This screw features a 1\/4-20 UNC thread size, a 1-1\/2 inch length under head, and a 3\/16 inch hex drive socket. Constructed from alloy steel with a zinc-plated finish, it delivers solid corrosion resistance and mechanical strength. The partially threaded shank allows for precise clamping force and is suited to applications where thread engagement at depth is required. Licensed tradespeople and assemblers working in mechanical, HVAC, plumbing, and electrical panel assembly applications commonly specify this fastener type.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is appropriate for use in light industrial, commercial, and residential mechanical assemblies where a socket-drive fastener is preferred over hex head styles. The hex socket drive allows use in recessed or tight-clearance locations where a standard wrench cannot seat. Zinc plating provides a baseline level of corrosion protection suitable for indoor and sheltered environments. This screw is sold individually per package, with a minimum order quantity of 100 units, making it practical for bulk service inventory or job-site restocking.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC thread size for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e1-1\/2 inch length under head with partial threading for controlled clamping\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch hex socket drive for use with standard Allen or hex keys\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for high tensile strength\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish per ASTM B695 for corrosion resistance in indoor environments\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 100 units for job-site or service-stock use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-20 UNC hex socket cap screw for use in any application requiring a partially threaded alloy steel socket cap fastener with a 1-1\/2 inch length under head and zinc-plated finish.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 3\/16 inch hex key or Allen wrench; use of an appropriately sized and calibrated torque wrench is recommended to avoid stripping the socket or over-stressing the threaded joint. Confirm that the mating tapped hole is clean, properly formed to 1\/4-20 UNC standards, and free of debris before driving the screw. Always de-energize and lock out any equipment before replacing or tightening fasteners on powered assemblies. Follow applicable mechanical and structural codes for the specific installation environment.\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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-1\/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\/16 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: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASTM B695\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100 units\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 837157PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691062329650,"sku":"837157PR","price":2972.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e546eb415c0d9f6dfd1614c5f310a66f.jpg?v=1788279899","url":"https:\/\/voomisupply.com\/products\/value-collection-837157pr-hex-socket-cap-screw-1-4-20-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
