{"title":"Coupling Nuts","description":"\u003cp\u003eCoupling nuts are long hex nuts used to join two pieces of threaded rod or extend the reach of a bolt or stud. Their extended length engages more threads for a strong, in-line connection. They're essential for building up threaded rod runs in hangers, anchors, and tie rods. We stock coupling nuts across grades and materials in coarse and fine thread.\u003c\/p\u003e\n\u003ch2\u003eHow Coupling Nuts Work\u003c\/h2\u003e\u003cp\u003eA coupling nut threads onto two rods from opposite ends, joining them into a longer continuous threaded length. The long body ensures ample thread engagement on each rod for full strength. Some have a sight hole or witness mark at the center so you can confirm each rod is threaded in to the proper depth.\u003c\/p\u003e\n\u003ch2\u003eThread Engagement Matters\u003c\/h2\u003e\u003cp\u003eFor full strength, each rod should engage at least the rod's diameter in thread length inside the coupling — ideally to the center. Under-engaging one side creates a weak joint. The center sight hole, where present, helps verify both rods meet properly.\u003c\/p\u003e\n\u003ch2\u003eMaterials and Finishes\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eSteel\u003c\/strong\u003e with zinc plating: the economical standard. \u003cstrong\u003e18-8 and 316 stainless\u003c\/strong\u003e for corrosion resistance.

Thread each rod in to at least the center for full strength. Choose stainless for corrosion resistance. Verify the coupling length suits your engagement needs — left-right (turnbuckle-style) couplings exist for adjustable assemblies.\u003c\/p\u003e\n\u003cp\u003eUse the filters to narrow by size, material, and thread pitch.\u003c\/p\u003e","products":[{"product_id":"10-24-x-3-4-5-16-af-hex-coupling-nuts-steel-zinc","title":"#10-24 X 3\/4\" (5\/16\" AF) Hex Coupling Nuts \/ Low Carbon Steel \/ Zinc","description":"\u003cdiv style=\"font:400 15px\/1.65 -apple-system,BlinkMacSystemFont,'Segoe UI',Roboto,Helvetica,Arial,sans-serif;color:#111827;max-width:52em;\"\u003e\n\u003cp style=\"margin:0 0 18px;font-size:16px;\"\u003e#10-24 x 3\/4\" coupling nut in Low Carbon Steel, zinc finish.\u003c\/p\u003e\n\u003cul style=\"margin:0 0 4px;padding-left:1.1em;\"\u003e\n\u003cli style=\"margin:0 0 11px;\"\u003e\n\u003cspan style=\"font-weight:700;color:#0f4c5c;letter-spacing:.03em;font-size:13px;\"\u003eCARBON STEEL\u003c\/span\u003e\u003cspan style=\"color:#6b7280;\"\u003e — \u003c\/span\u003estrong and inexpensive, but it depends entirely on its plating for corrosion protection\u003c\/li\u003e\n\u003cli style=\"margin:0 0 11px;\"\u003e\n\u003cspan style=\"font-weight:700;color:#0f4c5c;letter-spacing:.03em;font-size:13px;\"\u003eZINC PLATED\u003c\/span\u003e\u003cspan style=\"color:#6b7280;\"\u003e — \u003c\/span\u003ean electroplated barrier for interior and sheltered work;
