It features a 1\/4-28 UNF thread size with a 3\/4 inch length under the head and is fully threaded from end to head. The 3\/16 inch hex drive accepts a standard Allen key or hex bit. Constructed from alloy steel with a black oxide finish, this screw offers solid tensile strength and moderate corrosion resistance in protected or lightly oiled environments. It meets ASME\/ANSI B18.3 and ASTM A574 fastener standards.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for general industrial, mechanical, and maintenance applications where a compact, low-profile socket head fastener is required. The fine 1\/4-28 UNF thread provides better thread engagement and vibration resistance compared to coarse-thread equivalents, making it a common choice in precision assemblies, machine frames, and equipment enclosures. Installation is straightforward using a 3\/16 inch hex key or hex bit driver. This item is sold individually but carries a minimum order quantity of 50 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-28 UNF fine thread for strong thread engagement and vibration resistance\u003c\/li\u003e\n  \u003cli\u003eFully threaded along the entire 3\/4 inch length under head\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch hex drive compatible with standard Allen keys and hex bit drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides a low-reflectance surface and mild corrosion protection in oiled or indoor environments\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 socket cap screw dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 hex socket cap screw suitable for use in any application requiring a 1\/4-28 UNF fully threaded socket head fastener with a 3\/16 inch drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall and remove using a 3\/16 inch hex key or hex bit; do not substitute an undersized or worn driver, as this can round the socket. Ensure the mating tapped hole is clean, free of debris, and correctly sized for 1\/4-28 UNF thread before installation. Apply a thread lubricant or anti-seize compound where required by the application to prevent galling on alloy steel fasteners.
