It features an 82-degree flat head with a 5\/16-inch hex socket drive, allowing installation with a standard hex key. The 1\/2-13 UNC thread and 3-inch overall length make it suited for medium-to-heavy fastening tasks. Manufactured from alloy steel with a black oxide finish, it offers solid mechanical strength and moderate corrosion resistance. Partial threading allows the unthreaded shank to act as a shoulder in clearance holes. Machinists, millwrights, and maintenance technicians are the primary installers of this fastener.\u003c\/p\u003e\u003cp\u003eThis screw is commonly used in machinery frames, fixtures, tooling plates, and structural fabrication where a flush or recountersunk head profile is required. The UNC thread standard makes it compatible with standard inch-series tapped holes. Applications span general industrial maintenance, OEM machine assembly, and fabrication shops. The black oxide finish is suited for indoor or low-moisture environments where a dark, low-reflectance appearance is also desired.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e82-degree flat head profile seats flush in standard countersunk holes\u003c\/li\u003e\n\u003cli\u003e5\/16-inch hex socket drive for torque application with a hex key or hex bit driver\u003c\/li\u003e\n\u003cli\u003e1\/2-13 UNC thread for compatibility with standard inch-series tapped holes\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank functions as a shoulder in clearance-fit assemblies\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction provides high tensile and shear strength\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish reduces surface reflectance and offers light corrosion resistance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard inch-series flat socket cap screw for use in any application requiring a 1\/2-13 UNC tapped hole and a countersunk head seating at 82 degrees per ASME\/ANSI B18.3 and ASTM F835 standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 5\/16-inch hex key or hex bit driver. The mating hole must be countersunk to 82 degrees to achieve proper head seating. Confirm the tapped hole meets 1\/2-13 UNC specifications before installation.
