Thumb screws are designed to be tightened and loosened by hand. They come in a variety of head styles, but each includes an easy-grip head which allows for simple "by-hand" installation.Nylon 6/6 is a general purpose thermoplastic with outstanding resistance to organic chemicals, acids and alkalis. Nylon wears well against other surfaces; it is readily machinable and may be milled, turned and cut with conventional machine tools. It does exhibit some dimensional swelling in wet applications which should be taken into account with its use. Tensile strength of this material is 12,000 psi (pounds per square inch).Usually found on thumb screws, a knurled surface on the head gives a better gripping surface, making it easier to tighten or loosen fasteners manually. Common applications for slotted screws include woodworking, although the drive style is not designed to be used with power drivers. A threaded fastener's size name includes information about the major external diameter, followed by the threads per inch, which indicates if it is coarse or fine. Coarse threads are better when working with brittle materials; they are sturdier and are easier to thread and unthread compared to fine. Coarse threading also allows for thicker coatings and platings.

Nylon 6/6 is suitable where non-conductivity, corrosion resistance, and cost are important considerations
Knurled head provides extra grip for manual tightening
Driven by a flat-bladed driver
Coarse threads are better for brittle materials, and will assemble and disassemble more quickly than fine threads
Nothing like a good screw. These fasteners have a nice head and you can twirl them by hand if you want. They are fairly strong and the tips are tapered so you can twist the nuts on them without cross-threading. I would prefer a Phillips head to the slotted head so I could use a power screwdriver with them. Good price on these too.These screws are not 1/4 inch as advertised. My application is a precision device and requires exactly .250 inch screws. These parts are .231 or .019 short. Unless you don't care about losing .019 inches they are just OK. I don't like the grip of these, however.They are not nearly as good as the older design that had a double gripping surface. Unfortunately it seems the good designed thumbscrew of yesterday is gone in 1/4 inch. They are much harder to turn and just don't feel like a good thumbscrew. I will keep searching for the better screws, as these things just don't work in my product. Very disappointed in this part.Exactly what I wanted, hard to find 10-24 thread with this style of screw head for a Celestron finder telescope.Fast shipping - product exactly as advertisedWhat arrived at my home is exactly what I wanted. The picture is not the right one. These little screws look like nylon versions of thumb screws on a computer case - which is what I wanted. You get plenty of them at a cheap price. Speedy delivery.I ordered several nylon items and all of them are as described.The Nylon 6/6 Thumb Screw I ordered fit perfectly with the Nylon 6/6 Small Pattern Machine Screw Hex Nuts.What more can you ask?Filled its purpose. Arrived on time and order was as described online.I received these nylon thumbscrews quikly and exactly as described. They are extremely useful for me and difficult to find. Many thanks
