Threaded 4-48 UNF fully along its 5\/8-inch length under head, this screw accepts a 3\/32-inch hex drive for installation with standard Allen keys or hex bit drivers. Manufactured from alloy steel and finished with a black oxide coating, it delivers solid mechanical performance with moderate corrosion resistance in controlled environments. This fastener meets ASME\/ANSI B18.3 and ASTM A574 standards, making it suitable for applications where dimensional and strength compliance is required by specification. Machinists, maintenance technicians, and precision assemblers are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for light mechanical assemblies, instrumentation, tooling fixtures, and precision equipment where fine-thread engagement is needed in tight spaces. The 4-48 UNF thread series is a fine-pitch designation commonly used in small assemblies that require increased thread engagement strength and reduced backlash compared to coarse-thread alternatives. The black oxide finish is appropriate for interior or dry-environment applications where mild surface protection is acceptable. These screws are sold in minimum order quantities of 100 pieces per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-48 UNF fine thread for high thread-engagement strength in small assemblies\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch length under head, fully threaded along entire shank\u003c\/li\u003e\n  \u003cli\u003e3\/32-inch hex socket drive for use with standard Allen keys or hex bit drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-dimension hex socket cap screw per ASME\/ANSI B18.3 for use in any application requiring a 4-48 UNF fully threaded socket head fastener with a 3\/32-inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a calibrated 3\/32-inch hex key or hex bit driver to avoid rounding the drive socket. Verify that the mating tapped hole conforms to 4-48 UNF thread form and depth before installation.
