The Honda 72561-VF9-C11 LHF Shaft (10X1.25) is a genuine OEM component designed for HHT31, HHT35, UMK422, and UMK431 trimmers. As a direct Honda OEM part, it is manufactured to the same specifications as the original, ensuring a proper fit without guesswork. This shaft is the correct replacement for the left-hand thread, 10x1.25 mm specification — confirm your trimmer's serial number against the fitment table before ordering, as Honda supersedes parts at specific serial breaks.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this shaft meets the original design specification for thread pitch and dimensional accuracy critical to secure blade or attachment retention
- Left-Hand Thread, 10x1.25 Specification — the 10x1.25 thread designation is a key variant identifier; match it to your trimmer's existing hardware before installing
- Fits HHT31, HHT35, UMK422, and UMK431 Trimmers — confirmed fitment across these Honda trimmer models, including both the HHT and UMK series
- Serial Number Verification Recommended — Honda updates parts at production serial breaks, so cross-check your unit's serial number against the compatibility table to confirm this is the correct shaft for your machine
The LHF Shaft (10X1.25) is the output shaft on Honda trimmers that connects the powerhead to the cutting attachment. Its left-hand thread pattern is intentional — the rotational force of the trimmer head tightens rather than loosens the connection during operation, keeping the attachment securely in place. When this shaft is worn, damaged, or has compromised threads, the cutting attachment can become unstable or fail to seat correctly, affecting both cutting performance and operator control.
