It features a 3\/16-inch hex drive and a 1-1\/2-inch length under head with partial threading. Constructed from 18-8 stainless steel, this fastener offers solid corrosion resistance and is suited for environments where mild chemical exposure or moisture is a factor. Machinists, maintenance technicians, and mechanical contractors install this type of fastener when a recessed-drive, low-profile cap screw is required in tight assemblies.\u003c\/p\u003e\n\u003cp\u003eThis screw is commonly used in light-duty to medium-duty mechanical assemblies found in HVAC equipment, pump housings, electrical enclosures, and general industrial machinery. The 1\/4-20 UNC thread form is one of the most widely used unified coarse thread sizes in North American trade work, making this screw a standard fit across many fastener applications. It is sold individually but carries a minimum order quantity of 100 pieces per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC thread size for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e1-1\/2-inch length under head provides adequate grip for medium-depth assemblies\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch hex socket drive accepts standard hex keys and Allen-drive bits\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank allows precise clamping without full thread engagement through the fastened material\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction resists corrosion in wet or chemically exposed environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-20 UNC hex socket cap screw suitable for any tapped hole or threaded insert conforming to the UNC 1\/4-20 thread standard in mechanical, HVAC, or industrial assembly applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a 3\/16-inch hex key or Allen-drive bit; avoid over-torquing stainless steel fasteners, as galling can permanently seize the thread engagement.
