DaHo Hollow Spectra Mono Threading Needles
The DaHo Hollow Spectra Threading Needles are hollow inside, except for the point, so monofilament or fluorocarbon line can be inserted into the needle. Then, the needle with the internal mono/fluoro line, is inserted, or threaded, into the hollow center section of the spectra braid. The needle, and attached mono/fluoro line, is typically inserted inside of the spectra from 3 to 5 feet to provide the best strength of the join. Because of the slick surface of the mono/fluoro line, the end point of the spectra must be finished to secure it to the mono/fluoro line. This finishing is usually done by gluing, serving, crimping, or some combination of these attachments, to the spectra line end. This ensures the join will not slip before the compression pressure occurs in the braid of the hollow spectra line to hold the joined lines together.
The new DaHo Threading Needles 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 threading 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.
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. It is recommended that you select a needle that is at least .002" larger than your line for ease of use.
If your line is not on our charts, your line size can usually be found on the spool the line was purchased on, or by visiting the line manufacturer’s website. You will usually want to get a needle that will fit the line you are using, and provide and additional .002" of 'free' space to ease the insertion of your line.
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. 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.
In Threading needles, we typically use thinner walled tubing to manufacture the needle. This is so the overall size of the needle will remain as small as possible, while offering the largest interior size to hold the monofilament or fluorocarbon line you are using. Thinner is definitely better in this case, and our needles are the thinnest available.
