Package includes 20 Singer Genuine Machine Needles ( 10 x Universal 2020, size 90/14 and 10 x model 2045, size 90/14 needles) that can be used on many other machines such as Brother and other high quality sewing machines. SINGER 2020 UNIVERSAL Size 90/14 Sewing Machine Needles are designed for sewing medium weight woven fabrics. SINGER 2045 Size 90/14 Ball Point Needles make sewing knits and synthetic fabrics easy and simple. No more skipping stitches, loose or inconsistent stitch quality. This needle has a medium tip that is slightly more rounded than a universal needle and passes between the fabric threads instead of piercing them. Ball-point needles ensure more even stitches on coarse and medium knits and wont damage spandex, interlocks and other knits that stretch and give. The shank of the needle secured by the needle clamp screw is slightly smaller than universal needles. This brings the scarf in the needle, just above the eye, slightly closer to the sewing machine hook point, thus, helping to eliminate skipped stitches. Singer recommends that you use only genuine Singer sewing machine needles in your Singer sewing machine. By using genuine singer needles, your machine will perform to its fullest potential.
