Sized at 1\/2-13 UNC with a 4-inch length under the head, it accepts a 3\/8-inch hex drive for installation with an Allen wrench or hex bit. Constructed from alloy steel with a zinc-plated finish, this cap screw delivers solid mechanical strength along with basic corrosion resistance. It meets ASME B18.8 and ASTM A574 standards, making it appropriate for structural and mechanical applications where fastener integrity matters.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for general industrial, mechanical, and equipment assembly work where a socket head cap screw profile is required. Partial threading is typical in applications where the unthreaded shank must pass through a clearance hole before engaging a tapped bore, providing accurate alignment and load-bearing performance. Fabricators, millwrights, equipment technicians, and maintenance professionals commonly install this type of fastener in machinery frames, jigs, fixtures, and structural steel assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC thread size with partial threading for clearance-hole applications\u003c\/li\u003e\n  \u003cli\u003e4-inch length under head provides reach for thick material stacks\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch hex socket drive for Allen key or hex bit installation\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical property requirements\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides basic corrosion resistance in indoor and sheltered environments\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.8 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 fastener for any application calling for a 1\/2-13 UNC partially threaded hex socket cap screw with a 4-inch length under head, conforming to ASME B18.8 and ASTM A574 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a calibrated torque wrench with the correct 3\/8-inch hex bit to avoid rounding the socket drive.
