This screw features a 5\/16-18 UNC thread size and measures 2.25 inches in length under the head. It is partially threaded, which provides a smooth shank section for shear load applications and precise joint clamping. Constructed from alloy steel with a zinc-plated finish, it offers solid corrosion resistance for general-purpose use in both indoor and light-duty outdoor environments. The 0.25-inch hex drive accepts a standard hex key or Allen wrench. This fastener meets ASME B18.8 and ASTM A574 standards.\u003c\/p\u003e\u003cp\u003eThis cap screw is suited for machinery assembly, equipment fabrication, tool fixtures, and maintenance applications across manufacturing, construction, and trade environments. The partially threaded shank makes it a practical choice when alignment and shear strength are priorities in the joint. It is commonly installed by mechanical technicians, millwrights, pipefitters, and general tradespeople working with threaded fastener assemblies in steel or ferrous components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/16-18 UNC thread size for broad tooling and hardware compatibility\u003c\/li\u003e\n\u003cli\u003e2.25-inch length under head with partial threading for shear load performance\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meeting ASTM A574 strength requirements\u003c\/li\u003e\n\u003cli\u003eZinc-plated finish provides corrosion resistance in general service environments\u003c\/li\u003e\n\u003cli\u003e0.25-inch hex drive compatible with standard hex keys and Allen wrenches\u003c\/li\u003e\n\u003cli\u003eMeets ASME B18.8 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 5\/16-18 UNC hex socket cap screw for use in any application requiring ASME B18.8 and ASTM A574 compliant fasteners in alloy steel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a calibrated torque wrench or hex key sized to 0.25 inches. Ensure mating threads are clean and free of debris before driving the fastener. Do not exceed the rated torque for the fastener grade, and avoid using impact tools that may overstress the alloy steel.
