Manufactured from alloy steel with a black oxide finish, this fastener measures 1 inch in length under the head and is fully threaded with a UNF thread form. The low-profile button head provides a smooth, rounded bearing surface suited for applications where standard hex cap screw heads would protrude excessively. Drive engagement is achieved with a 7\/32-inch hex socket. This screw is installed by machinists, millwrights, and general tradespeople working on equipment assembly, tooling, and mechanical maintenance tasks.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for use in light to medium-duty clamping and fastening applications where a flush or low-profile head profile is required. The alloy steel construction and black oxide finish provide moderate corrosion resistance in indoor and sheltered environments. The 3\/8-24 UNF thread designation makes it appropriate for fine-thread applications where precise clamping force control and vibration resistance are priorities. Packaged in quantities of 50 per order, this screw is commonly used in production runs, maintenance stocking, and shop inventory replenishment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-24 UNF fully threaded, right-hand thread with a 3A thread fit class for precise engagement\u003c\/li\u003e\n  \u003cli\u003eButton head profile with 7\/32-inch hex socket drive for low-clearance installations\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction with 36-43 HRC hardness range for reliable load-bearing performance\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduced light reflection\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI\/ASME B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n  \u003cli\u003eSold in a package of 50 pieces with a minimum order quantity of 1 package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNF button socket cap screw per ANSI\/ASME B18.3 and ASTM F835 for use in any application requiring a 3\/8-24 fine-thread alloy steel fastener with a low-profile button head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a calibrated 7\/32-inch hex key or socket driver. Ensure mating threads are clean and free of debris before installation. Verify thread engagement depth and torque requirements based on joint design specifications and applicable standards such as ASME guidelines.
