Each tab measures 2-1\/2\" tall, 1-3\/4\" wide and 1\/4\" thick, and comes pre-treated to reduce warpage, hydrogen content, and surface contamination so you get reliable joints with common MIG\/TIG filler wires.\u003c\/p\u003e\n\n\u003ch3\u003eHow are these tabs built to resist tear-out and vibration?\u003c\/h3\u003e\n\u003cp\u003eThe Alvktora tabs use a thicker edge profile and anti-sway center-hole control to stop fasteners from canting under load.

The plates receive pickling treatment to significantly delay surface rust, and they perform even better when coated or primed after welding.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eIdeal for suspension brackets, trailer hitches, rock-crawler mounts and hydraulic frames.\u003c\/li\u003e\n  \u003cli\u003ePickling treatment extends rust delay up to three times longer than untreated steel.\u003c\/li\u003e\n  \u003cli\u003eCombine with primer\/paint for multi-year outdoor protection (provisioning dependent).\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for? These weld-on tabs suit fabricators, off-road builders, trailer and hitch manufacturers, and serious DIYers who need compact, repeatable mounting points that resist vibration and tearing. If you require consistent weld performance under heavy loads and want prefabricated tabs that minimize prep and post-weld rework, this 8-piece Alvktora pack is designed to save time and improve joint reliability.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Are these tabs ready to weld out of the box?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
