Threaded to the 4-40 UNC standard, this screw measures 1.25 inches in length under the head and accepts a 3\/32 inch hex drive. Manufactured from 18-8 stainless steel, it resists rust and oxidation in humid or wet environments. Its compact size and fine thread pitch make it well suited for instrument panels, electrical enclosures, and light mechanical assemblies. Installation requires a standard 3\/32 inch hex key or Allen driver.\u003c\/p\u003e\u003cp\u003eThis screw is used across a wide range of light-duty fastening applications in HVAC controls, electrical panels, plumbing fixtures, and mechanical equipment assemblies. The 4-40 UNC thread is a common choice for small component mounting where a secure, removable connection is needed. It is appropriate for both field service and shop assembly work where stainless steel is specified for corrosion performance or code compliance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-40 UNC thread for precise engagement in fine-thread tapped holes\u003c\/li\u003e\n\u003cli\u003e1.25 inch length under head for moderate material stack depth\u003c\/li\u003e\n\u003cli\u003e3\/32 inch hex socket drive for use with standard Allen keys\u003c\/li\u003e\n\u003cli\u003e18-8 stainless steel construction for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eSocket cap head style provides a low-profile, high-strength clamping surface\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or stock fastener for any application requiring a 4-40 UNC hex socket cap screw with a 1.25 inch length under head in 18-8 stainless steel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall using a 3\/32 inch hex key or Allen driver.
