It features a 1-3\/8-6 UNC thread size with a 5-inch length under the head and is driven by a 1-inch hex (Allen) key. Constructed from alloy steel with a black oxide finish, this fastener meets ASME\/ANSI B18.3 and ASTM A574 standards, making it suitable for demanding load-bearing assemblies. The partial threading configuration allows for precise clamping force in bolted joints.\u003c\/p\u003e\u003cp\u003eThis screw is used in heavy industrial equipment, machinery frames, structural fixtures, and fabrication projects where high tensile strength and a low-profile socket drive are required. The coarse 6 TPI UNC thread is well-suited for use in steel and iron components where rapid assembly and resistance to cross-threading are priorities. Maintenance technicians, millwrights, and fabricators commonly install this fastener in manufacturing and facility maintenance environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-3\/8-6 UNC coarse thread for use in steel and iron assemblies\u003c\/li\u003e\n\u003cli\u003e5-inch length under head provides adequate grip in thick material stacks\u003c\/li\u003e\n\u003cli\u003e1-inch hex drive socket for high-torque installation with standard Allen tooling\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 for high tensile strength requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light glare\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank allows precise clamping and shear load distribution\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard-fitment socket cap screw conforming to ASME\/ANSI B18.3 and ASTM A574 specifications, suitable for any application requiring a 1-3\/8-6 UNC hex socket cap screw.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by millwrights, maintenance mechanics, or fabricators using a 1-inch hex key or socket drive. Always de-energize and lock out equipment before replacing or tightening fasteners in machinery. Verify hole thread condition and apply appropriate thread lubricant or anti-seize compound as required by the application.
