On list here is a set of 3 used but in good functioning conditions Newport AJS100-0.5H hex adjustment screws.

The AJS100-0.5H Adjustment Screw has precision rolled threads for exceptionally smooth adjustment and higher sensitivity than standard micrometers. The AJS100-0.5H offers 0.5 inch (12.7 mm) precision travel obtained with hex-head adjustment, ideal for use with Newport optical mounts, stages, and most micrometer-compatible components. With sub-micron sensitivity, they are a cost-effective alternative to micrometers where position readout is not required.

The pricing is for one set of three units shown in photos. Newport currently sells a brand new unit for $40 or the set for $120 in 2026.

14-day return is allowed on functional defects with buyer to pay for return shipping. Cosmetic and non-functional related return may be subject to 15% restocking charge. Domestic shipping only with the disclosed shipping cost. Cost for International shipping where shippable may vary and please ask before committing to buy. No pay bidder will be reported. CA in-state shopper needs to pay 10.75% or waive the tax by a valid Resale Permit for resale purpose. I do give feedback comments after receiving feedback from my customers and often in good and reciprocal terms. Before any purchase, a buyer first agrees to not leave a negative feedback without contacting me to try to resolve any issue. I do respond promptly and I am customer and service oriented.
