The Unified Thread Standard (UTS) defines a standard thread form and series—along with allowances, tolerances, and designations—for screw threads commonly used in the United States and Canada. It is the main standard for bolts, nuts, and a wide variety of other threaded fasteners used in these countries.

The major minus pitch technique also works for inch-based threads, but you must first calculate the pitch by converting the fraction of threads-per-inch (TPI) into a decimal. For example, a screw with a pitch of 1/20 in (20 threads per inch) has a pitch of 0.050 in and a 1 ⁄ 13 in pitch (13 threads per inch) has a pitch of 0.077 in.

The coupling has a 5 ⁄ 8-24 UNEF thread. Amphenol suggests tightening to a torque of 15 inch-pounds (1.7 N⋅m), [2] while Andrew Corporation suggest 20 inch-pounds (2.3 N⋅m) for their hex nut variant. As torque limit depends only on thread quality and cleanliness, whereas the main operational requirement is good RF contact without ...

Machine quilting needles are very sharp in order to readily pierce layers of quilt and properly sew together the quilt top, batting and backing. Hand quilting needles are traditionally called betweens and are generally smaller and stronger than normal sewing needles. They have a very small eye which prevents any extra bump at the head of the ...
The F connector is not weatherproof. Neither the threads nor the joint between male connector body and captive nut provide a water-tight seal. However, male connectors are commonly enhanced with an o-ring (of about 7 mm) inside the captive nut. This seals between the mating faces of both connectors, providing some protection for the center ...
