The fastener uses a 5\/16 inch hex drive and features a 3\/8-16 UNC thread with 3 inches of length under the head. Constructed from alloy steel with a black oxide coating, it delivers solid mechanical strength and moderate corrosion resistance in controlled environments. Partial threading allows the shank to bear shear loads while the threaded portion grips the mating material. This type of fastener is installed by HVAC technicians, millwrights, pipefitters, and general maintenance professionals across a range of equipment types.\u003c\/p\u003e\u003cp\u003eThis screw is suited for use in light industrial and mechanical service applications where a recessed drive is required for flush or countersunk installation. The 3\/8-16 UNC coarse thread pattern threads quickly into tapped steel, aluminum, or cast iron bores and provides reliable clamping force in both residential and commercial service environments. The black oxide finish blends with dark mechanical surfaces and reduces light reflection in service panels and enclosures.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8-16 UNC coarse thread for fast engagement in standard tapped holes\u003c\/li\u003e\n\u003cli\u003e3 inches length under head with partial threading for shear load capacity\u003c\/li\u003e\n\u003cli\u003e5\/16 inch hex socket drive for use with standard hex keys and socket drivers\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASME\/ANSI B18.3 and ASTM A574 fastener standards\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating provides surface protection and low-reflectance finish\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service fastener for mechanical assemblies requiring a 3\/8-16 UNC partially threaded hex socket cap screw conforming to ASME\/ANSI B18.3 and ASTM A574 standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall using a calibrated hex key or socket driver sized to 5\/16 inch.
