Threaded 1\/4-28 UNF and measuring 1 inch in length under the head, this screw is fully threaded along its entire shank. The 3\/16-inch hex socket drive accepts a standard Allen wrench or hex key. Manufactured from alloy steel with a black oxide finish, it meets ASME B18.3 and ASTM A574 standards. It is commonly installed by millwrights, maintenance technicians, and mechanical contractors working on precision assemblies where flush or countersunk fastening is required.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in tight clearance areas where a conventional hex head fastener cannot be driven. The fine UNF thread pitch provides strong clamping force and resistance to loosening under vibration, making it a practical choice for equipment panels, machine guards, brackets, and similar mechanical assemblies in both industrial and light commercial settings. Minimum order quantity is 100 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-28 UNF fine thread for high clamping force and vibration resistance\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank along the entire 1-inch length under head\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch hex socket drive for Allen wrench or hex key 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 reduces light reflection\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.3 dimensional standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-28 UNF hex socket cap screw per ASME B18.3, compatible with any tapped hole or threaded insert sized to 1\/4-28 UNF specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a 3\/16-inch hex key or Allen wrench; do not use an undersized key as it may strip the socket.
