It features a 1\/4-20 UNC thread with a 2-1\/2-inch length under the head and is partially threaded, allowing for controlled clamping force without thread engagement through the full grip length. The 3\/16-inch hex drive socket accepts a standard Allen or hex key. Manufactured from 4037 alloy steel with a yellow cadmium-plated finish, the fastener offers corrosion resistance and meets ASME B18.3 dimensional standards. It is installed by machinists, maintenance technicians, and assemblers across industrial, aerospace, and general mechanical environments.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for applications requiring a recessed-drive, high-strength fastener in tight spaces where a wrench or external hex is impractical. The partial threading makes it appropriate for through-hole assemblies where the unthreaded shank carries shear loads. The yellow cadmium coating adds mild corrosion protection and provides visual identification for specification compliance. Typical use cases include machine frames, fixtures, tooling plates, and general industrial equipment requiring a repeatable, torque-controlled joint.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC thread size for wide compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e2-1\/2 inches length under head, partially threaded for shear-load applications\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch hex socket drive for access in confined spaces\u003c\/li\u003e\n  \u003cli\u003e4037 alloy steel construction for high tensile strength\u003c\/li\u003e\n  \u003cli\u003eYellow cadmium-plated finish for corrosion resistance and spec identification\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.3 dimensional standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-specification fastener for any assembly calling out a 1\/4-20 UNC hex socket cap screw per ASME B18.3 with a 2-1\/2-inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 3\/16-inch hex key or Allen driver; use a calibrated torque wrench when a torque specification is called out in the assembly drawing. Cadmium-plated fasteners should be handled with appropriate personal protective equipment, as cadmium is a regulated substance under occupational safety guidelines. Ensure the mating tapped hole is clean and free of debris before installation. Do not mix thread classes or substitute a different drive size, as this can damage the socket recess.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 4037\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Yellow Cadmium-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME B18.3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.37 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MS16997-68\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722966827314,"sku":"MS16997-68","price":179.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/05fe21a50f54bdb4b0e304e281d4664c.jpg?v=1788598598","url":"https:\/\/voomisupply.com\/products\/value-collection-ms16997-68-hex-socket-cap-screw-1-4-20","provider":"Voomi Supply","version":"1.0","type":"link"}
