Manufactured from alloy steel with a black oxide finish, this fastener meets ANSI\/ASME B18.3 and ASTM F835 standards. The screw measures 1-3\/4 inches under the head with a 5\/32 hex drive and a 3A thread fit class, making it appropriate for precision mechanical assemblies. Hardness is rated at 36-43 HRC. This package contains 25 pieces, suitable for job-site use or shop inventory.\u003c\/p\u003e\n\u003cp\u003eButton socket cap screws of this specification are commonly used in machinery, fixtures, enclosures, and fabricated assemblies where a low, rounded head profile reduces snagging and improves clearance. The black oxide coating provides mild corrosion resistance and reduces light reflection, which is beneficial in tool and die, automation, and general industrial settings. Licensed tradespeople including millwrights, mechanical contractors, and maintenance technicians typically install this type of fastener.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLow-profile button head with 5\/32 hex socket drive for torque application in tight spaces\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction rated at 36-43 HRC hardness for strength under load\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for mild corrosion resistance and reduced surface reflectivity\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shaft with right-hand UNC thread in 3A fit class for consistent engagement\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI\/ASME B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n  \u003cli\u003eSold in a 25-piece package with a minimum order quantity of 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC 1\/4-20 button socket cap screw suitable for use in any application requiring an ANSI\/ASME B18.3-compliant low-profile hex socket fastener in alloy steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a 5\/32 hex key or socket driver; ensure the mating thread is clean and free of debris before driving. De-energize or lock out any machinery before fastener installation or replacement in accordance with applicable OSHA lockout\/tagout procedures. Do not substitute a standard hex key for an impact driver on alloy socket screws, as this can damage the drive recess. Verify torque requirements based on the assembly specification for the parent application.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Fit Class\u003c\/strong\u003e: 3A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Button\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.1320 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: 5\/32\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\u003eHardness\u003c\/strong\u003e: 36-43 HRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ANSI\/ASME B18.3, ASTM F835\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 25 pieces\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: -40878-5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701603139890,"sku":"-40878-5","price":27.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/07585fa0bb03ce922f55426a844157f3.jpg?v=1788402300","url":"https:\/\/voomisupply.com\/products\/value-collection-40878-5-button-socket-cap-screw-25-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
