The serrated flange distributes clamping load across a wider bearing surface while the serrations bite into the mating material to resist loosening under dynamic loads. The bolt is fully threaded at 1\/2-13 UNC with a length under head of 1-3\/4 inches, a flange diameter of 1.07 inches, and is manufactured from Grade 5 steel with a zinc-plated finish for corrosion resistance. It is installed using a standard hex drive and is suited for use by mechanics, millwrights, pipefitters, and general trade professionals working on equipment assemblies and structural connections.\u003c\/p\u003e\n\u003cp\u003eThis bolt is commonly used in residential and commercial mechanical installations where a built-in flange eliminates the need for a separate washer and where vibration resistance is a priority. Typical applications include equipment mounting, HVAC unit frame assembly, pump and motor bases, and general industrial or trade fastening tasks. The fully threaded shank allows engagement along the entire length of the bolt for short-grip applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSerrated flange eliminates the need for a separate lock washer and resists loosening under vibration\u003c\/li\u003e\n  \u003cli\u003eFully threaded 1\/2-13 UNC shank provides maximum thread engagement in short-grip applications\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction meets SAE J429 mechanical property requirements\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion resistance for indoor and moderate-exposure environments\u003c\/li\u003e\n  \u003cli\u003e1.07-inch flange diameter distributes clamping load to reduce surface stress on softer substrates\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.6.3 dimensional standards for consistent fit and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/2-13 UNC serrated flange bolt suitable for use in any application requiring a Grade 5 fully threaded hex flange fastener conforming to ASME B18.6.3 and SAE J429 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic, millwright, or trade professional using a standard hex wrench or socket driver sized for a 1\/2-13 UNC hex flange bolt.
