Description

British Standard Fine (BSF) Hex Nyloc Nuts is a screw thread form, as a fine-pitch alternative to British Standard Whitworth (BSW) thread. It was used between the 30's to even the 70's on British and Australian machinery, motor vehicles and farming equipment prior to adoption of Unified, and later Metric standards. It is now being discontinued by many of the the major UK manufacturers and sizes making it harder to source, especially in any volume so pricing reflects that
Also known as: Nylon Insert Nut, Nylon Lock Nut
Material / Coating: Zinc Plated is the most common fastener of plating due to its the low cost and shinny bright silver finish. A thin layer of zinc is applied by either electroplating or mechanically
What does TPI stand for?: TPI stands for “threads per inch” which literally means the number of threads within each inch on a nut, a bolt, or a fastener. To determine the TPI of a nut, either count the number of threads contained within an inch of length on the male fastener or use a thread checker. If the male fastener is less than an inch, measure 1/2", count how many there are then multiply the number by 2
