The screw features a 3\/8-16 UNC thread with a 3\/4-inch length under the head and is fully threaded along its entire length. Drive engagement is through a 5\/16-inch internal hex socket, requiring an Allen or hex key for installation. Manufactured from alloy steel with a black oxide finish, this fastener delivers corrosion resistance and a clean, low-profile appearance suitable for machinery and structural connections where a recessed head is required.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for use in mechanical, electrical, HVAC, and plumbing equipment assemblies where a flush or countersunk fastener profile is needed. Fully threaded 3\/8-16 UNC screws are commonly used to secure brackets, panels, housings, and mounting hardware in both residential and light commercial equipment. The black oxide coating makes this fastener appropriate for indoor and semi-protected environments. Sold in multiples of 100 per order, this part is typically purchased by maintenance contractors, fabricators, and service technicians stocking fastener inventory.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC thread for compatibility with standard inch-series tapped holes\u003c\/li\u003e\n  \u003cli\u003eFully threaded construction maximizes thread engagement across the full 3\/4-inch body length\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch internal hex drive for precise torque application with an Allen key or hex bit\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASME B18.3 and ASTM A574 fastener standards\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces surface glare\u003c\/li\u003e\n  \u003cli\u003eLow-profile socket head sits flush or recessed in counterbored applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-stock hex socket cap screw for use in any application requiring a 3\/8-16 UNC fully threaded fastener conforming to ASME B18.3 and ASTM A574 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 5\/16-inch hex key or Allen bit driver.
