Manufactured from alloy steel with a black oxide coating, this screw delivers solid mechanical strength and moderate corrosion resistance in a compact 3-48 x 3\/8-inch form factor. The 1\/16-inch hex socket drive accepts a standard hex key or Allen wrench. Hardness is rated at 36 to 43 HRC, consistent with ASTM F835 requirements. This screw is fully threaded and conforms to ANSI\/ASME B18.3 dimensional standards. It is suited for machine assembly, tooling, and equipment panels where flush or near-flush head clearance is needed.\u003c\/p\u003e\u003cp\u003eThis button socket cap screw is used in light to medium-duty mechanical assemblies across manufacturing, industrial maintenance, and equipment fabrication applications. The 3-48 thread size targets small-diameter fastening tasks common in instrument panels, electronics enclosures, and precision machine components. The black oxide finish blends visually with dark anodized or painted surfaces and provides light oil retention for mild corrosion protection. Licensed trades and MRO technicians working with compact hardware will find this size appropriate for close-tolerance assemblies where a standard pan or hex head would interfere with adjacent components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eButton head profile provides low-profile seating and a smooth, rounded top surface\u003c\/li\u003e\n\u003cli\u003e1\/16-inch hex socket drive compatible with standard Allen keys and hex bit drivers\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction with 36 to 43 HRC hardness per ASTM F835\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating offers mild corrosion resistance and reduced light reflection\u003c\/li\u003e\n\u003cli\u003eFully threaded shank along the 3\/8-inch length under head\u003c\/li\u003e\n\u003cli\u003eUNC thread standard with Class 3A fit for consistent dimensional tolerance\u003c\/li\u003e\n\u003cli\u003eMeets ANSI\/ASME B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 3-48 UNC button socket cap screw per ANSI\/ASME B18.3, compatible with any tapped hole or threaded insert machined to 3-48 UNC Class 3B specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall using a 1\/16-inch hex key or hex socket bit driver; do not substitute a mismatched driver size, as this risks stripping the socket. Ensure the mating tapped hole is clean and free of debris before driving the screw. Do not exceed the torque capacity appropriate for a 3-48 alloy steel fastener in the mating material, and avoid overtightening in soft base materials such as aluminum or plastic. Follow applicable mechanical assembly standards for the application.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3-48\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: 3\/8 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: 0.0520 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: 1\/16 inches\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\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\u003eWeight\u003c\/strong\u003e: 0.01 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: 201015PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722749215026,"sku":"201015PR","price":4376.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cbe0634df60d89b403a8fe95897cacd.jpg?v=1788595323","url":"https:\/\/voomisupply.com\/products\/value-collection-201015pr-button-socket-cap-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
