These common problems often stem from a worn or damaged shuttle hook tension spring and screw. Without proper tension, your machine cannot form balanced stitches, leading to costly reworks and lost production time. This 2-set Evernice Shuttle Hook Tension Spring and Screw (#8611 and #662) is the precise replacement you need to restore your machine&#8217;s ability to create perfect, consistent embroidery.<\/p>\n<h3>Restore Precision Thread Tension<\/h3>\n<p>The shuttle hook tension spring and screw are critical components that regulate the lower thread tension, working in harmony with your bobbin case. A correctly functioning spring provides the necessary resistance, allowing the bobbin thread to feed smoothly and consistently, while the screw allows for fine-tuning this tension. When these parts are worn, bent, or missing, the delicate balance of thread tension is compromised, resulting in uneven stitches, looping, or puckering. Replacing them with this high-quality set ensures your Singer 29K machine can once again produce the clean, professional embroidery your business demands.<\/p>\n<h3>Designed for Consistent Performance<\/h3>\n<p>This essential set is designed for Singer 29K sewing machines using small bobbins (#8604) and is compatible with a range of models, ensuring broad utility for many embroidery professionals:<\/p>\n<ul>\n<li>Singer 29-1<\/li>\n<li>Singer 29K71<\/li>\n<li>Singer 29K73<\/li>\n<li>Singer 29K171<\/li>\n<li>Singer 29U171A<\/li>\n<li>Singer 29U173A<\/li>\n<\/ul>\n<h3>Product Specifications<\/h3>\n<ul>\n<li><strong>Brand:<\/strong> Evernice<\/li>\n<li><strong>Part Numbers:<\/strong> #8611, #662<\/li>\n<li><strong>Set Type:<\/strong> Yes (2 sets included)<\/li>\n<li><strong>Use:<\/strong> Embroidery, Sewing Machine Parts<\/li>\n<li><strong>Material:<\/strong> Other (standard durable component material)<\/li>\n<\/ul>\n<h3>Confidence in Every Purchase<\/h3>\n<p>At 360 Digitizing Shop, we understand that reliability is paramount.
