Sized at 6-32 UNC with a 3\/8-inch length under the head, this screw is fully threaded and accepts a 7\/64-inch hex drive. Manufactured from alloy steel with a black oxide finish, it meets ASME B18.3 and ASTM A574 standards, making it a reliable choice for mechanical assemblies, equipment enclosures, and maintenance work across industrial and trade settings. Licensed electricians, HVAC technicians, and millwrights commonly use socket cap screws like this when torque access is limited or a flush, clean fastener installation is needed.\u003c\/p\u003e\n\u003cp\u003eThis screw suits applications where a standard hex head would interfere with adjacent components or panels. It is well suited for use in electrical enclosures, control panels, HVAC equipment housings, pump assemblies, and general mechanical equipment. The 6-32 UNC thread is a fine-pitch, coarse-series unified inch thread commonly found in light-duty machine and equipment fastening. Fully threaded construction maximizes grip across the entire length under the head, which is especially useful in thin-material applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6-32 UNC fully threaded for consistent grip across the full 3\/8-inch shank length\u003c\/li\u003e\n  \u003cli\u003e7\/64-inch internal hex drive for use with standard hex keys or Allen drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical property requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light reflection in service environments\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.3 dimensional standards for socket cap screws\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 6-32 UNC socket cap screw per ASME B18.3, suitable for use in any application calling for a 6-32 UNC fully threaded hex socket cap screw with a 3\/8-inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall and remove using a 7\/64-inch hex key or T-handle driver. De-energize and lock out any electrical or mechanical equipment before accessing fastener locations inside panels or enclosures. Avoid overtightening in thin-gauge sheet metal or plastic-threaded bosses, as alloy steel fasteners can strip soft parent materials. Follow applicable NEC or equipment manufacturer torque guidelines when installing in electrical enclosures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 6-32 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3\/8 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: 7\/64 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 Coating\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME B18.3, ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: HOLO-KROME\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 72040\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51749875384626,"sku":"72040","price":5842.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/58de18327fe7af504e8fe6c31f57ee88.jpg?v=1788911544","url":"https:\/\/voomisupply.com\/products\/holo-krome-72040-hex-socket-cap-screw-6-32-unc-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
