Sized at 1\/4-20 UNC thread by 1-3\/4 inches overall length and fully threaded, this screw features an 82-degree flat head driven by a 5\/32-inch hex socket. The body is machined from alloy steel and finished in black oxide for moderate corrosion resistance and reduced light reflection. It meets ASME\/ANSI B18.3 and ASTM F835 fastener standards. Machinists, millwrights, and maintenance technicians commonly use this fastener where a protruding head would interfere with mating surfaces or moving parts.\u003c\/p\u003e\u003cp\u003eThis flat socket cap screw is suited for general industrial assembly, machine guarding, fixture building, and equipment maintenance in both shop and field environments. The 1\/4-20 UNC thread is one of the most widely used coarse-thread sizes in inch-standard mechanical assemblies, making this screw a common stock item across manufacturing, fabrication, and maintenance operations. The black oxide finish provides a clean appearance and light surface protection in dry or low-moisture environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e82-degree flat head seats flush in standard countersunk holes for a low-profile installation\u003c\/li\u003e\n\u003cli\u003e5\/32-inch hex socket drive for precise torque application with standard Allen keys or hex bit drivers\u003c\/li\u003e\n\u003cli\u003eFully threaded along the 1-3\/4-inch overall length for maximum thread engagement in thinner materials\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction provides higher tensile strength than standard steel fasteners\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish reduces glare and offers light surface corrosion resistance in dry service conditions\u003c\/li\u003e\n\u003cli\u003eConforms to ASME\/ANSI B18.3 and ASTM F835 dimensional and mechanical standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1\/4-20 UNC tapped holes or clearance-drilled and countersunk assemblies using the inch system of measurement.

Ensure the mating countersink is machined to an 82-degree included angle for proper head seating. De-energize or lock out equipment before fastener installation or removal per applicable OSHA lockout\/tagout procedures. Do not over-torque alloy steel screws in soft or tapped aluminum substrates without referencing the assembly torque specification.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003c\/strong\u003e: 1-3\/4 inches (overall)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: 82-degree Flat\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 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\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM F835\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: -36817-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690570416434,"sku":"-36817-1","price":21.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/95d82fbdc3e2b8ea9de45265e44718f6.jpg?v=1788271883","url":"https:\/\/voomisupply.com\/products\/value-collection-36817-1-flat-socket-cap-screw-1-4-20","provider":"Voomi Supply","version":"1.0","type":"link"}
