1 Seldén rigging screws are made from high-grade, marine stainless steel. The rigging screws have cold rolled threads and are polished for higher corrosion resistance. The threads are lubricated with Seldén rigging screw oil prior to delivery.
To keep your rigging screws in good condition, please clean and lubricate them
regularly with our special rigging screw oil. Stainless steel rigging screws

Back in 1998 we changed the clevis pin diameter from Ø 13 mm to Ø 15.8 mm. When upgrading to new rigging
screws on a boat built prior to this change, the clevis
pin will most likely be bigger than the chain plate hole.
The Ø 15.8 mm clevis pin has to be replaced by one
Ø 13 pin and two bushings.
