These Fine Hex Adjuster Screws are great for miniature mounts. Manufactured to exact tolerances to ensure a smooth feel and excellent long-term stability, Thorlabs has developed a set of specifications that meet industry class 3 standards. All of our fine hex adjuster screws are made to these extremely tight tolerances and come lubricated to ensure smooth mating into compatible components. Each screw is individually tested with a master gauge set that ensures the inter-changeability of our adjuster screws and threaded sleeves.

 

6-80 Fine Hex Adjusters

* Four Lengths Available from 0.45" to 1.13"
* 0.1380" (3.5052 mm) Outer Diameter
* 5/64" Hex Key Compatible
* Max Load: 22.5 lbs (10.2 kg)

Our high precision 6-80 Fine Hex Adjusters can be adjusted with a 5/64" hex key, F6SSK1 removable adjustment knob (sold below), or HKTS-5/64 hex key adjuster knob (sold below). The F6SS series hex adjusters have a maximum load of 22.5 lbs (10.2 kg) to maintain smooth adjustments. They have an outer diameter of 0.1380" (3.5052 mm) and are shipped lubricated to ensure smooth mating into compatible components.

 

6-80 Removable Adjustment Knob

* Use with 6-80 Hex Adjusters
* Clearance Hole Allows Access to Hex Socket
* Knurled Knob Increases Adjustment Sensitivity

Our F6SSK1 removable adjustment knob threads on to our 6-80 F6SS series hex adjusters and allows a user to use the adjuster without a hex key. This provides quick and easy adjustments for a broad range of applications.

 

6-80 Threaded Bushings

* Ideal for Slip Fit Applications
* Two Lengths Available
* Made From 510 Phosphor Bronze (Vacuum Rated for 10-6 Torr)
* Recommended Bore Diameter: 0.225" +0.001/-0.000

Our 6-80 Threaded Bushings are commonly used in slip fit applications where fine adjusters are needed. Due to the tolerances of our fine adjusters, we discourage press fitting these bushings. The recommended bore diameter for our 6-80 bushings is 0.225" +0.001/-0.000. These busings are made of phosphor bronze, which offers advantages over brass, including vacuum compatibility. For vacuum applications, we recommend a thorough ultrasonic cleaning to remove any grease or particulates prior to use.

 

6-80 Lock Nut

* Knurled Outside Diameter for Easy Tightening
* Material: 510 Phosphor Bronze
* Vacuum Compatible: 10-6 Torr

The LN680 lock nut features a knurled outside diameter to make gripping the nut easier when loosening or tightening. The lock nut is made from 510 Phosphor Bronze, which is vacuum rated for 10-6 Torr. Each nut features blind holes that allow a hex key to be used to help tighten the lock nut.

 

5/64" and 2 mm Hex Key Adjusters

  • For Convenient Adjustment of 5/64" and 2 mm Hex-Driven Actuators
  • Red Anodized Adjustment Knob with Engraved Hex Size
  • Replaceable Hex Tip
  • Sold in Packages of 4

These 5/64" and 2 mm Hex Key Adjuster Thumbscrews allow for quick adjustment of many 5/64" (2 mm) hex-driven actuators (or standard actuators with the knobs removed). These temporary knobs can be left in the screw's hex socket between adjustments for convenience (see photo to the right). An 8-32 setscrew (5/64" hex) secures the replaceable hex bit, which can be reversed if the tip is stripped. 

We offer hex key thumbscrews in sizes from 0.050" to 3/16" and 2 mm to 5 mm.
