Spanner Wrenches for Mini-Series Fixed Optic Mounts

These spanner wrenches are designed to install or adjust the retaining rings included with our Mini-Series Fixed Optic Mounts. The hollow construction of each spanner wrench allows the retaining ring to be adjusted without obscuring the beam path. They feature knurled handles for improved grip as well as guide flanges that prevent most optical surfaces from being scratched while the wrench is inserted. The table below details which Mini-Series fixed optic mount or retaining ring is compatible with each spanner wrench.

Adjustable Spanner Wrench

  • Diameter Range from 0.12" to 2.89" (3.0 mm to 73.4 mm)
  • Self-Centering, One-Handed Diameter Adjustment Mechanism
  • Replaceable Stainless Steel Blades

Thorlabs' Adjustable Spanner Wrench features a spanning range that is continuously adjustable from 0.12" to 2.89" (3.0 mm to 73.4 mm). It is capable of providing an exact fit for retaining rings as large as the SM3RR for Ø3" Lens Tubes and Mounts. The diameter spanned by the blades remains centered while the knurled knob is adjusted.

The reversible blades have a flat tip on one end intended for use with retaining rings, and an edge-offset fine point on the opposing end for adapters with holes. The blades extend 1.6" (40.7 mm) from the body of the wrench. Hence, compared to our cylindrical spanner wrenches sold above, the SPW801 is ideal for securing lenses with a high radius of curvature because the guide flanges on the cylindrical spanner wrenches may come into contact with the lens. To reverse the blades, a 0.050" (1.3 mm) balldriver or hex key is needed. Replacement blade pairs are available separately.

The SPW801 wrench withstands a maximum torque of 80 inch-pounds (9 N·m).
