The new DaHo Threading Needles are shown above. As you can see, they have been sized by their length so if a customer has more than one of them, they can stand them on their open end and find the one they want by its length, compared to all the other threating needles. Our smallest threading needle, the 10 to 20# size, has a length of 5.3". Each larger threading needle is .1" longer than the last, with our largest 400 to 500# size being 6.5" in length. When we started, we spent a year gathering all of the requested features for our new needles. Having some way to identify the threading needle sizes was one that was requested many times. Due to their size and materials, the length was the only way to address this request.
The primary size of the threading needle is the ID, or Internal Diameter, indicating the approximate size of the mono/fluoro line that it will fit inside. The threading needle size you need is determined by the size of the mono/fluoro line you are using. The ID sizes of our threading needles can vary up to .002" due to the Stainless Steel Hypodermic tube manufacturing process. This is the standard acceptable size variance of the SS tubes we use to make our needles. As we receive new shipments of needles, the IDs may change up to this .002" size. It is recommended that you select a needle that is at least .002" larger than your line for ease of use. It can also be difficult to fit an exact size of line into a needle. If you have a problem with your line not fitting into one of our needles, please send us an email and we will analyze and resolve the problem.
If the mono/fluoro line is too large for the needle, you will have to cut it down, which is not much fun to do. The needles will hold smaller sizes of mono/fluoro line, up to a point, without issue. We offer most typically used sizes in our standard product offerings. We also offer 'special' sizes of needles for use with very small and large mono/fluoro lines, that are not commonly used. All are named for the typical size range of mono/fluoro that they will hold, but you really need to select your needles by the actual size of your mono/fluoro line, as the line size can vary a lot.
