Thorlabs' cap screw and setscrew kits are an essential part of any lab setup, especially when using optomechanical hardware. They provide a generous assortment of precisely machined screws, washers and nuts of different sizes within a conveniently organized storage box. Also available are screw kits specifically designed for use with our Mini-Series Construction Components. Screw kits are available in imperial or metric versions.

We also offer many of the cap screws and setscrews used in these kits in packages of 25 or 50, which are useful for refilling the more frequently used kit components. Click on the links in the tables below to see the corresponding package of 25 or 50 screws.

Please make a kit that contain screws with all the most common types of "inch" threads. It is not necessary with any tools, you sell separate tool kits already. I am sure a lot of European labs would appreciate such a product.

A response from Tyler at Thorlabs to melsscal: All of our balldriver sets contain the balldrivers needed for M4, M6, and M3. We have several options depending on your need. If you follow the Balldriver link near the top of the page, it will take you to a webpage with three options: TC3/M, BT17/M, and TC4/M.
