.52In One-Piece Inserts (10PCS)

Key features

• VERIFY THE SIZE BEFORE ORDERINGThis 3/8-16 UNC kit creates a finished 3/8-16 UNC internal thread with 0.520 in inserts. Match bolt diameter, pitch, insert length, usable hole depth, and wall thickness; the drill and outer tap dimensions differ from the finished internal thread
• USE THE MATCHED COMPONENTSIncludes 10 solid 304 stainless inserts, 1 HSS drill bit, 1 HSS tap, 1 counterbore tool, 1 installation driver, and 2 threadlockers. Use the supplied tools and inserts together; parts from other insert systems may not interchange
• Durable Solid Steel ConstructionUpgrade from flimsy 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
• CONTROL THE COUNTERBORE DEPTHThe counterbore creates the recessed seat that allows the insert to finish slightly below the mating surface. A shallow cut can leave the insert proud, while excessive depth can reduce support. A tap handle is not included; confirm tool access before work
• CHECK THE APPLICATION FIRSTIntended for stripped internal threads in suitable aluminum, cast iron, steel, and similar components with enough surrounding material and drilling access. Verify the repair requirements for engines, transmission housings, ATV/UTV components, motorcycles, and high-precision bicycle frames
• Pro TipApply threadlocker to screw threads before installation to prevent bushing from loosening during future removal. Over-counterboring may cause oil leakage. Check depth frequently during operation
