- MISUMI offers the HFSM/HFSU series of flat tips clamping screws.
- The main body of the clamping ball screw is made of SCM435 equivalent material in the case of HFSM, and SUS304 equivalent material in the case of HFSU.
- The ball of the clamping screw is made of SUJ2 equivalent material for HFSM, and SUS440C equivalent material for HFSU.
- The screw is available in seven sizes: M4, M5, M6, M8, M10, M12, or M16.
- The screw is compatible with commercially available nuts that are equivalent to JIS6g.
- In the case of the Angle Type, a spherical hemisphere appears on the face due to its rotation instead of a flat plane.
