For industrial sewing threads it is important to understand the following terms: Tex - Weight in grams of 1,000 m of thread.Denier - Weight in grams of 9,000 m of thread.Cotton Count (NeC) - Weight in pounds of 840 yards. Industrial thread sizes are usually expressed by Tex size or Ticket number. When only the total Denier is known, to.

UNC - 60 Degree Unified Coarse Threads. UNC Thread Series / UNRC are the one most commonly used in the bulk production of bolts, screws, nuts and other general engineering applications. It is also used for threading into lower tensile strength materials such as cast iron, mild steel and softer materials (bronze, brass, aluminum, magnesium and

International standards require all thread is parallel and male thread is tapered. The thread can also be tapered but this is not common. Thread Count (TPI) TPI stands for Threads Per Inch, which means the total number of threads per inch measured along the length of a fastener. TPI is used only with American fasteners.

For example, 8/16" or 1/2" equates to size -8 . Note: dash numbers are nominal. Since metric measurements give the true sizes of a tube or a fluid pipe, dash numbers do not apply for them. For example, for M12x1.0, the outer diameter of the threads is 12 mm with a 1.0 mm spacing between threads, Hydraulics Direct Reviews

When the diameter smaller than 1/4", the value is indicated by a number, like #1 or No.1. 2.Thread sizes in metric are specified by diameter and pitch. The metric thread sizes are generally expressed as M2 × 0.25, the thread diameter is 2mm and pitch is 0.25mm. Thread Dimensions - Imperial Thread Sizes Chart

As with NPT threads, the nominal size does not represent true outside pipe diameter but in the larger sizes it comes very close. Sizes start at 1/16˝ and go up through 6 inches. Note: there is no ISO thread modification such as the NPTF (National Pipe Thread Fuel) for improved sealing between threads. Usually a thread sealant is required.

NPT/NPS threads have a 60° angle and have flattened peaks and valleys (Sellers thread form) where as BSP threads have a 55° angle and have rounded peaks and valleys (Whitworth thread form). NPT and BSP thread pitches (threads per inch) are listed below. To determine pitch, use a thread gauge or count the number of threads that fall into a 1

Each thread in the series is characterized by its major diameter D maj and its pitch, P.UTS threads consist of a symmetric V-shaped thread. In the plane of the thread axis, the flanks of the V have an angle of 60° to each other. The outermost 1 ⁄ 8 and the innermost 1 ⁄ 4 of the height H of the V-shape are cut off from the profile.. The pitch P is the distance between thread peaks.

Minimum = 0.033P for all pitches. See table for maximum. When using L1 gauges to check threads, the thread is within permissible tolerance if the ring gauge face, or plug gauge notch, is +/- 1 turn from being flush with the end of the thread. Example designation: 3/8 - 18 NPT. where: 3/8 = nominal pipe size. 18 = number of threads per inch.

Sealing is provided by a pre-coating on the thread. Thread designation • BSP Parallel (BSPP): G followed by the denomination, according to standard ISO 228-1. Example: 1/8 BSP parallel thread = G1/8 • BSP Taper (BSPT): R followed by the denomination, according to standard ISO 7-1. Example: 1/8 BSP taper (BSPP) thread = R1/8 • threads:

An M6 thread has a basic major diameter of 6 mm.Typically, metric thread callouts also come with the thread pitch, such that an M6 × 0.1 threaded bolt has a basic major diameter of 6 mm and a thread pitch of 0.1 mm.When purchasing a threaded fastener, make sure you have both the diameter and the thread pitch.
