Needle Types
Ultrafeed Sewing Machines require 135x17 or 135x16 needles sizes #10 to
#22, all available at Sailrite®.
Round/Sharp Point needles are used for all general
sewing. Serv7 needles are modified Round Point
needles that have an extended shoulder to prevent
skipped stitches and reduce needle breakage.
SAN 5.2 needles can sew the same materials as Round/
Sharp Point needles but with fewer issues such as
deflection, needle breakage and material damage. They are
ideal for sewing slippery threads like PTFE or lifetime thread
and are more resistant to needle gumming from basting tape.
SD1 needles are optimized for fine leather; they also work
well for sewing heavy sailcloth assemblies. The needle
partially cuts, then pushes material fibers out of the way.
Ball Point needles are specifically designed for use with knit
or stretchy materials. The blunt tip on this needle passes
thread between material fibers instead of through them.
