LWX3T Needle Size 1 1/2| Blind Hemmer 5 PK
The LWx3T (also known as the 251, 29-C-300, or SY3690) is a specialized industrial needle system designed for blindstitch (blind hem) machines. It is uniquely curved to allow the needle to catch only a few fibers of the fabric's surface, creating a hem that is nearly invisible from the outside.
Key Technical Specifications
The "T" in LWx3T often indicates a specific needle geometry or finish (such as titanium or a specific taper) depending on the manufacturer.
