Zinc alloy is selected for this specific size because it offers excellent casting detail, beautiful plating finish, and high structural toughness under indoor vertical hanging loads at a highly cost-effective value.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Will the set screw scratch the surface of my metal pipes during installation?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Yes. The set screw is designed to apply direct mechanical pressure onto the pipe surface to lock it into position. This leaves a small dimple or scratch mark on the pipe surface where the screw contacts it. This mechanical bite is necessary to prevent the joint from slipping under load, which is why brittle materials like glass cannot be used.\u003c\/p\u003e\n\n\u003c!-- Recommended System Bundles \u0026
