The screw features a 3\/16-inch hex drive socket and a 3\/4-inch length under head with full threading along the entire shank. Constructed from alloy steel and finished with a black oxide coating, it provides solid mechanical strength with moderate corrosion resistance in dry or lightly oiled environments. This fastener meets ASME\/ANSI B18.3 and ASTM A574 standards, making it appropriate for applications where dimensional and tensile consistency are required. Machinists, millwrights, and maintenance technicians commonly use this screw type in equipment panels, fixtures, and machine assemblies.\u003c\/p\u003e\n\u003cp\u003eThis hex socket cap screw is suited for general industrial and mechanical assembly tasks where a flush or recessed fastener head profile is needed. The 1\/4-20 UNC thread form is one of the most common unified coarse thread standards, compatible with a wide range of tapped holes, threaded inserts, and standard nuts across manufacturing, HVAC equipment assembly, and general maintenance work. The black oxide finish reduces surface reflectivity and provides light surface protection.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC fully threaded shank for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch length under head suits medium-depth fastening applications\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch hex socket drive for use with standard Allen or hex key tools\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 tensile requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating provides light corrosion resistance and low reflectivity\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any application requiring a 1\/4-20 UNC socket head cap screw with a 3\/4-inch grip length, including equipment enclosures, mechanical fixtures, and machine component assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 3\/16-inch hex key or Allen driver. Ensure the receiving hole is properly tapped to 1\/4-20 UNC before driving the fastener. Do not overtighten, as alloy steel cap screws in softer base materials can strip threads. Clean and inspect the threaded hole for debris before installation.\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: 0.75 inches\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\u003eThreading\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 33602\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689045754162,"sku":"33602","price":15.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/67184dab65c9e95674542fd1370dfd60.jpg?v=1788254200","url":"https:\/\/voomisupply.com\/products\/value-collection-33602-hex-socket-cap-screw-1-4-20-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
