The ATC-8707 / PT-8707 Detroit Diesel 60 Series Bolt Hole Thread Insert is a precision repair component designed to restore damaged or compromised head bolt holes in Detroit Diesel 60 Series (DD13, DD15, DD16) engine blocks. This insert features an internal thread size of M16 × 2.00 and an external thread dimension of 13/16"-16 TPI, with an overall length of 2.50", providing strong engagement and reliable thread restoration.
When original head bolt threads become stripped, worn, or out of tolerance, installing the ATC-8707 insert restores proper bolt engagement, alignment, and clamping strength. This repair solution allows technicians to restore block integrity without expensive machining or block replacement, making it ideal for diesel engine rebuilders, repair facilities, and remanufacturing operations.
