There are two types of BSP threads; - BSPP - male thread are both (also known as G) - BSPT - thread is parallel and the male thread is tapered (also know as R/Rp) (the thread can also be tapered it is then Rc, these are fairly rare to find).

This refers to a British Standard Pipe thread tapered (EN 10226) with an internal parallel form (Rp) and a nominal size of 2 ½. The actual sizes of the most commonly used BSP threads are

There are two unsanctioned screw thread plug gage options for testing the Rp screw thread: 1. Specially made Rp-series GO/NOGO parallel screw thread plug gages. These gages are not defined in any specification. 2. The same size designated G-series GO/NOGO screw thread plug gage.

Note) · Set the finishing allowance on a diameter at approx. .004 inch when using a full form insert. · Please note the cutting depth and the number of passes when a nose radius of a partial or semi-full form insert or of an internal threading insert is

There are two types of BSP Thread available. One is Parallel threads or we can say Straight threads. The second one is the Taper Thread. BSP is BRITISH STANDARD PIPE THREAD- Also known as Whitworth 55° Thread Form. BSPT is BRITISH STANDARD PIPE TAPER THREAD - Thread form per AS 1722.1, BS 21, ISO 7.

Use a caliper to measure the nominal male or thread crest-to-crest diameter on the first, fourth, and last full threads (Fig . 1) . T. If the diameters 

BSPT = British Standard Pipe Taper is an obsolete designation still in common usage which has been replaced with the R-Series. R = External tapered screw pipe thread for fits made on the thread per ISO-7 & BS-21. Per the standard the R mates with the Rc and Rp, but will also mate with the G. Rc = internal tapered threads for fits made on the

These metric pipe thread sizes have been adopted by the ISO (International Internal parallel threads: “Pipe thread ISO 7/1-Rp 1½˝ (for example).

For metric threads, this tool measures the distance between the threads. If you're looking to buy a thread pitch gauge, Grainger has a pretty good selection. How to Identify Different Types of Threads Step 1 - Male Threads v. Threads First, you'll need to identify whether the thread type is male or female.

Explanation: Pitch: Designated by "X P". For example, M8 X 0.75 means an 8 mm (0.315″) thread with a pitch of 0.75 mm (0.03″ or 34 TPI).If the "X P" is omitted, the pitch is defined by the Coase Pitch Series according to ISO-261. Number of starts: Designated by "Ph".For example, M8 X Ph2.25P0.75.In this case, 2.25 mm is the lead, and 0.75 mm is the pitch.
