Built to Grade 8 steel specifications, this fastener delivers the tensile strength required for heavy-duty bolted connections in industrial, commercial, and trade service environments. The 1-1\/4-7 UNC thread profile and 3-1\/2 inch length under head make it suited for thick-flange and structural-member assemblies. A zinc yellow dichromate finish provides corrosion resistance in demanding service conditions. Sold in a package quantity of 5, this fastener meets ASME B18.2.1 dimensional standards for consistent fit and function across standard hex tooling.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in applications requiring high-load fastening with fully threaded engagement, such as HVAC equipment mounting, mechanical equipment bases, structural steel connections, and heavy industrial assemblies. The UNC thread form is standard across the inch-measurement fastener market, making this screw compatible with a wide range of tapped holes and nuts in general trade and mechanical service work. Licensed tradespeople across HVAC, plumbing, and mechanical contracting regularly specify Grade 8 hex head fasteners where vibration resistance and high clamp load are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile and proof load strength in demanding fastening applications\u003c\/li\u003e\n  \u003cli\u003eFully threaded body along the 3-1\/2 inch length under head for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003e1-1\/4-7 UNC thread standard ensures compatibility with standard inch-series tapped holes and hex nuts\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish provides corrosion resistance in industrial and outdoor service environments\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standards for consistent fit with standard hex tooling\u003c\/li\u003e\n  \u003cli\u003eSold in a package of 5 units with a minimum order quantity of 1 package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1-1\/4-7 UNC inch-series tapped holes, hex nuts, and washers in mechanical and structural fastening applications.
