Is BSF the same as Whitworth?
Whitworth thread is coarser than a BSF of the same diameter,but the same spanners are used on both ranges,and are often marked with both Whitworth and BSF sizes . A whitworth spanner or socket is larger than one marked with the same size in BSF for example a 1/4 inch whit is the same physical size as a 5/16inch BSF.
What does BSF thread mean?
British Standard Fine
British Standard Fine (BSF) is a screw thread form, as a fine-pitch alternative to British Standard Whitworth (BSW) thread. BSF threads use the 55 degree Whitworth thread form. It was introduced by the British Engineering Standards Association in 1908.
What size is 3/8 BSF?

How are BSF bolts measured?
The length of a Hexagon bolt is determined by measuring from underneath the head to the end of the bolt. If the bolt has a countersunk head, the full length of the bolt including head is measured.
What is the pitch of 6/32 thread?

|---|---|---|
| #6 – 32 | 32 | 0.794 |
| #8 – 32 | 32 | 0.794 |
| #10 – 24 | 24 | 1.058 |
Is BSF the same as BSW?
Both of these thread types are use for imperial thread. BSF and BSW are Britisch measurement systems, while UNF and UNC are American measurement systems. BSF and UNF are the fine thread systems, while BSW and UNC are the coarse thread systems. The BSF/BSW have a wave like thread profile.
Is UNF and NF thread the same?
NC and UNC mean coarse thread. NF and UNF mean fine thread. Pitch Diameter is the basic dimension of a screw, threaded hole, or a tap the diameter of an imaginary cylinder, the surface of which passes through the thread where width of thread and space between threads are identical.
How is BSF bolt measured?
Is BSF same as BSP?
British Standard Pipe (BSP) technical standards for screw threads that has been adopted internationally for interconnecting and sealing pipes and fittings by mating an external (male) thread with an internal (female) thread. British Standard Fine (BSF) has a finer thread pitch and smaller thread depth.
What does 8 UNC mean?
UNC: Is the symbol for Unified coarse pitch threads. UNF: Is the symbol for Unified fine pitch threads. UNEF: Is the symbol for United extra fine pitch threads. UNS: Is the symbol for Unified special threads.

What is BSF thread used for?
British Standard Fine (BSF) is a screw thread form, as a fine-pitch alternative to British Standard Whitworth (BSW) thread. It was used for steel bolts and nuts on much British machinery, including cars. Before the adoption of Unified, and later Metric, standards.
What is the difference between BSF thread and tpi thread?
BSF threads use the 55 degrees Whitworth thread form. It was introduced by the British Engineering Standards Association in 1908. The table shows suitable for tapping drill sizes. 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.
What is BSc thread used for on a car?
It was used for steel bolts and nuts on much British machinery, including cars. Before the adoption of Unified, and later Metric, standards. For highly stressed conditions, especially in motorcycles, a finer thread, British Standard Cycle (BSC), was used as well.
