It carries a 1\/2-20 UNF thread size and measures 1 inch in length under the head. Drive engagement is through a 3\/8 inch hex socket. The black oxide coating provides mild corrosion resistance and reduces light reflection on the fastener surface. This screw meets ASME B18.3 and ASTM A574 standards, making it suitable for high-strength bolted joint applications in mechanical, HVAC equipment, and general industrial assemblies. Installation requires a 3\/8 inch hex key or socket driver.\u003c\/p\u003e\n\u003cp\u003eThis fastener is used in a wide range of trade and industrial applications where a high-strength, flush or low-profile cap screw is required. Common uses include securing mechanical components in HVAC equipment, pump housings, electrical enclosures, and structural assemblies. The fine 1\/2-20 UNF thread pitch provides stronger thread engagement and improved resistance to vibration loosening compared to coarse thread equivalents, making it a preferred choice in precision or vibration-prone assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-20 UNF fully threaded for maximum thread engagement along the full shank length\u003c\/li\u003e\n  \u003cli\u003e1 inch length under head suits medium-depth fastening applications\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch hex socket drive for standard hex key or socket wrench installation\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 high-strength fastener requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and a low-reflectance surface\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.3 dimensional standard for hex socket cap screws\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard hex socket cap screw for applications requiring a 1\/2-20 UNF, 1 inch length under head, alloy steel fastener per ASME B18.3 and ASTM A574.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or technician using a 3\/8 inch hex key or socket drive tool.
