WebApr 10, 2024 · British Standard Fine (BSF) is a screw thread form that was developed by R. E. B. Crompton, and his assistant George Field and was introduced by the British … WebPresented by the British Engineering Standards Association, BSF was identical to the original Whitworth form except that the pitch was finer—meaning more threads per inch. Now a bolt with a diameter of 1/4 inch could have either 20 threads per inch (BSW) or 26 (BSF). The advantage of the finer thread pitch is two fold.

WebZinc-plated steel fittings have mild corrosion resistance. Fittings with a check valve prevent grease from leaking when pressure causes backward flow. The valve stays closed when not in use to keep out dirt and other contaminants. For technical drawings and 3-D models, click on a part number. WebThe Thread Profiles were kept, but some of the less popular sizes were dropped. Angle of thread = 60°. Cycle Engineers' Institute (CEI) or British Standard Cycle (BSC) These are different names commonly used for the same threads. 60 degree thread angle, rather than the 55 degree of BSW and BSF. WebThe British Standard Fine (BSF) thread has the same profile as the BSW thread form but was used when a finer pitch was required for a given diameter. If p = pitch of the thread d = depth of the thread r = radius at the top and bottom of the threads then: d = 0.640327 p r = 0.137329 p British Standard Brass (BSB) Threads medication temazepam substitutes
