Gutermann Bulky Lock 160 Overlocker Thread - 2000 Metres

It is ideal for medium-weight and lightweight fabrics, including cottons, linens, knits, and blends. It provides a soft finish on fabrics like jersey, chiffon, and silk.

This thread is optimized for overlockers and coverstitch machines. While it might function in some conventional sewing machines for specific decorative stitches, it is not recommended for standard straight stitching as its thickness and construction are designed for different machine types.

Bulky Lock 160 is a thicker, elastic thread designed to create a softer, more voluminous seam finish on cut edges. Regular overlocker threads are often thinner and designed for durability and seam construction rather than a soft aesthetic.

'No 160' refers to the thread's thickness or system count. A lower number generally indicates a thicker thread, so No 160 is a finer, bulkier thread suitable for specific applications.

The Gutermann Bulky Lock 160 is available in 12 different shades.

No, this thread is designed for lighter fabrics and decorative finishes. For heavy-duty seams like on jeans, a thicker, stronger thread such as Gutermann HT2 or similar would be more appropriate.

Ensure the needle is new and correctly inserted, and check that the machine is threaded with Bulky Lock 160 in all guides. Adjust tensions if necessary.

Check for burrs on the machine's needle plate or tension discs. Lower machine speed and ensure correct threading. Verify tension settings are not too high.

Adjust the differential feed on your overlocker. Increase differential feed for stretchier fabrics to prevent wavy seams. Check looper tension.

Verify the looper threading sequence is correct. Ensure the Bulky Lock 160 is seated properly in the looper tension discs.
