{"title":"Pop Rivets for Seldén Spars","description":"\u003cp\u003eSeldén pop rivets in Monel, stainless steel and aluminium for dinghy mast and boom fittings, covering ø3.2 mm, ø4.8 mm and ø6.4 mm diameters in dome head and countersunk versions.\u003c\/p\u003e\n\u003ch2\u003eHow to choose\u003c\/h2\u003e\n\u003cp\u003eThe most important decision is matching rivet material to your spar. \u003cstrong\u003eStainless steel rivets are specifically designed for carbon spars.\u003c\/strong\u003e When a conventional rivet is pulled up on carbon, the bulbous collapse of the mandrel can crack the surface. Stainless steel rivets collapse flat instead, spreading the load like a washer. If you are riveting onto a carbon mast, boom or fitting, you need the stainless steel variants — not Monel, not aluminium.\u003c\/p\u003e\n\u003cp\u003eFor aluminium spars, Monel is the correct choice. Monel is a nickel-copper alloy that resists saltwater corrosion more effectively than stainless steel in prolonged marine exposure. It is the standard rivet material for Seldén aluminium dinghy spars and fittings. Aluminium rivets are available where weight is a priority and the corrosion environment is less demanding.\u003c\/p\u003e\n\u003cp\u003eOnce you have the right material, match diameter and length to the fitting being installed. Diameter must correspond to the hole in the fitting. Length must be sufficient to grip the combined thickness of the materials being joined. When in doubt, consult the fitting's installation instructions or contact Seldén.\u003c\/p\u003e\n\u003cp\u003eHead type is the final choice. Dome head is standard for most mast fitting applications. Countersunk is used where the rivet head must sit flush with the surface — typically where a fitting slides over the rivet or where a clean profile is required.\u003c\/p\u003e\n\n\u003ch2\u003eWhat's in this collection\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eStainless steel rivets\u003c\/strong\u003e for carbon spars are available in ø4.8 mm and ø6.4 mm diameters. The ø4.8 mm range covers lengths of 6 mm (167-032), 8.5 mm (167-033) and 11 mm (167-053). The ø6.4 mm option is 12.7 mm long (167-031).
