Manufactured from alloy steel with a black oxide finish, it meets ASME\/ANSI B18.3 and ASTM A574 standards for dimensional and mechanical compliance. The 1\/4-28 UNF thread size provides a fine-pitch engagement suitable for applications where vibration resistance or precise load control is important. Drive size is 3\/16 inches hex. This screw is installed by maintenance technicians, pipefitters, millwrights, and general mechanical tradespeople across industrial, HVAC, and equipment assembly settings.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for use in light to medium mechanical assemblies, equipment enclosures, machine components, and structural hardware applications. The fine-thread 1\/4-28 UNF specification is common in precision assemblies and situations where tensile load and controlled torque are prioritized. The partial threading and 1-3\/4 inch length under head allow for secure clamping across a range of material stack thicknesses. The black oxide coating offers mild corrosion resistance and a low-reflectance finish for indoor and sheltered environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-28 UNF fine-thread specification for vibration-resistant fastening\u003c\/li\u003e\n  \u003cli\u003e1-3\/4 inches length under head with partial threading for reliable clamp load\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch hex drive for standard hex key or Allen wrench installation\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and matte appearance\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-supply fastener for any assembly requiring a 1\/4-28 UNF hex socket cap screw with a 1-3\/4 inch length under head per ASME\/ANSI B18.3.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a 3\/16-inch hex key or appropriate socket driver.
