Sized at 5-40 UNC with a 2-inch length under head, this screw accepts a 3\/32-inch hex drive and features partial threading along the shank. Constructed from alloy steel with a black oxide finish coating, it meets ASME\/ANSI B18.3 and ASTM A574 standards, making it suitable for demanding mechanical and industrial assemblies where dimensional consistency and material strength are required.\u003c\/p\u003e\u003cp\u003eThis socket cap screw is used in light mechanical assemblies, precision instrumentation, electronics enclosures, and machine component fastening where a low-profile, high-torque drive is needed. The 5-40 UNC thread size fits fine-pitch tapped holes common in small-scale industrial and OEM applications. The partial threading allows the unthreaded shank to act as a shoulder in clearance-fit bores, providing controlled clamping and alignment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5-40 UNC thread size for fine-pitch tapped hole applications\u003c\/li\u003e\n\u003cli\u003e2-inch length under head with partial threading for shoulder-style clamping\u003c\/li\u003e\n\u003cli\u003e3\/32-inch hex socket drive for precise torque application in tight spaces\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n\u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 5-40 UNC hex socket cap screw for use in tapped holes conforming to ASME\/ANSI B18.3 specifications in light mechanical, instrumentation, and OEM assembly applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by machinists, maintenance technicians, or assembly personnel using a 3\/32-inch hex key or Allen driver. Ensure the receiving tapped hole is clean and free of debris before driving the screw. Do not overtighten, as the 5-40 thread size has a limited torque threshold. Follow applicable ASME or OEM torque guidelines for the specific assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5-40 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2 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\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially 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\/ANSI B18.3, ASTM A574\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 581179PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720488190258,"sku":"581179PR","price":1295.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/567d93bda4b9c5dd60f36f84e5190e36.jpg?v=1788564872","url":"https:\/\/voomisupply.com\/products\/value-collection-581179pr-hex-socket-cap-screw-5-40-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
