Manufactured from Grade 8 steel with a zinc yellow dichromate finish, this fastener delivers strong clamping force and corrosion resistance in demanding environments. The 1\/4-20 UNC thread pattern and 1\/2-inch length under head make it a common choice for general assembly, equipment mounting, and structural connections where a high-tensile fastener is required. Meets ASME B18.2.1 dimensional standards. Sold in a pack of 50.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for residential and commercial mechanical installations, general fabrication, and trade service applications requiring a reliable high-strength inch-series fastener. The 1\/4-20 UNC thread is a widely used coarse-thread specification found across HVAC equipment, electrical enclosures, plumbing fixtures, pump housings, and general metalwork. Full threading along the shank provides maximum thread engagement in blind holes and thin material applications.\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 protection and visual identification\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank for maximum thread engagement in all material thicknesses\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC coarse thread — widely compatible across standard inch-series hardware\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 dimensional standard for hex head cap screws\u003c\/li\u003e\n  \u003cli\u003eSold in a 50-piece pack for job-site and service inventory use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 1\/4-20 UNC tapped holes and with matching 1\/4-20 hex nuts and washers.
