Transition Fit Spec Table
Transition Fit KS Specifications — 4 sizes
KS B 0401
A transition fit that may result in either clearance or interference depending on actual dimensions, used where positioning with disassembly capability is needed.
Practical Notes
- H7/k6 is the standard locating fit. Assembled by rubber mallet or hand press; disassembly is possible.
- Actual fit may be clearance or interference depending on dimensions. Measure parts before assembly.
Selection Guide
Transition zone where either clearance or interference may occur. Common fits: H7/k6 (locating), H7/js6 (slight interference), H7/n6 (light press). For disassemblable precision positioning. Assembled by hand press or rubber mallet.

FAQ
Difference between H7/k6 and H7/js6?
H7/k6 is standard "locating" fit with slight interference. H7/js6 is "transitional" with nearly equal chance of clearance or interference — slightly easier assembly than k6.
