Product Description
- Titanium alloy mounting screws included.
- The 316L Stainless Steel body is subjected to special demagnetization treatment after processing.
- Overall relative permeability: outer plane <1.05, holes and curved surfaces <1.08
- Multiple lengths available
- Top M4 Thread, bottom M6 Thread
The LBTEK NMMT Series Weakly Magnetic Mounting Posts feature an M4 Thread at the top and an M6 Thread at the bottom, both with Ø2 mm Alignment Holes for aligning Optic Mounts.
The body of the NMMT Series is made of 316L Stainless Steel. After machining, it undergoes a special treatment that fully restores the magnetic martensite generated during machining into a Non-Magnetic austenitic structure. This process allows it to inherit the excellent Thermal Stability of 316L Stainless Steel with its low Coefficient of Thermal Expansion, while ensuring extremely low relative magnetic permeability for the entire assembly (outer planes <1.05, holes and curved surfaces <1.08). In addition, all accessories are made of weakly magnetic or even Non-Magnetic materials.
LBTEK also provides customization services for special surface treatment processes, lengths, and dimensions. If you have special requirements, please contact LBTEK technical support.

- Includes one M4 titanium alloy cup point set screw
LBTEK NMMT Series Weak Magnetic Posts are made of 316L stainless steel and specially treated to fully restore the magnetic martensite generated during machining to a non-magnetic austenitic structure. Each post has an M4 thread at the top and an M6 thread at the bottom, both with Ø2 mm alignment holes for positioning Optic Mounts. There is an alignment hole 20 mm from the bottom M6 threaded side, which can be used with MOP Series coaxial posts to align multiple mounts along the optical axis. Different lengths are available; currently, five lengths are offered: 25 mm, 38 mm, 50 mm, 75 mm, and 100 mm posts.
