Manufactured from Grade 8 steel and finished with a zinc yellow dichromate coating, this fastener delivers superior tensile strength and corrosion resistance compared to lower-grade alternatives. The 3\/8-24 UNF thread pattern provides fine-thread engagement suited for applications requiring precise clamping force and vibration resistance. With a 1-1\/4-inch length under head and full threading along the shank, it is well suited for through-bolting or deep-thread applications in metal assemblies. Tradespeople and mechanical technicians working on equipment, brackets, or structural assemblies will find this screw meets demanding load requirements.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in industrial, mechanical, and trade applications where Grade 8 strength is specified. The fine UNF thread makes it a common choice for automotive, HVAC equipment frames, electrical enclosures, and general mechanical assemblies where vibration or dynamic loading is a concern. The zinc yellow dichromate finish adds a layer of corrosion protection suitable for indoor and light-duty outdoor environments. Sold individually with a minimum order quantity of 25 pieces, this fastener fits standard hex drive tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction provides high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish offers corrosion resistance and visual identification of high-strength grade\u003c\/li\u003e\n  \u003cli\u003e3\/8-24 UNF fine thread for secure engagement and vibration resistance\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank maximizes thread engagement length\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 and SAE J429 standards for dimensional and mechanical conformance\u003c\/li\u003e\n  \u003cli\u003eStandard hex head accepts common wrenches and sockets for fast installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNF inch-series hex head cap screw compatible with any 3\/8-24 tapped hole or nut conforming to ASME B18.2.1 and SAE J429 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or tradesperson using a calibrated torque wrench sized for 3\/8-inch hex fasteners.
