DaHo Hollow Spectra Threading Needles

The new DaHo Threading Needles are shown above. Each needle is uniquely sized by length, allowing users to easily identify the correct tool when multiple needles are in use. By standing the needles on their open end, the correct size can be quickly selected by comparing lengths.

Our smallest threading needle (10–20 lb range) measures 5.3 inches, and each successive size increases by 0.1 inches, with the largest (400–500 lb range) measuring 6.5 inches. This length-based identification system was developed after extensive customer feedback and provides a simple, reliable way to distinguish between sizes.

How They Work

DaHo Hollow Spectra Threading Needles are designed with a hollow shaft (except at the point), allowing monofilament or fluorocarbon line to be inserted directly into the needle.

Once inserted, the needle—along with the internal line—is threaded into the hollow core of the Spectra braid. For optimal strength, the needle and line are typically inserted 3 to 5 feet inside the braid.

Due to the smooth surface of mono and fluorocarbon lines, the exposed end of the Spectra must be secured using one or more of the following methods:

• Gluing

• Serving

• Crimping

• Combination of methods

This finishing step ensures the connection remains secure until the braid compresses and locks the lines together under tension.

Selecting the Correct Needle Size

The primary sizing factor for threading needles is the Internal Diameter (ID), which determines the size of mono or fluorocarbon line that can be inserted.

• Select a needle based on the actual diameter of your line, not just the labeled strength

• Due to manufacturing tolerances, needle IDs may vary by up to ±0.002 inches

• For best performance, choose a needle that is at least 0.002 inches larger than your line diameter

This slight clearance allows for easier insertion and smoother operation.

If your line does not fit properly, please contact us—we are happy to assist in selecting the correct size or resolving fit issues.

Line Compatibility

If your line is not listed in our charts:

• Check the spool packaging

• Visit the manufacturer’s website for diameter specifications

Line diameters can vary significantly between brands, even at the same pound rating, so sizing by diameter is always recommended.

Standard and Custom Sizes

We offer a full range of commonly used sizes, along with specialized sizes for:

• Very small diameter lines

• Extra-large diameter lines

All needles are labeled based on typical line ranges, but final selection should always be based on actual line diameter.

Design Advantage

DaHo threading needles are manufactured using thin-walled stainless steel tubing, allowing for:

• Smaller overall needle diameter

• Larger internal capacity

• Easier insertion into tight braid structures

Thinner wall construction improves performance while maintaining strength—making these needles among the finest and most precise available.

Notes

• Internal Diameter (ID) may vary by up to ±0.002″ due to stainless steel tube manufacturing tolerances.

• For best performance, select a needle with an ID at least 0.002″ larger than your line diameter.

• If your line does not fit properly, please contact us—we will assist in selecting the correct size.
