Stainless steel and Xylan Coated eyelet screws
Normally used for sewing, jewellery making, art and craft
These eyelets are either A2 (T304) stainless steel or xylan coated. Xylan is a PTFE / Teflon coating which reduced friction. This allows the cord to slip while reducing the tendancy for chaffing the cord.
