Brass Thumb Screw, Knurled Head, 1" Length, Fully Threaded, 1/4"-20 UNC Threads, Made in US (Pack of 5)
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 that allows for simple "by-hand" installation. The thumb screw has a diamond knurled surface on its head. This gives it better gripping surface, making it easier to tighten or loosen the fastener manually.
Free-machining brass, also known as alloy 360, is the most commonly used brass alloy. It resists corrosion and is nonmagnetic. Combined with a precision-machined finish, it also offers a decorative gold color for a finished look.
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.
