Types of Maxi Lock Thread

All-Purpose Thread:

Maxi-lock All Purpose Thread is manufactured to produce strong, consistent overlock stitches. This core spin polyester thread is mildew and UV resistant while boasting superior durability against breakage and resilience through hundreds of machine washes. You can use all-Purpose thread for decorative and construction seams, blind hems, quilting, and straight stitching. Each cone is 50wt and contains 3,000 yards.

Swirl Thread:

Maxi-Lock Swirl thread has the same high-quality construction as their all-purpose thread but in attractive variegated color options. Variegated threads have a multi-colored dye pattern that creates a gradient effect when stitched. Swirl Thread comes in a wide variety of color options, including contrasting tones that stand out and monochromatic ones that blend in seamlessly.


Maxi-Lock Stretch Thread is made of durable textured nylon that can withstand excessive heat, tension, and machine washing. Despite its strength, it retains a soft, supple, and yarn-like quality, which means you'll be able to create attractive seams with maximum comfort. Unlike bargain thread, Maxi-lock Stretch will not melt under the high heat of an iron or lose elasticity throughout the garment's life. Each cone contains 2,000 yards.
