The Honda 90042-ZK2-D60 Stud Bolt (8X106) is a genuine OEM fastener designed for a range of Honda generators and horizontal shaft engines, including the EB3800, EB4000, EB5000, EB6500, EG4000, EM3800, EM4000, EM5000, EM6500, GX240, and GX270. As a factory-original component, this stud bolt is manufactured to the exact thread pitch, shank length, and dimensional tolerances specified by Honda. Confirm your unit's serial number against the fitment table before ordering, as Honda updates fastener specifications at production breaks.
Key Features
- Genuine OEM Fastener — sourced directly from Honda, so thread form, shank diameter, and overall length match the original specification exactly.
- Exact-Length Replacement — at 8 x 106 mm, this stud bolt is dimensioned to seat and clamp correctly without modification, maintaining proper clamping load in the assembly.
- Broad Compatibility — listed for Honda EB, EG, and EM generators as well as GX240 and GX270 horizontal shaft engines; check your serial number against the fitment table to confirm the correct application.
- Correct Hardware Matters — a stud bolt of the wrong length or thread can result in improper clamping, stripped threads, or assembly misalignment; using part number 90042-ZK2-D60 eliminates that risk.
A stud bolt is a fully threaded or partially threaded rod that is permanently anchored into one component at one end, with a nut fastened onto the exposed end to clamp a mating part in place. Unlike a standard bolt, a stud bolt stays in position during assembly and disassembly, making it easier to align covers, brackets, and housings without cross-threading. When a stud bolt is worn, bent, or stripped, it cannot apply consistent clamping force, which can allow joints to loosen under vibration and lead to oil or exhaust leaks, misaligned covers, or damaged mating threads.
