UTC Ultra Thread

Ultra Thread is a premium, non-waxed fly tying thread prized for its incredible strength-to-diameter ratio and its unique ability to lay perfectly flat. It is the go-to choice for fly tyers who need a thread that can resist snapping and create perfectly neat, low-bulk flies.

Ultra Thread, a product from the USA-based Ultra Thread Company (UTC), quickly established itself as a major player in the fly tying industry. They carved out a reputation for producing innovative, high-quality synthetic threads and materials that quickly became favorites among both professional and hobbyist tiers. The brand is synonymous with quality and reliability in the fly tying community.

The thread is made from a continuous filament of spun polyester, a material chosen for its durability and impressive tensile strength. Unlike other threads, it is purposely left unwaxed, which allows the filaments to be spun into a perfectly flat profile. This flat-laying property is a key benefit, as it minimizes bulk on the hook shank and allows for a smooth, professional finish. The thread is then carefully spooled to maintain its quality and consistency.
This thread comes in both 70D and 140D, (Denier) making it a versatile workhorse for tying a huge range of patterns, from small and medium dry flies to nymphs and streamers. Its flat profile is a major advantage, as it creates smooth, uniform bodies and helps to avoid a bulky look, which is essential for realistic flies.

Despite its fine diameter, it is surprisingly strong and can be pulled tight to secure materials without the fear of snapping. The lack of wax makes it ideal for tiers who prefer to add their own wax or for patterns where a non-tacky finish is desired.

UTC Ultra Thread is available in a vast selection of popular and vibrant colors to match any fly pattern you can imagine. It comes sold in 100 yard spools, allowing you to tie dozens of flies.
