Seldén Rigging Screws: Types and Features

Seldén Rigging Screws for Yacht Standing Rigging

Seldén rigging screws provide the adjustment used to tension yacht shrouds and stays. Selecting the correct rigging screw means matching more than the overall size: the thread, wire diameter, clevis-pin diameter, fork width, terminal arrangement and required articulation all need to suit the standing rigging and the yacht's attachment fittings.

Seldén's traditional bronze rigging screws use a chrome-plated aluminium-bronze body with high-grade marine stainless-steel terminals. This combination provides high corrosion resistance while reducing the risk of stainless threads seizing under heavy load.

How to Choose the Correct Rigging Screw

Measuring Rigging Screws for Replacement Standing Rigging

If the rigging screw forms part of a stay or shroud being copied, return it to the marked or recorded working position before measuring the finished assembly. Measure between the correct bearing points and record the adjustment position so the new rigging can retain an appropriate range for tensioning.

See our standing rigging measurement guide for illustrated measurement advice.

Rigging Screw Maintenance

Rigging screws should be inspected for corrosion, damaged or distorted threads, worn pins, damaged forks and signs of cracking or deformation. Threads should remain clean and move correctly; use maintenance products and lubrication appropriate to the specific manufacturer's instructions.

If a rigging screw is seized, damaged or badly worn, do not force it back into service simply because the standing-rigging wire itself appears satisfactory.
