Featuring a 3\/8-16 UNC thread size and a 5\/16-inch hex drive, this screw is partially threaded with a 2.5-inch length under head. The alloy steel construction provides excellent tensile strength, while the black oxide finish offers mild corrosion resistance and a clean appearance. Sold in a pack of 10, this fastener meets ASME B18.3 and ASTM A574 standards. It is well suited for maintenance, repair, and fabrication work across trade and industrial settings.\u003c\/p\u003e\u003cp\u003eThis screw is used in applications requiring a recessed hex drive for flush or countersunk installations where a standard hex head is not practical. The partial threading engages clamping force across the grip length, making it appropriate for bolted joints in metal-to-metal assemblies. Typical users include mechanical contractors, millwrights, HVAC fabricators, and general tradespeople working on equipment mounting, panel fastening, and structural connections. The 10-piece pack quantity suits service calls and small-batch repair jobs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8-16 UNC thread for broad tool and hardware compatibility\u003c\/li\u003e\n\u003cli\u003e5\/16-inch hex socket drive for Allen wrench or hex bit installation\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank for improved clamping and grip strength\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 high-strength fastener standard\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating provides mild corrosion resistance and reduced glare\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B18.3 socket cap screw dimensional standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 3\/8-16 UNC hex socket cap screw suitable for use in any threaded hole or nut conforming to the 3\/8-16 UNC thread standard in mechanical and structural assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall using a 5\/16-inch hex key or hex bit driver.
