Constructed from 18-8 stainless steel, this fastener offers good corrosion resistance in wet or mildly corrosive environments. The fine 1\/4-28 UNF thread pitch provides strong clamping force and vibration resistance compared to coarse-thread equivalents. It is installed using a standard 3\/16-inch hex key or Allen-type driver. Technicians and tradespeople across HVAC, plumbing, electrical, and general mechanical assembly applications rely on socket cap screws like this one for close-tolerance fastening in confined spaces where a wrench cannot reach a bolt head.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for light to medium-duty fastening tasks in residential and commercial equipment assemblies, panel mounting, bracket attachment, and equipment access covers. The fine UNF thread makes it a common choice when vibration resistance or precise torque control is required. At 0.03 pounds per fastener, the R40694241 is well-suited for applications where weight is a consideration. It is typically used by HVAC technicians, pipefitters, electricians, and general maintenance trades in both field service and shop fabrication settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-28 UNF fine thread for vibration-resistant clamping in mechanical assemblies\u003c\/li\u003e\n  \u003cli\u003e2-inch length under head suits medium-depth through-bolt and tapped-hole applications\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch internal hex drive allows installation in tight clearance areas\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction provides corrosion resistance in wet or mildly corrosive environments\u003c\/li\u003e\n  \u003cli\u003eSocket cap head style allows flush or recessed installation where low-profile fastening is needed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-28 UNF hex socket cap screw suitable for any tapped or through-hole application requiring this thread size, drive type, and length under head in ferrous or non-ferrous assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a 3\/16-inch hex key or Allen driver; ensure the drive is fully seated before applying torque to avoid cam-out or drive damage. De-energize and lock out any equipment before replacing or tightening fasteners on electrical or mechanical assemblies. Verify thread engagement depth in tapped holes meets standard guidelines for the material being fastened. Do not over-torque stainless steel fasteners, as galling can occur — apply an appropriate anti-seize compound when fastening stainless into stainless threads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28 UNF\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 (Allen)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: R40694241\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714856354098,"sku":"R40694241","price":4798.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4eb688a9ab319201cf251fdad812687b.jpg?v=1788507059","url":"https:\/\/voomisupply.com\/products\/value-collection-r40694241-hex-socket-cap-screw-1-4-28","provider":"Voomi Supply","version":"1.0","type":"link"}
