It features a 3\/8-16 UNC thread size with 2 inches of length under the head and a 5\/16-inch hex drive socket. The fastener is partially threaded and manufactured from alloy steel with a black oxide finish coating that provides moderate corrosion resistance and reduces surface glare. It conforms to ASME\/ANSI B18.3 and ASTM A574 standards, making it a recognized choice where dimensional and tensile consistency are required. Licensed tradespeople and maintenance professionals install these in equipment assemblies, brackets, and structural connections across HVAC, mechanical, and general trade environments.\u003c\/p\u003e\u003cp\u003eThis screw is suited for use in light to medium-duty fastening scenarios where a recessed hex drive is required for clearance or torque reasons. The partial threading allows for clamping force between joined materials without thread engagement all the way to the head. Applications include equipment panels, mounting brackets, mechanical assemblies, and maintenance repairs in residential and commercial settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8-16 UNC thread size for standard inch-series fastening\u003c\/li\u003e\n\u003cli\u003e2-inch length under head with partial threading for strong clamping grip\u003c\/li\u003e\n\u003cli\u003e5\/16-inch hex socket drive for use with standard hex keys and Allen drivers\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction rated to ASTM A574 for reliable tensile strength\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish coating for mild corrosion resistance and low-glare appearance\u003c\/li\u003e\n\u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 and ASTM A574 compliant hex socket cap screw suitable for general mechanical and trade fastening applications requiring a 3\/8-16 UNC thread.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall and remove using a calibrated hex key or Allen driver sized to 5\/16 inch.
