It features a 5-40 UNC thread size with a 1-1\/2 inch length under head and is partially threaded along its shank. The drive type is hex, accepting a 3\/32 inch hex key. Constructed from alloy steel with a black oxide finish coating, this screw delivers corrosion resistance and a clean finished appearance. It conforms to ASME\/ANSI B18.3 and ASTM A574 standards, making it suitable for precision mechanical and industrial assembly work.\u003c\/p\u003e\n\u003cp\u003eThis fastener is commonly used in machinery, tooling fixtures, electronic enclosures, and light fabrication assemblies where a flush or low-profile cap head and internal hex drive are required. The 5-40 UNC thread is a fine-pitch unified coarse thread standard frequently found in small-bore precision components. Installation is performed by machinists, maintenance technicians, and assembly professionals using a standard 3\/32 inch hex key or T-handle driver.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5-40 UNC thread size with 1-1\/2 inch length under head\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank for precise clamping and load distribution\u003c\/li\u003e\n  \u003cli\u003e3\/32 inch hex drive for use with standard hex keys or drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish coating provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-stock fastener for any application specifying a 5-40 UNC hex socket cap screw conforming to ASME\/ANSI B18.3 and ASTM A574.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists or mechanical assembly technicians using a 3\/32 inch hex key or driver.
