It features a 1\/4-20 UNC thread size, a 3-3\/4 inch length under head, and a 3\/16 inch hex drive. The fastener is machined from alloy steel and finished with an Armor Coat coating for corrosion resistance. It is partially threaded, following the ASME B18.3 standard, making it well suited for applications requiring a bearing surface on the unthreaded shank. Trade professionals install these where high-strength, recessed-drive fasteners are required in tight clearance conditions.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in commercial and residential mechanical assemblies, equipment mounting, and structural fastening where a socket head cap screw profile is specified. The 1\/4-20 UNC thread is one of the most common unified coarse thread sizes found in HVAC equipment frames, pump housings, compressor mounts, and general mechanical enclosures. The Armor Coat finish adds durability in environments with moisture exposure or chemical contact. Sold individually with a minimum order quantity of 5 pieces per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e3-3\/4 inch length under head provides generous grip range for thick material stacks\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch hex drive size for use with standard Allen or hex key sets\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank per ASME B18.3 for precise clamping and shank-bearing loads\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction delivers high tensile and shear strength\u003c\/li\u003e\n  \u003cli\u003eArmor Coat finish for corrosion and wear resistance in harsh service environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME B18.3 hex socket cap screw for use in any application requiring a 1\/4-20 UNC partially threaded fastener with a 3\/16 inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a 3\/16 inch hex key or Allen driver; use a torque-limiting driver where specified by the equipment manufacturer.
