It features a partially threaded shank, a coarse UNC thread form, and measures 1-1\/2 inches under the head. Manufactured from Grade 5 steel with a zinc-plated finish for basic corrosion resistance, this fastener conforms to ASME B18.2.1 dimensional standards. It is suitable for use in light to medium-duty assemblies where a standardized hex drive fastener is required. Electricians, HVAC technicians, plumbers, and general maintenance trades routinely use this screw size in equipment mounting, panel work, and bracket installations.\u003c\/p\u003e\n\u003cp\u003eThis fastener is well suited for residential and light commercial mechanical applications. The 5\/16-18 coarse thread makes it compatible with standard tapped holes and hex nuts of the same designation. The partial threading allows the unthreaded shank to act as a shoulder or grip section in through-bolt installations. Sold in a pack of 50 units, this screw is practical for stocking in service vehicles or shop inventory where this common size is frequently needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC coarse thread for broad compatibility with standard tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003e1-1\/2 inches length under head for versatile fastening depth\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction meets medium-strength fastener requirements\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides basic corrosion protection in dry or mildly humid environments\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank allows use as a shoulder bolt in through-bolt applications\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standards for consistent fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 5\/16-18 UNC tapped holes, hex nuts, and washers in inch-measurement mechanical assemblies conforming to ASME B18.2.1 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation typically requires a standard hex wrench or socket set sized for a 5\/16-18 fastener. Verify that the mating thread is clean, undamaged, and of the same UNC thread form before driving. Do not overtighten, as Grade 5 steel has defined proof load limits that should not be exceeded.
